JP7717154B2 - Tobacco sheet for non-combustion heating type flavor inhaler and manufacturing method thereof, non-combustion heating type flavor inhaler, and non-combustion heating type flavor inhaler system - Google Patents

Description

The present invention relates to a tobacco sheet for a non-combustion heating type flavor inhaler and a method for manufacturing the same, a non-combustion heating type flavor inhaler, and a non-combustion heating type flavor inhalation system.

In combustion-type flavor inhalers (cigarettes), flavor is obtained by burning a tobacco filler containing tobacco leaves or a tobacco sheet. Patent Document 1, for example, discloses a tobacco sheet for use in a combustion-type flavor inhaler. As an alternative to combustion-type flavor inhalers, non-combustion-heating flavor inhalers have been proposed, which obtain flavor by heating a flavor source such as a tobacco sheet instead of burning it. The heating temperature of non-combustion-heating flavor inhalers is lower than the combustion temperature of combustion-type flavor inhalers, for example, approximately 400°C or lower. Because the heating temperature of non-combustion-heating flavor inhalers is thus low, an aerosol-generating agent can be added to the flavor source in non-combustion-heating flavor inhalers to increase the amount of smoke. The aerosol-generating agent vaporizes upon heating, generating an aerosol. The aerosol is supplied to the user along with flavor components such as tobacco components, allowing the user to enjoy a sufficient amount of flavor.

A non-combustion heating type flavor inhaler may include, for example, a tobacco-containing segment filled with a tobacco sheet or the like, a cooling segment, and a filter segment. The axial length of the tobacco-containing segment in a non-combustion heating type flavor inhaler is typically shorter than the axial length of the tobacco-containing segment in a combustion type flavor inhaler due to its relationship to the heater. Therefore, in a non-combustion heating type flavor inhaler, a large amount of tobacco sheet is filled within the short tobacco-containing segment to ensure the amount of aerosol generated during heating. To fill a large amount of tobacco sheet within a short section, a non-combustion heating type flavor inhaler typically uses a tobacco sheet with low expansion bulk, i.e., a high density. Incidentally, expansion bulk is a value that indicates the volume when a predetermined mass of tobacco sheet shreds is compressed at a constant pressure for a certain period of time.

Special Publication No. 60-45914

However, the inventors have found that when considering the heating method, the heating capacity of the heater, and the generation of aerosol, using a tobacco sheet with low bulk (high density) increases the total heat capacity of the tobacco-containing segment, and therefore, depending on the heating method and heater capacity, the tobacco sheet filled in the tobacco-containing segment does not contribute sufficiently to aerosol generation. Reducing the total heat capacity of the tobacco-containing segment is one possible solution to this problem.

The inventors have considered (1) reducing the specific heat of the tobacco raw material contained in the tobacco sheet, and (2) using a tobacco sheet with high expansion volume (low density) in order to reduce the total heat capacity of the tobacco-containing segment. However, since it is difficult to reduce the specific heat of the tobacco raw material itself in (1), it was considered effective to reduce the total heat capacity of the tobacco-containing segment by (2). Therefore, it is desirable to develop a tobacco sheet with high expansion volume (low density) that is suitable for use in non-combustion heating flavor inhalers.

The present invention aims to provide a highly expandable tobacco sheet for a non-combustion heating type flavor inhaler, a non-combustion heating type flavor inhaler including the tobacco sheet, and a non-combustion heating type flavor inhalation system.

[Tobacco sheet for non-combustion heating type flavor inhaler]
The tobacco sheet for a non-combustion heating-type flavor inhaler (hereinafter also referred to as "tobacco sheet") according to this embodiment contains tobacco raw materials, and the cross section of the tobacco sheet in the thickness direction has a corrugated shape. Because the cross section of the tobacco sheet in the thickness direction is corrugated, it is bulky and has high expandability. Therefore, by using the tobacco sheet according to this embodiment, the total heat capacity of the tobacco-containing segment can be reduced, and the tobacco sheet filled in the tobacco-containing segment can be made to contribute sufficiently to aerosol generation. Furthermore, the tobacco sheet according to this embodiment preferably further contains an aerosol-generating agent and one or more molding agents, and by setting the blending ratios of these within a predetermined range, the expandability of the tobacco sheet can be further improved.

(Tobacco sheet shape)
The tobacco sheet according to this embodiment has a wave-shaped cross section in the thickness direction. That is, when the tobacco sheet according to this embodiment is cut in the thickness direction in one of the planar directions, the cross section has a wave-shaped shape. The one planar direction may be, for example, the longitudinal direction or the lateral direction of the tobacco sheet. Here, the "wave-shaped" is not particularly limited as long as it is a shape that undulates up and down, and the crests of the waves may be linear or curved. Furthermore, the waves may be regular or irregular.

An example of the cross-sectional shape in the thickness direction of a tobacco sheet according to this embodiment is shown in Figure 1. The tobacco sheet 1 shown in Figure 1 has waves 2 in the cross-section in the thickness direction. The width w1 of the waves 2 is not particularly limited, but is preferably within the range of 0.1 to 10.0 mm. The height w2 of the waves 2 is also not particularly limited, but is preferably within the range of 0.1 to 5.0 mm. The thickness w3 of the tobacco sheet 1 is preferably within the range of 100 to 1000 μm. As shown in Figure 1, the waves 2 may have a sawtooth shape 3. When the waves 2 have a sawtooth shape 3, the tips of the sawtooth shapes come into contact with each other in the tobacco sheet mixture, thereby forming more voids, and as a result, further improving the expansion capacity. The size in the planar direction of the tobacco sheet according to this embodiment is not particularly limited, but can be, for example, a length of 5.0 to 40.0 mm and a width of 0.5 to 2.0 mm.

(Tobacco raw materials)
The tobacco raw material contained in the tobacco sheet according to this embodiment is not particularly limited as long as it contains tobacco components, and examples thereof include tobacco powder and tobacco extract. Examples of tobacco powder include tobacco leaves, midribs, and stem residues. These may be used alone or in combination. These can be used as tobacco powder by cutting them to a predetermined size. From the perspective of further improving swelling, it is preferable that the size of the tobacco powder be such that the cumulative 90% particle diameter (D90) in the volume-based particle size distribution measured by dry laser diffraction is 200 μm or more. When the tobacco raw material is tobacco powder, the proportion of tobacco powder contained in 100% by mass of the tobacco sheet is preferably 45 to 95% by mass, more preferably 50 to 93% by mass, and even more preferably 60 to 85% by mass. Examples of tobacco extracts include tobacco extracts obtained by coarsely crushing tobacco leaves, mixing and stirring the crushed leaves with a solvent such as water to extract water-soluble components from the tobacco leaves, and then concentrating the resulting aqueous extract by drying under reduced pressure.

(Aerosol Generator)
From the viewpoint of increasing the amount of smoke produced when heated, the tobacco sheet according to this embodiment preferably further contains an aerosol-generating agent. Examples of aerosol-generating agents include glycerin, propylene glycol, and 1,3-butanediol. These may be used alone or in combination of two or more.

When an aerosol-generating agent is included in the tobacco sheet, the proportion of the aerosol-generating agent in 100% by mass of the tobacco sheet is preferably 4 to 50% by mass. A proportion of the aerosol-generating agent of 4% by mass or more allows sufficient aerosol to be generated when heated in terms of quantity. Furthermore, a proportion of the aerosol-generating agent of 50% by mass or less allows sufficient aerosol to be generated when heated in terms of heat capacity. The proportion of the aerosol-generating agent is more preferably 6 to 40% by mass, even more preferably 8 to 30% by mass, and particularly preferably 10 to 20% by mass.

