Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a new type of combination chewing gum in which a color pattern emerges from the surface of a plain chewing gum, and a method for producing the same. [Prior Art] Generally, chewing gum is not interesting if it is kept in the color of the raw material, so it is colored with a color or pattern that matches the product image. Such coloring is mainly carried out by mixing pigments into raw materials and molding the mixture to color the entire product, or by printing food pigments on the surface of the chewing gum. However, simply being colored with a unique color or pattern has little appeal to consumers, so recently, chewing gum that changes color due to the elution of acid or alkali when chewing in the mouth, and chewing gum that has pigments on the surface of the chewing gum, have become popular. Chewing gum that is printed with some kind of design and covered with opaque candy, etc., so that the design appears as the candy, etc. dissolves in the mouth, so as to arouse interest through visual changes. There are many innovative chewing gums on the market. [Problems to be Solved by the Invention] However, the above-mentioned color-changing chewing gum and chewing gum in which the design appears later use saliva in the mouth to change the color, so the consumer himself or herself is responsible for the change. If you want to enjoy it, you have to take the chewing gum out of your mouth or look in a mirror at the chewing gum in your mouth, which is quite inconvenient. Therefore, instead of using saliva, it is possible to use a PH adjustment solution or the like and apply it to the surface of the chewing gum to change the color of the chewing gum or to make a pattern appear. However, the reality is that the gum structure is so dense that water does not penetrate the gum surface and is repelled, making it difficult to properly change the color or create a pattern. The present invention was made in view of the above circumstances, and provides a combination chewing gum and a method for producing the same, in which a latent pattern previously given to the chewing gum appears by simply applying a PH adjusting solution to the surface of the chewing gum without putting it in the mouth. Its purpose is to provide the following. [Means for Solving the Problems] In order to achieve the above object, the present invention provides two types of color tones that exhibit the same color tone in a normal PH range and that exhibit mutually different color tones in a specific PH range different from the above PH range. A combination chewing gum comprising a chewing gum in which the above-mentioned chewing gum components are integrally molded to form a latent pattern, and a PH adjustment solution that changes the PH of the chewing gum to reveal a color pattern, the above-mentioned two types The first gist is a combination chewing gum in which the above chewing gum ingredients are chewing gum ingredients that are obtained by subjecting chewing gum containing a gum base, anhydrous crystalline maltose, and a moisturizing ingredient to a hydration process. A chewing gum raw material containing crystalline α-maltose (described in JP-A No. 61-35800), a moisturizing component, and a pigment having a predetermined color tone and whose color tone can change in a specific PH range is prepared. , a process for manufacturing a color-changing chewing gum component a in which the above-mentioned chewing gum raw material is molded into a predetermined shape, and then anhydrous crystalline maltose in the formed chewing gum is changed into hydrated crystalline maltose; a gum base, an anhydrous crystalline maltose, a moisturizing component, and the above-mentioned color-changing chewing gum component. A chewing gum raw material containing a pigment that has the same color tone