(Molding agent)
From the viewpoint of maintaining the shape, the tobacco sheet according to this embodiment preferably further comprises a molding agent. In particular, from the viewpoint of being able to sufficiently balance the tobacco sheet's ability to retain the aerosol-generating agent and its ability to maintain the corrugated shape, the tobacco sheet according to this embodiment preferably further comprises a first molding agent and a second molding agent. Here, the first molding agent and the second molding agent may be of different types, or may be of the same type but different forms. Examples of the first molding agent include polysaccharides, proteins, synthetic polymers, etc. Examples of polysaccharides include cellulose derivatives and naturally occurring polysaccharides.

Examples of cellulose derivatives include cellulose ethers such as methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxymethylethyl cellulose, hydroxypropyl cellulose, hydroxypropylmethyl cellulose, benzyl cellulose, trityl cellulose, cyanoethyl cellulose, carboxymethyl cellulose, carboxyethyl cellulose, and aminoethyl cellulose; organic acid esters such as cellulose acetate, cellulose formate, cellulose propionate, cellulose butyrate, cellulose benzoate, cellulose phthalate, and tosyl cellulose; and inorganic acid esters such as cellulose nitrate, cellulose sulfate, cellulose phosphate, and cellulose xanthate.

Examples of naturally occurring polysaccharides include plant-derived polysaccharides such as guar gum, tara gum, locust bean gum, tamarind seed gum, pectin, gum arabic, tragacanth gum, karaya gum, ghatti gum, arabinogalactan, amaryllis seed gum, cassia gum, psyllium seed gum, and desert artemisia seed gum; algae-derived polysaccharides such as carrageenan, agar, alginic acid, propylene glycol alginate, furcellaran, and flavonoid extract; microbial polysaccharides such as xanthan gum, gellan gum, curdlan, pullulan, Agrobacterium succinoglycan, welan gum, macrophomopsis gum, and rhamsan gum; crustacean-derived polysaccharides such as chitin, chitosan, and glucosamine; and starches such as starch, sodium starch glycolate, pregelatinized starch, and dextrin.

Examples of proteins include grain proteins such as wheat gluten and rye gluten. Examples of synthetic polymers include polyphosphate, sodium polyacrylate, polyvinylpyrrolidone, etc. The second molding agent may be different from the first molding agent, but may be the same polysaccharides, proteins, synthetic polymers, etc. as the first molding agent.

When a tobacco sheet contains a first molding agent, the proportion of the first molding agent in 100% by mass of the tobacco sheet is preferably 0.1 to 15% by mass. Having a proportion of the first molding agent of 0.1% by mass or more makes it possible to easily mold the raw material mixture into a sheet. Furthermore, having a proportion of the first molding agent of 15% by mass or less allows for sufficient use of other raw materials to ensure the functionality required of the tobacco-containing segment of a non-combustion heating flavor inhaler. The proportion of the first molding agent is more preferably 0.1 to 12% by mass, even more preferably 0.1 to 10% by mass, and particularly preferably 0.1 to 7% by mass.

When a second molding agent is included in the tobacco sheet, the proportion of the second molding agent in 100% by mass of the tobacco sheet is preferably 0.1 to 15% by mass. Having a proportion of the second molding agent of 0.1% by mass or more makes it possible to easily mold the raw material mixture into a sheet. Furthermore, having a proportion of the second molding agent of 15% by mass or less allows for sufficient use of other raw materials to ensure the functionality required of the tobacco-containing segment of a non-combustion heating flavor inhaler. The proportion of the second molding agent is more preferably 0.1 to 12% by mass, even more preferably 0.1 to 10% by mass, and particularly preferably 0.1 to 7% by mass.

Furthermore, when the first and second molding agents are the same type of molding agent but in different forms, the first molding agent can be a powder and the second molding agent a solution or slurry, for example. For example, in the tobacco sheet manufacturing method described below, the molding agent can be directly mixed as a powder to serve as the first molding agent, and the molding agent can be dispersed or swollen in a solvent such as water and mixed as the second molding agent. This method also achieves the same effects as when two different types of molding agents are used.

(reinforcing agent)
The tobacco sheet according to this embodiment may further contain a reinforcing agent in order to further improve its physical properties. Examples of reinforcing agents include fibrous substances such as fibrous pulp and fibrous synthetic cellulose, and liquid substances with a surface coating function that form a film when dried, such as pectin suspensions. These may be used alone or in combination of two or more.

When a reinforcing agent is included in the tobacco sheet, the proportion of the reinforcing agent in 100% by mass of the tobacco sheet is preferably 4 to 40% by mass. Within this range, other ingredients can be used sufficiently to ensure the functionality required of the tobacco-containing segment of a non-combustion heating-type flavor inhaler. The proportion of the reinforcing agent is more preferably 4.5 to 35% by mass, and even more preferably 5 to 30% by mass.

(moisturizer)
From the viewpoint of maintaining quality, the tobacco sheet according to this embodiment may further contain a humectant. Examples of humectants include sugar alcohols such as sorbitol, erythritol, xylitol, maltitol, lactitol, mannitol, and reduced maltose syrup. These may be used alone or in combination of two or more.

When a tobacco sheet contains a humectant, the proportion of the humectant contained in 100% by mass of the tobacco sheet is preferably 1 to 15% by mass. Within this range, other ingredients can be used sufficiently to ensure the functionality required of the tobacco-containing segment of a non-combustion heating flavor inhaler. The proportion of the humectant is more preferably 2 to 12% by mass, and even more preferably 3 to 10% by mass.

(Other ingredients)
The tobacco sheet according to the present embodiment may contain, in addition to the tobacco raw material, the aerosol generating agent, the molding agent (first and second molding agents), the reinforcing agent, and the moisturizing agent, flavorings such as fragrances and taste enhancers, colorants, humectants, preservatives, diluents such as inorganic substances, and the like, as needed.

(bulkness)
The expansion capacity of the tobacco sheet according to this embodiment is preferably 190 cc/100 g or more. A expansion capacity of 190 cc/100 g or more allows the total heat capacity of the tobacco-containing segment of a non-combustion heating-type flavor inhaler to be sufficiently reduced, allowing the tobacco sheet filled in the tobacco-containing segment to contribute more to aerosol generation. The expansion capacity is more preferably 210 cc/100 g or more, and even more preferably 230 cc/100 g or more. The upper limit of the expansion capacity range is not particularly limited, but can be, for example, 800 cc/100 g or less. The expansion capacity is measured using a DD-60A (trade name, manufactured by Borgwald) measuring instrument after cutting the tobacco sheet into pieces of 0.8 mm x 20 mm and storing them in a conditioned room at 22°C and 60% humidity for 48 hours. The measurement is carried out by placing 15 g of shredded tobacco sheet in a cylindrical container with an inner diameter of 60 mm, and determining the volume when compressed under a load of 3 kg for 30 seconds.

[Tobacco sheet manufacturing method]
The tobacco sheet manufacturing method according to this embodiment can include, for example, the steps of preparing a mixture containing a tobacco raw material, an aerosol-generating agent, a first molding agent, and a second molding agent, rolling the mixture to form a rolled product, and pressing a rotary roll blade against the rolled product to cut it into strips and impart a corrugated shape to the rolled product. The process of imparting a corrugated shape is also called a rippling process. For example, the tobacco sheet according to this embodiment can be manufactured by the following method.

(1) A step of mixing water, tobacco raw material, an aerosol-generating agent, first and second molding agents, and a reinforcing agent to obtain a mixture.
(2) A step of rolling the mixture between a plurality of rolling rollers to obtain a rolled product.
(3) A process of pressing a rotary roll blade against the rolled product to cut it into strips and impart a corrugated shape to the rolled product.

When a sheet is cut into strips by a rotary roll blade, a resistance force is applied when the sheet is peeled off from the roll, imparting a wavy or sawtooth shape as shown in Figure 1. If the rolled product is not cut with a rotary roll blade, for example, the rolled product on the rolling roller can be peeled off with a doctor knife, which applies a resistance force when the sheet is peeled off from the roll, and similarly imparts a wavy or sawtooth shape. When producing tobacco sheets using the above method, the surfaces of the rolling rollers may be heated or cooled, and the rotation speed of the rolling rollers may be adjusted, depending on the purpose. Furthermore, by adjusting the spacing between the rolling rollers, a tobacco sheet of the desired basis weight can be obtained.

[Non-combustion heating type flavor inhaler]
The non-combustion heating type flavor inhaler according to this embodiment includes a tobacco-containing segment including the tobacco sheet according to this embodiment, etc. Because the non-combustion heating type flavor inhaler according to this embodiment includes a tobacco-containing segment filled with the highly expandable tobacco sheet according to this embodiment, the total heat capacity of the tobacco-containing segment can be sufficiently reduced, and the tobacco sheet filled in the tobacco-containing segment can contribute more to aerosol generation.

An example of a non-combustion heating type flavor inhaler according to this embodiment is shown in Figure 2. The non-combustion heating type flavor inhaler 4 shown in Figure 2 comprises a tobacco-containing segment 5 filled with a tobacco sheet or the like according to this embodiment, a cylindrical cooling segment 6 having perforations 11 on its circumference, a center hole segment 7, and a filter segment 8. The non-combustion heating type flavor inhaler according to this embodiment may also have other segments in addition to the tobacco-containing segment, cooling segment, center hole segment, and filter segment.

The axial length of the non-combustion heating type flavor inhaler according to this embodiment is not particularly limited, but is preferably 40 mm or more and 90 mm or less, more preferably 50 mm or more and 75 mm or less, and even more preferably 50 mm or more and 60 mm or less. The circumferential length of the non-combustion heating type flavor inhaler is preferably 16 mm or more and 25 mm or less, more preferably 20 mm or more and 24 mm or less, and even more preferably 21 mm or more and 23 mm or less. For example, the tobacco-containing segment may be 20 mm long, the cooling segment may be 20 mm long, the center hole segment may be 8 mm long, and the filter segment may be 7 mm long. The length of the filter segment may be selected within a range of 4 mm or more and 10 mm or less. The airflow resistance of the filter segment is selected to be 15 mm _H2O /seg or more and 60 mm _H2O /seg or less per segment. These individual segment lengths may be appropriately changed depending on manufacturing suitability, required quality, and the like. Furthermore, even if a center hole segment is not used and only a filter segment is disposed downstream of the cooling segment, it can still function as a non-combustion heating type flavor inhaler.

(Tobacco-containing segment)
The tobacco-containing segment 5 is formed by filling a tobacco sheet according to this embodiment into cigarette paper (hereinafter also referred to as a wrapper). The method for filling the tobacco sheet into the cigarette paper is not particularly limited, and for example, the tobacco sheet may be wrapped in the wrapper, or the tobacco sheet may be filled into a tubular wrapper. When the tobacco sheet has a longitudinal direction, such as a rectangular shape, the tobacco sheet may be filled so that the longitudinal direction is in an unspecified direction within the wrapper, or may be filled so that the tobacco sheet is aligned in the axial direction of the tobacco-containing segment 5 or perpendicular to the axial direction.

(Cooling segment)
2, the cooling segment 6 can be configured as a cylindrical member 10. The cylindrical member 10 may be, for example, a cardboard tube formed into a cylindrical shape.

The tubular member 10 and the mouthpiece lining paper 15 (described later) are provided with perforations 11 that penetrate both. The presence of the perforations 11 allows outside air to be introduced into the cooling segment 6 during inhalation. As a result, the vaporized aerosol components generated by heating the tobacco-containing segment 5 come into contact with the outside air, their temperature drops, and they liquefy, forming an aerosol. The diameter (distance across) of the perforations 11 is not particularly limited, but may be, for example, 0.5 mm or more and 1.5 mm or less. The number of perforations 11 is not particularly limited, and may be one, two, or more. For example, multiple perforations 11 may be provided around the circumference of the cooling segment 6.

The amount of outside air introduced through the perforations 11 is preferably 85% by volume or less, more preferably 80% by volume or less, of the total volume of gas inhaled by the user. By keeping the outside air volume ratio at 85% by volume or less, it is possible to sufficiently suppress the reduction in flavor due to dilution by outside air. This is also known as the ventilation ratio. From the perspective of cooling performance, the lower limit of the ventilation ratio range is preferably 55% by volume or more, more preferably 60% by volume or more.

The cooling segment may also be a segment comprising a wrinkled, pleated, gathered, or folded sheet of suitable construction material. The cross-sectional profile of such an element may exhibit randomly oriented channels. The cooling segment may also comprise a bundle of longitudinally extending tubes. Such a cooling segment may be formed, for example, by wrapping the pleated, gathered, or folded sheet material in a wrapping paper.

The axial length of the cooling segment can be, for example, 7 mm or more and 28 mm or less, for example, 18 mm. The cooling segment can also have a substantially circular axial cross-sectional shape, and its diameter can be, for example, 5 mm or more and 10 mm or less, for example, approximately 7 mm.

(Center hole segment)
The center hole segment is composed of a filling layer having one or more hollow portions and an inner plug wrapper (inner wrapping paper) covering the filling layer. For example, as shown in FIG. 2, the center hole segment 7 is composed of a second filling layer 12 having a hollow portion and a second inner plug wrapper 13 covering the second filling layer 12. The center hole segment 7 functions to increase the strength of the mouthpiece segment 9. The second filling layer 12 can be, for example, a rod with an inner diameter of 1.0 mm or more and 5.0 mm or less, which is densely packed with cellulose acetate fibers and hardened by adding a plasticizer containing triacetin in an amount of 6% by mass or more and 20% by mass or less relative to the mass of cellulose acetate. Because the second filling layer 12 has a high fiber packing density, during inhalation, air and aerosol flow only through the hollow portions, with almost no flow within the second filling layer 12. Because the second filling layer 12 inside the center hole segment 7 is a fiber-filled layer, the feel from the outside during use is less likely to cause discomfort to the user. It is also possible for the center hole segment 7 not to have the second inner plug wrapper 13 and for its shape to be maintained by thermoforming.

(filter segment)
The configuration of the filter segment 8 is not particularly limited, and may be composed of one or more packed layers. The packed layer may be wrapped with one or more sheets of wrapping paper. The airflow resistance per filter segment 8 can be appropriately changed depending on the amount and material of the filler filled in the filter segment 8. For example, when the filler is cellulose acetate fiber, the airflow resistance can be increased by increasing the amount of cellulose acetate fiber filled in the filter segment 8. When the filler is cellulose acetate fiber, the packing density of the cellulose acetate fiber can be 0.13 to 0.18 g/ ^cm3 . The airflow resistance is a value measured using an airflow resistance measuring device (product name: SODIMAX, manufactured by SODIM).

The circumferential length of the filter segment 8 is not particularly limited, but is preferably 16 to 25 mm, more preferably 20 to 24 mm, and even more preferably 21 to 23 mm. The axial length of the filter segment 8 can be selected from 4 to 10 mm, and is selected so that the airflow resistance is 15 to 60 mmH ₂ O/seg. The axial length of the filter segment 8 is preferably 5 to 9 mm, more preferably 6 to 8 mm. The cross-sectional shape of the filter segment 8 is not particularly limited, but may be, for example, circular, elliptical, polygonal, etc. In addition, a flavor-containing breakable capsule, flavor beads, or flavor may be directly added to the filter segment 8.

As shown in Figure 2, the center hole segment 7 and the filter segment 8 can be connected by an outer plug wrapper (outer wrapping paper) 14. The outer plug wrapper 14 can be, for example, a cylindrical piece of paper. The tobacco-containing segment 5, the cooling segment 6, and the connected center hole segment 7 and filter segment 8 can also be connected by a mouthpiece lining paper 15. These connections can be made, for example, by applying glue such as vinyl acetate glue to the inner surface of the mouthpiece lining paper 15, and then inserting and winding the three segments. Note that these segments may also be connected in multiple layers using multiple lining papers.

[Non-combustion heating type flavor inhalation system]
The non-combustion heating type flavor inhalation system according to this embodiment includes the non-combustion heating type flavor inhaler according to this embodiment and a heating device that heats the tobacco-containing segment of the non-combustion heating type flavor inhaler. The non-combustion heating type flavor inhalation system according to this embodiment may have other configurations in addition to the non-combustion heating type flavor inhaler according to this embodiment and the heating device.

An example of a non-combustion heating type flavor inhalation system according to this embodiment is shown in Figure 3. The non-combustion heating type flavor inhalation system shown in Figure 3 comprises a non-combustion heating type flavor inhaler 4 according to this embodiment and a heating device 16 that heats the tobacco-containing segment of the non-combustion heating type flavor inhaler 4 from the outside.

Figure 3(a) shows the state before the non-combustion heating type flavor inhaler 4 is inserted into the heating device 16, and Figure 3(b) shows the state after the non-combustion heating type flavor inhaler 4 is inserted into the heating device 16 and heated. The heating device 16 shown in Figure 3 comprises a body 17, a heater 18, a metal tube 19, a battery unit 20, and a control unit 21. The body 17 has a cylindrical recess 22, and the heater 18 and metal tube 19 are disposed on the inner side of the recess 22 at a position corresponding to the tobacco-containing segment of the non-combustion heating type flavor inhaler 4 inserted into the recess 22. The heater 18 may be an electrical resistance heater, and is heated by being supplied with power from the battery unit 20 in response to instructions from the temperature-controlling control unit 21. The heat generated by the heater 18 is transferred to the tobacco-containing segment of the non-combustion heating type flavor inhaler 4 via the metal tube 19, which has high thermal conductivity.

Figure 3(b) is a schematic illustration, and therefore shows a gap between the outer periphery of the non-combustion heating type flavor inhaler 4 and the inner periphery of the metal tube 19. However, in reality, for the purpose of efficient heat transfer, it is preferable that there be no gap between the outer periphery of the non-combustion heating type flavor inhaler 4 and the inner periphery of the metal tube 19. Note that although the heating device 16 heats the tobacco-containing segment of the non-combustion heating type flavor inhaler 4 from the outside, it may also heat from the inside.

The heating temperature of the heating device is not particularly limited, but is preferably 400°C or less, more preferably 150°C or more and 400°C or less, and even more preferably 200°C or more and 350°C or less. The heating temperature refers to the temperature of the heater of the heating device.

Furthermore, non-combustion heating type flavor inhalers are required to reduce the aroma taste inhibition (irritation) or unpleasant sensation. "Aroma taste inhibition" refers to the irritation to the oral cavity and throat during inhalation. Below, we will explain tobacco sheets for non-combustion heating type flavor inhalers that reduce aroma taste inhibition or unpleasant sensation.

[First Aspect]
In this embodiment, the tobacco sheet for a non-combustion heating-type flavor inhaler contains fructan. When the tobacco sheet is smoked, the fructan is thermally decomposed to generate a persistent sweet aroma. The generated persistent sweet aroma can suppress the unpleasant aroma and taste from the early to late stages of smoking.

The fructan may be, but is not limited to, an inulin-type fructan, a levan-type fructan, a branched fructan, a fructooligosaccharide, or a combination of two or more of these. Among these, inulin-type fructan is preferred from the perspective of cost reduction.

Without being bound by theory, it is presumed that when the fructan of this embodiment generates a sweet aroma through a caramelization reaction, it has the following characteristics.
Fructans are formed by the combination of multiple monosaccharides and have a molecular structure larger than that of monosaccharides and disaccharides. Therefore, when fructans undergo caramelization, they are decomposed into relatively small sugar molecules such as monosaccharides and disaccharides, and then these monosaccharides and disaccharides undergo caramelization to generate a sweet aroma, which is a multi-stage decomposition process. On the other hand, when monosaccharides and disaccharides undergo caramelization, these sugars undergo caramelization to directly generate a sweet aroma. Therefore, compared with monosaccharides and disaccharides, fructans undergo more decomposition processes, and are thought to be able to generate a sweet aroma at a slower rate and for a longer period of time. In this embodiment, due to the characteristics of the caramelization reaction of fructans, it is thought that the unpleasant aroma of smoking can be continuously suppressed from the early to late stages of smoking.

In some embodiments, the content of fructans relative to 100% by mass of the tobacco sheet is not particularly limited, but may be 0.1 to 5% by mass, 0.3 to 3.5% by mass, or 0.5 to 3% by mass. From the viewpoint of suppressing the perceived aroma and flavor inhibition and the sustainability of the suppression of the perceived aroma and flavor inhibition, a higher fructan content is preferable. On the other hand, if the fructan content is too high, the flavor may be reduced. Therefore, from the viewpoint of achieving both the suppression of the perceived aroma and flavor inhibition and the sustainability of the suppression, the fructan content is preferably 0.5 to 3% by mass.

In this embodiment, the tobacco raw material may further include tobacco leaves, cured tobacco leaves, processed tobacco leaves, tobacco filler, non-tobacco materials, or a combination of two or more of these.

<Tobacco leaves, cured tobacco leaves, and processed tobacco leaves>
"Tobacco leaf" is a general term for harvested tobacco leaves before undergoing the aging process described below. One form of aging includes curing. In contrast, aged tobacco leaves that have not yet been processed into various forms used in tobacco products (such as tobacco shreds, tobacco sheets, and tobacco granules, described below) are called "aged tobacco leaves." Furthermore, aged tobacco leaves that have been processed into various forms used in tobacco products are called "processed tobacco leaves."

Examples of the form of processed tobacco leaves used in tobacco products include "tobacco shreds," which are aged tobacco leaves shredded to a specified size. Other examples include "tobacco sheets," which are obtained by forming a composition containing aged tobacco leaves ground to a specified particle size (hereinafter also referred to as "tobacco powder") into a sheet shape, and "tobacco granules," which are obtained by forming the composition into a granular shape. The aforementioned "tobacco powder" is also a form of processed tobacco leaves.

Non-tobacco materials include plant roots (including bulbs, tuberous roots, bulbs, etc.), stems, tubers, bark (including stem bark, bark, etc.), leaves, flowers (including petals, pistils, stamens, etc.), seeds, or tree trunks and branches.

The method for producing a tobacco sheet containing fructan is not limited. In some embodiments of the present application, the tobacco sheet can be produced by preparing the tobacco sheet described above and supplying fructan from an external source. Specifically, it is preferable to supply fructan to the rolled product. The rolled product may be either before or after being given a corrugated shape.

[Second Aspect]
In this embodiment, the tobacco sheet for a non-combustion heating-type flavor inhaler contains a saturated fatty acid-based additive.
In this embodiment, the tobacco sheet may contain a material derived from an Orient species. In this case, the content of the material derived from an Orient species relative to the tobacco raw material is preferably 10% by mass or less. A content of the material derived from an Orient species within this range can provide a smoking taste with a reduced unpleasant feeling. From this perspective, the upper limit of the content is preferably 8% by mass or less, more preferably 5% by mass or less. The lower limit is preferably 0.1% by mass or more, more preferably 2% by mass or more, and even more preferably 3% by mass or more.

The saturated fatty acid additive is selected from the group consisting of saturated fatty acids with a molar mass of 200 to 350 g/mol, esters of such saturated fatty acids, and combinations thereof. The saturated fatty acids reduce the discomfort experienced when smoking. The saturated fatty acid esters are obtained from alcohol and saturated fatty acids with a molar mass of 200 to 350 g/mol, and therefore the molar mass of the esters varies depending on the molar mass of the alcohol. In one embodiment, the molar mass of the esters is 210 to 1300 g/mol. Esters of saturated fatty acids generally have a lower vapor pressure than fatty acids, and therefore the effect of reducing discomfort experienced when smoking is sustained throughout the entire smoking session. Hereinafter, the effect of reducing discomfort experienced when smoking will also be referred to simply as the discomfort reduction effect.

From the viewpoint of achieving the above-mentioned effect, the lower limit of the molar mass of the saturated fatty acid ester is preferably 240 g/mol or more, more preferably 270 g/mol or more. The upper limit is preferably 1140 g/mol or less, 1112 g/mol or less, 300 g/mol or less, or 290 g/mol or less.

The content of the saturated fatty acid additive is 0.01 to 3% by mass per total dry mass of the tobacco raw material (with the dry mass being 100% by mass). If the content is below the lower limit, the unpleasant sensation reduction effect will be insufficient, while if the content exceeds the upper limit, the unpleasant odor will increase. From this perspective, the lower limit of the content is preferably 1% by mass or more, and the upper limit is preferably 2% by mass or less. The dry mass is the mass excluding the medium described below, and is preferably the mass of the residue when the composition is dried at 100°C for 5 hours.

The number of carbon atoms in the saturated fatty acid and the fatty acid moiety in the ester is preferably 12 to 20, more preferably 15 to 19. When the number of carbon atoms is within this range, the effect of reducing discomfort becomes more pronounced.
The solubility of the saturated fatty acid in the saturated fatty acid-based additive in water is preferably 0.15 mg/g or less, more preferably 0.12 mg/g or less. The lower limit is not limited and may be 0 mg/g, but is preferably 0.05 mg/g or more.

Preferred examples of the saturated fatty acid include octanoic acid, decanoic acid, myristic acid, palmitic acid, stearic acid, and nonadecanoic acid. Among these, palmitic acid, stearic acid, and nonadecanoic acid are preferred from the standpoints of availability and the ability to reduce discomfort. The saturated fatty acid may be a mixture, but is preferably a single component rather than a mixture. In this embodiment, a single component (single compound) includes a pure compound or a compound containing unavoidable impurities. Therefore, in one embodiment, the saturated fatty acid consists solely of palmitic acid. When the saturated fatty acid is a single component, the dispersibility of the saturated fatty acid in the molded product, such as a sheet, is improved when the tobacco composition of the present invention is molded into the molded product.

Preferred examples of the esters of saturated fatty acids (hereinafter simply referred to as "esters") include alkyl esters and sugar esters of the saturated fatty acids. The alkyl moiety is preferably derived from a linear, branched, or cyclic alkyl group having 1 to 10 carbon atoms, such as a methyl group. The sugar moiety is preferably derived from a disaccharide such as sucrose. Preferred examples of the esters include sucrose palmitate and methyl palmitate. The saturated fatty acid moiety in the ester is preferably derived from a single saturated fatty acid for the reasons described above. The alcohol moiety in the ester does not need to be a single alcohol moiety, but is preferably a single alcohol moiety for the reasons described above. The ester also functions as an emulsifier.

In one aspect, the saturated fatty acid-based additive contains the saturated fatty acid and the ester. In this case, there is an advantage that the discomfort-reducing effect can be maintained for a longer period of time. In addition, the type of saturated fatty acid-based additive can be appropriately selected depending on the tobacco raw material used, etc. Therefore, this aspect also has the advantage of being versatile.

It is preferable that some or all of the saturated fatty acid additive is powder. If the saturated fatty acid additive is powder, the dispersibility of the saturated fatty acid additive in the molded product, such as a sheet, is improved when the additive is molded as described below. There are no restrictions on the size, but for example, the D50 is preferably 30 to 120 μm, and more preferably 50 to 100 μm. Furthermore, from the perspective of dispersibility, it is preferable that the saturated fatty acid additive has a higher degree of crystallinity than wax or natural fats and oils.

The tobacco sheet may contain liquid sugar. Liquid sugar is sugar in liquid form. When the tobacco sheet contains liquid sugar, it not only reduces the unpleasant sensation during smoking but also enhances the sweetness sensation. From this perspective, the liquid sugar content is preferably 3 to 10% by mass, more preferably 5 to 8% by mass, based on the dry matter content of the tobacco composition.

The tobacco sheet may contain a natural plant-based flavoring. When the tobacco sheet contains a natural plant-based flavoring, it not only reduces unpleasant sensations but also enhances the sweetness sensation. From this perspective, the content of the natural plant-based flavoring is preferably 0.5 to 3 mass% and more preferably 2 to 3 mass% per dry substance amount in the tobacco composition. Natural plant-based flavorings known in the tobacco field can be used, but licorice is preferred in the present invention. Licorice is a sweetener derived from Glycyrrhiza glabra, a member of the Glycyrrhiza genus of the Leguminosae family.

The amount of nicotine contained in the tobacco sheet in this embodiment is not limited, but in one embodiment, it can be 2% by mass or more per dry substance amount of the tobacco sheet. Generally, as the amount of nicotine increases, the unpleasant sensation when smoking tends to increase. However, in this embodiment, as described above, the unpleasant sensation is reduced, and therefore the effect of this embodiment is more pronounced when the amount of nicotine is within the above range. The upper limit of the nicotine amount is not limited, but in reality it is 3% by mass or less.

In another embodiment, the amount of nicotine can be 1.5% by mass or less. A nicotine amount within this range can provide a milder smoking flavor. There is no lower limit to the amount of nicotine, but in reality it is 0.1% by mass or more. The nicotine contained in the tobacco sheet may be derived from the tobacco raw material or from other components.

The tobacco sheet in this embodiment may contain the aerosol-generating agent described above. The amount of the aerosol-generating agent is preferably 12% by mass or less, more preferably 11% by mass or less, based on the dry mass of the tobacco sheet. The lower limit is not limited and may be 0% by mass, but is preferably 1% by mass or more. If the amount of the aerosol-generating agent exceeds the upper limit, it may be difficult to manufacture the sheet, and if it is less than the lower limit, the perceived smoke intensity may be reduced.

When a tobacco sheet contains a binder, the strength of the sheet is improved. A binder is an adhesive that bonds fibers together, etc. Binders known in the art can be used. Examples of binders include thickening polysaccharides such as gums, modified cellulose, and modified starch. The amount of binder is adjusted appropriately depending on the application, but can be, for example, approximately 1 to 10% by mass per dry substance of the tobacco sheet.

The tobacco sheet in this embodiment can be manufactured by any method. For example, when preparing the mixture, a saturated fatty acid-based additive can be mixed to form a blended mixture, and the sheet can be manufactured using the method described above. In this case, it is preferable to use a powdered saturated fatty acid-based additive and mix it so that the powder state is maintained. The tobacco sheet manufactured in this manner has good dispersibility of the aerosol-generating agent. Good dispersibility means that the saturated fatty acid-based additive is uniformly dispersed. The mixing process is preferably carried out at or below the melting point of the saturated fatty acid-based additive. For example, this process can be carried out at 10 to 50°C.

The mixture (also referred to as "slurry") containing the saturated fatty acid-based additive is preferably produced by a method comprising the following steps.
A step of mixing the tobacco raw material or fibrous tobacco material, a saturated fatty acid-based additive that is partly or entirely in powder form, and a medium so that the powder remains in a powder state to form a slurry.

In this method, the slurry is prepared while the saturated fatty acid-based additive remains in a powder state. This improves the dispersibility of component (B) when the resulting compact is formed. The size of the powder is as described above. "The saturated fatty acid-based additive remains in a powder state" means that some or all of the additive remains in a powder state.

Vehicles include water and hydrophilic organic solvents, but water is the most preferred medium for ease of handling.

This method first involves turning materials that are solid at room temperature into powder by grinding or other methods, and then mixing these to obtain a powder mixture. Meanwhile, a material that is liquid or pasty at room temperature, such as a medium, is mixed to obtain a liquid mixture. It is preferable to then include a step of mixing the powder mixture and the liquid mixture.

To ensure good dispersion of the powdered saturated fatty acid additive in the medium, the viscosity of the slurry at 25°C is preferably 100,000 to 200,000 (mPa·s). Viscosity is measured using a Brookfield DV-I prime viscometer with a No. LV4 spindle at 1.0 rpm.

[Third Aspect]
In this embodiment, the tobacco-containing segment (hereinafter also simply referred to as "tobacco segment") comprises paper or paper containing an aerosol-generating agent. An overview of a tobacco segment in this embodiment is shown in Figure 4A. The tobacco segment 20A comprises a tobacco filler 21 and a wrapper 22 wrapped around it. The tobacco filler 21 comprises the tobacco sheet T and paper P. In this figure, the tobacco sheet T is in the form of a strand obtained by cutting it, and the paper P is also in the form of a strand. The strand may also be obtained by cutting a sheet in which the tobacco sheet T and the paper P are laminated together. Note that in the figures explaining this embodiment, the corrugated shape of the tobacco sheet T is omitted from the illustration.

Figure 4B shows an embodiment in which a sheet-like tobacco filler 21 is filled spirally into a wrapper 22. The sheet-like tobacco filler 21 may be a sheet obtained by laminating a tobacco sheet T and paper P, or may be a sheet obtained by joining the sides of a tobacco sheet T and paper P together or at portions near the sides.

Figure 4C shows an embodiment in which a sheet-like tobacco filler 21 is folded and filled into a wrapper 22. The sheet-like tobacco filler 21 may be a sheet obtained by laminating a tobacco sheet T and paper P, or may be a sheet obtained by joining the sides of a tobacco sheet T and paper P together or at portions near the sides.

Figure 4D shows a mode in which shredded tobacco filler 21 is filled into a wrapper 22. This figure shows a mode in which shreds obtained from a tobacco sheet T and shredded paper P are prepared and then filled. The shreds may also be obtained by cutting a sheet in which tobacco sheet T and paper P are laminated together.

Figure 4E shows an embodiment in which a sheet-like tobacco filler 21 is compressed lengthwise and widthwise to form a roll, which is then filled into a wrapper 22. The sheet-like tobacco filler 21 may be a sheet obtained by laminating a tobacco sheet T and paper P, or may be a sheet obtained by joining the sides of a tobacco sheet T and paper P together or at portions near the sides.

(1) Paper (1-1) Aspect 3-1 In aspect 3-1, the tobacco segment includes a tobacco sheet and paper having a total lignin and hemicellulose content of 0.1 to 10% by mass as a filler. The filler is a filler for the tobacco segment. Lignin is a high molecular weight phenolic compound found in wood, etc. Hemicellulose is an insoluble polysaccharide found in cell walls. When the total amount is within this range, unpleasant odors (such as fibrous odors) during smoking can be reduced. In other words, this aspect has the effect of diluting the flavor and aroma without significantly impairing the original flavor and aroma. From this perspective, it is preferable that the upper limit of the total lignin and hemicellulose content be 9.0% by mass or less.

Lignin and hemicellulose are measured by known methods, but in the present invention, they are preferably measured by the following method.
[Quantitative determination of hemicellulose]
1) The paper is subjected to solvent extraction using water as a solvent, and the residue is separated. The residue is then frozen and crushed using liquid nitrogen or the like to obtain Sample A.
2) Sample A is reacted with an enzyme and the reaction product is collected.
3) The reaction product is hydrolyzed, and the absorbance of the hydrolyzate is measured at a wavelength of 490 nm to quantify the hemicellulose.

Step 1) can be carried out using, for example, a Thermo Scientific ^™ Dionex ^™ ASE ^™ Accelerated Solvent Extraction System (model number: ASE-350).

Specifically, step 2) can be carried out as follows.
50 mg of sample A was placed in a screw bottle, and 8.5 ml of ultrapure water (ML-Q water) and 0.5 ml of pancreatin solution were added. The mixture was shaken at 40°C and 125 rpm for 16 hours. The pancreatin solution was prepared by adding 8 g of pancreatin to 100 ml of 0.1 M phosphate buffer (pH 6.4), stirring for 1 hour, and then centrifuging at 8000 rpm for 30 minutes to obtain the supernatant. The sample liquid was then transferred to a 15 ml centrifuge tube using ML-Q water, centrifuged at 8000 rpm for 15 minutes, and the supernatant was removed. This washing process was repeated three times. After washing, 10 ml of 5% aqueous sulfuric acid solution was added, and hydrolysis was carried out at 100°C for 2.5 hours. After the hydrolysis reaction was complete, the sample was allowed to cool to room temperature. The precipitate was then filtered off, and the filtrate was collected in a 250 ml volumetric flask. The residue on the filter paper was thoroughly washed with ML-Q water and the volume was adjusted to 250 ml. This solution was used as the sample for hemicellulose measurement. 500 μl of the sample was transferred to a 20 ml test tube, and 500 μl of 5% aqueous phenol solution and 2.5 ml of concentrated sulfuric acid were added. The mixture was vigorously stirred for 10 seconds. The sample was left at room temperature for 20 minutes or more, and the absorbance was measured at a wavelength of 490 nm using a spectrophotometer to quantify the hemicellulose.

[Quantitative determination of lignin]
i) The sample A is prepared.
ii) Sample A is refluxed in an aqueous acid solution, and the sample after refluxing is filtered.
iii) The filtered sample is dried and then weighed to determine the amount of lignin.

Steps ii) and iii) can be specifically carried out as follows.
100 mg of sample A was placed in a screw bottle, 4 ml of 72% sulfuric acid was added, and the sample was completely immersed in the sulfuric acid and shaken at 30°C and 200 rpm for 4 hours. Next, 157.2 ml of ultrapure water (ML-Q water) was added so that the sulfuric acid concentration after dilution was 4%, and the mixture was transferred to an eggplant flask and heated to reflux in an oil bath at 110°C for 2 hours. After allowing to cool to room temperature, the mixture was filtered, dried in a rotary oven, and weighed.

The density of the paper used in this embodiment is preferably 0.05 to 0.8 (g/cm ³ ), and more preferably 0.1 to 0.6 (g/cm ³ ). The density is measured by a known method, but is preferably calculated by the following formula.
Density (g/cm ³ ) = weight (g) / area (cm ² ) / thickness (cm)

The content of the paper used in this embodiment is preferably 5 to 70% by mass, more preferably 10 to 50% by mass, and even more preferably 15 to 40% by mass, relative to the dry mass of the tobacco sheet. When the paper content is within this range, the flavor and aroma can be diluted to an appropriate level without impairing the original flavor and aroma. In one embodiment, the dry mass is the mass of the residue remaining after drying the tobacco sheet at 100°C for 5 hours.

The paper used in this embodiment is not limited as long as the total content of lignin and hemicellulose is within the above range. For example, tobacco paper such as wrappers, and printing paper such as high-quality printing paper and medium-quality printing paper can be used. However, from the perspective of suppressing the generation of unpleasant odors, uncoated paper or lightly coated paper is preferable. Furthermore, the paper used in this embodiment may or may not contain an aerosol-generating agent, as described below. The amount may be within the range described in embodiment 3-2, or may be in a range other than this.

(1-2) Aspect 3-2 In Aspect 3-2, the tobacco segment includes a tobacco sheet and paper containing an aerosol-generating agent as fillers. The aerosol-generating agent is a material that vaporizes when heated and cools to generate an aerosol, or generates an aerosol by atomization. In this aspect, the use of paper containing an aerosol-generating agent provides the effect of diluting the flavor and aroma without reducing the amount of smoke. The aerosol-generating agent can be any of those described above. The amount is preferably 3 to 20% by mass, more preferably 5 to 15% by mass, based on the dry weight of the paper. If the amount of aerosol-generating agent exceeds the upper limit, stains may occur on the tobacco segment, while if it is below the lower limit, the perceived smoke intensity may be reduced. The aerosol-generating agent can be added to the paper by impregnation, spraying, or the like.

The content of the paper to which the aerosol generating agent has been added is preferably 5 to 75% by mass, more preferably 10 to 50% by mass, and even more preferably 15 to 40% by mass, relative to the dry matter content of the tobacco sheet.

The paper used in this embodiment is not limited and may be the paper described in embodiment 3-1. The density of the paper used in this embodiment before the addition of the aerosol generating agent may be within the range described in embodiment 3-1, or may be within a different range. Furthermore, the amount of lignin and hemicellulose contained in the paper used in this embodiment is not limited and may be within the range described in embodiment 3-1, or may be within a different range.

(1-3) Shape, etc. In any embodiment, the shape of the paper is not limited, as long as it is a shape that can be easily mixed with the tobacco sheet. In one embodiment, the paper is in the form of a sheet, shreds, or strands. In a preferred embodiment, the paper and the tobacco sheet have the same shape, and in the most preferred embodiment, shredded paper and shredded tobacco sheet are used.

The paper may also contain fragrances commonly used in the field, such as menthol.

Specific examples of this embodiment are described below, but the present invention is not limited to these.

[Example 1]
Tobacco lamina (leaf tobacco) was dry-milled using a Hosokawa Micron ACM machine to obtain tobacco powder. The cumulative 90% particle size (D90) of the volume-based particle size distribution of the tobacco powder was measured by dry laser diffraction using a Mastersizer (product name, manufactured by Spectris Co., Ltd., Malvern Panalytical Division), and was found to be 200 μm.

Tobacco sheets were produced using the tobacco powder as the tobacco raw material. Specifically, 70 parts by weight of the tobacco raw material, 12 parts by weight of glycerin as an aerosol-generating agent, 4 parts by weight of powdered carboxymethyl cellulose as a first molding agent, 1 part by weight of water-swollen carboxymethyl cellulose as a second molding agent, 5 parts by weight of fibrous pulp as a reinforcing agent, and 8 parts by weight of cocoa powder as a flavoring were mixed and kneaded in an extruder. The kneaded mixture was formed into a sheet using two pairs of metal rolls to obtain a rolled product. A noodle-making rotary roll blade was pressed against the rolled product to cut it into strips and impart a corrugated shape. The product was then cut into 20 mm lengths and dried to obtain tobacco sheets measuring 20 mm in length and 0.8 mm in width. The thickness cross-section of the tobacco sheet had the cross-sectional shape shown in Figure 1.

The resulting tobacco sheets were measured for swelling. Specifically, the tobacco sheets were left in a conditioned room at 22°C and 60% humidity for 48 hours, and then the swelling was measured using a DD-60A (trade name, manufactured by Borgwald). 15 g of tobacco sheet was placed in a cylindrical container with an inner diameter of 60 mm, and compressed for 30 seconds under a 3 kg load to determine the volume. The results are shown in Table 1. Note that in Table 1, the swelling is expressed as the percentage increase in swelling relative to the reference value, which is the value of Comparative Example 1 described below.

[Comparative Example 1]
A rolled product was produced in the same manner as in Example 1. It was then cut into strips using multiple ring-shaped rotary blades. It was further cut into strips of 20 mm length, yielding a tobacco sheet with no corrugated shape, measuring 20 mm in length and 0.8 mm in width. The resulting tobacco sheet was measured for bulk expansion in the same manner as in Example 1. The results are shown in Table 1.

As can be seen from Table 1, the tobacco sheet of Example 1, which is the tobacco sheet of this embodiment, has improved swelling properties compared to the tobacco sheet of Comparison Example 1, which does not have a corrugated shape.

[Reference Example 1a]
1. Preparation of smoking composition sheet A tobacco sheet (smoking composition sheet) manufactured by a known papermaking method was prepared. The tobacco sheet was packed into a wrapper to form a smoking segment, and a non-combustion heating flavor inhaler shown in Figure 2 was prepared.

2. Preparation of fructan- or fructose-containing smoking composition sheets 10 g of inulin-type fructan (Fuji Nippon Seito Co., Ltd., product name Fuji FF) was added to 90 g of a mixture of propylene glycol and water (propylene glycol:water = 1:9 (mass ratio)) and mixed to obtain a solution of inulin-type fructan. Tobacco sheets similar to those described in 1 above were then prepared, and the inulin-type fructan solution was added using a syringe so that it was distributed throughout the tobacco sheet, thereby obtaining sheets with an inulin-type fructan content of 0.5, 1.0, 2.0, 3.0, or 3.5% by mass relative to the entire smoking composition sheet (containing inulin-type fructan) after addition.

A fructose solution was also obtained by adding 10 g of fructose (manufactured by Happo Shokusan Co., Ltd., product name: Fructose) to 90 g of a mixture of propylene glycol and water (propylene glycol:water = 1:9 (mass ratio)) and mixing. Tobacco sheets similar to those described in 1 above were then prepared, and the fructose solution was added using a syringe so that it was distributed throughout the tobacco sheet, yielding sheets with a fructose content of 0.5, 1.0, 2.0, 3.0, or 3.5% by mass relative to the entire smoking composition sheet (containing fructose).

The fructan-containing smoking composition sheet or fructose-containing smoking composition sheet obtained as described above was packed into a wrapper to form a smoking segment, and a non-combustion heating type flavor inhaler shown in Figure 2 was prepared.

The inulin-type fructan is a type of fructan, and a smoking composition sheet containing an inulin-type fructan corresponds to an example of the present application. On the other hand, fructose is a type of monosaccharide, and a smoking composition sheet containing fructose corresponds to a comparative example of the present application.

3. Evaluation of Flavor and Flavor Inhibition Each non-combustion heating type flavor inhaler prepared as described in 1 or 2 above was installed in a non-combustion external heating type smoking system shown in FIG.
For each flavor inhaler prepared in this way, 10 well-trained panelists evaluated the flavor and the sense of flavor inhibition. In this example and comparative example, "flavor" refers to a flavor that combines the flavor derived from tobacco and the sweet flavor derived from inulin-type fructan or fructose.
The flavor and flavor inhibition of each smoking test cigarette was evaluated by each panelist using the five-point scale shown in Table 1a below, with the average score of the 10 panelists being calculated. In the scale shown in Table 1a below, a score of 3 is given for a score that is equivalent to a sheet that does not contain inulin-type fructan or fructose. When the average value had a value with two decimal places, the score was calculated by rounding off the value to the nearest tenth. The evaluation results are shown in Tables 2a and 3a and FIG. 5.

As described above, the smoking composition sheet containing inulin-type fructan corresponds to an example of the present application, while the smoking composition sheet containing fructose corresponds to a comparative example of the present application.

The results in Table 2a and Figure 5 show that as the content of inulin-type fructans increases, the value of aroma taste inhibition decreases, and aroma taste inhibition can be suppressed. In particular, when the content of inulin-type fructans is 3.0% by mass or more, the aroma taste inhibition value is 1, indicating that aroma taste inhibition can be suppressed extremely strongly. Thus, it was found that a higher content of inulin-type fructans is preferable in terms of suppressing aroma taste inhibition. On the other hand, it was found that as the content of inulin-type fructans increases, the flavor tends to decrease. When emphasis is placed on flavor, a flavor value of 1.5 or more is desirable. Therefore, from the perspective of achieving both flavor and the effect of suppressing aroma taste inhibition, it was found that the content of inulin-type fructans is preferably 0.5 to 3% by mass.

On the other hand, the results in Table 3a and Figure 5 show that the addition of fructose also has a certain effect in suppressing the perceived aroma and taste inhibition. However, compared to the inulin-type fructans shown in Table 2a and Figure 5, fructose was found to have a low and insufficient effect in suppressing the perceived aroma and taste inhibition.

Furthermore, regarding fructose, panelists commented that the aroma and flavor inhibition effect increased toward the latter half of smoking (the effect of suppressing the aroma and flavor inhibition did not last long). Therefore, as shown in Reference Example 2a below, a comparative experiment was conducted to examine the duration of the aroma and flavor inhibition effect of inulin-type fructan and fructose.

[Reference example 2a]
1. Evaluation of the durability of the effect of suppressing the sense of flavor and taste inhibition A non-combustion heating type flavor inhaler prepared in the same manner as in "2. Preparation of fructan or fructose-containing smoking composition sheet" in Reference Example 1a above was installed in the non-combustion external heating type smoking system shown in Figure 3 .
For each flavor inhaler prepared in this way, 10 well-trained panelists evaluated the duration of the flavor taste inhibiting effect. The evaluation of the duration of the flavor taste inhibiting effect of each smoking test roll was carried out by each panelist evaluating the flavor taste inhibiting effect up to the latter half of smoking and the absence of any lingering flavor taste inhibiting effect after smoking according to the 5-point scale in Table 4a below, and calculating the average value of the 10 panelists. If the average value has a value to one decimal place, the score is calculated by rounding off to one decimal place.
In the criteria of Table 4a below, when evaluating the durability of the effect of suppressing the aroma and taste inhibition caused by differences in the content of inulin-type fructan, a sheet that is equivalent to a sheet containing 2.0% by mass of fructose is given a rating of 3. Also, when evaluating the durability of the effect of suppressing the aroma and taste inhibition caused by differences in the content of fructose, a sheet that is equivalent to a sheet containing 2.0% by mass of inulin-type fructan is given a rating of 3.
The evaluation results are shown in Tables 5a and 6a and FIG.

The results in Table 5a and Figure 6 show that inulin-type fructans, at any content of 0.5 to 3.5% by mass, have a superior sustained effect in suppressing the unpleasant aroma and taste compared to the comparative fructose at 2.0% by mass.
Furthermore, the results of Table 6a and Figure 6 show that fructose, at any content of 0.5 to 3.5% by mass, has a less lasting effect of suppressing the aroma and taste inhibition sensation than the comparative inulin-type fructan at 2.0% by mass.
Inulin-type fructans undergo a thermal decomposition process before developing a sweet flavor through the caramelization reaction, which is thought to result in a slow, long-term development of the sweet flavor. On the other hand, fructose develops a sweet flavor in a short time through the caramelization reaction. Since the sweet flavor suppresses the flavor-inhibiting sensation, it is thought that the difference in the development time of the sweet flavor results in a difference in the duration of the effect of suppressing the flavor-inhibiting sensation.
From the above results, it was confirmed that inulin-type fructans have a longer-lasting effect of suppressing the unpleasant aroma and taste sensation than fructose.

From the above, it was found that the tobacco material of this example continuously suppresses the aroma and taste inhibition from the early to late stages of smoking (has excellent durability of the aroma and taste inhibition effect).

[Reference example 1b]
A paper-made tobacco sheet was prepared as component (A). The sheet contained tobacco material and 15% by mass of vegetable glycerin as an aerosol-generating agent. The saturated fatty acids shown in Table 1b were prepared as component (B) and sprayed onto the sheet. The amount of component (B) added per dry mass of the tobacco composition (total of the paper-made tobacco sheet and component (B)) is as shown in Table 1b. For example, in Example A1, the amount of octanoic acid added per dry mass of the tobacco composition was 1.0% by mass.

After drying the sheet, multiple slits were made in the sheet and the sheet was rolled up to obtain a tobacco rod. The longitudinal direction of the slits was parallel to the longitudinal direction of the tobacco segments. The tobacco rod was used to manufacture a non-combustion heating tobacco flavor inhaler having the structure shown in Figure 2. The lengths of each segment were as follows:
Tobacco segment: 12 mm
Center hole: 8mm
Paper tube: 20mm
Acetate filter: 40 mm
A smoking test was carried out by heating the non-combustion heating type tobacco flavor inhaler under the following conditions using a hollow cylindrical heater having an outer diameter of 3.2 mm and an inner diameter of 1.3 mm.
Voltage: applied voltage set to 3.0 V Temperature profile: constant at 320°C Preheating time (before smoking begins): after inserting the heater into the winding, heat for 30 seconds. The test was conducted by 10 well-trained panelists using the Visual Analog Scale (categorical scale) method, with a non-combustion heating tobacco flavor inhaler manufactured without adding component (B) (see the reference comparative example below ) as a comparison. The results are shown in Table 1b. A lower score difference indicates less discomfort.

[Reference Comparative Example 1b]
A non-combustion heating type tobacco flavor inhaler was produced in the same manner as in Reference Example 1b, except that component (B) was not used.

[Reference example 2b]
The following materials were prepared:

[Quantitative determination of hemicellulose]
1) The paper was subjected to solvent extraction (solvent: water) using a Thermo Scientific ^™ Dionex ^™ ASE ^™ high-speed solvent extraction system (model number: ASE-350) to separate the residue. The residue was freeze-pulverized using liquid nitrogen or the like to obtain Sample A.
2) 50 mg of sample A was placed in a screw bottle, and 8.5 ml of ultrapure water (ML-Q water) and 0.5 ml of pancreatin solution were added. The mixture was then shaken at 40°C and 125 rpm for 16 hours. The sample liquid was then transferred to a 15 ml centrifuge tube using ML-Q water, centrifuged at 8000 rpm for 15 minutes, and the supernatant was removed. This washing process was repeated three times. After washing, 10 ml of 5% aqueous sulfuric acid solution was added, and hydrolysis was carried out at 100°C for 2.5 hours. After completion of the hydrolysis reaction, the sample was allowed to cool to room temperature. The precipitate was then filtered, and the filtrate was collected in a 250 ml measuring flask. The residue on the filter paper was thoroughly washed with ML-Q water and then the volume was adjusted to 250 ml. This solution was used as the sample for hemicellulose measurement.
3) 500 μl of the sample was transferred to a 20 ml test tube, and 500 μl of 5% aqueous phenol solution and 2.5 ml of concentrated sulfuric acid were added, followed by vigorously stirring for 10 seconds. The sample was left at room temperature for 20 minutes or more, and then the absorbance was measured at a wavelength of 490 nm using a spectrophotometer to quantify the hemicellulose.
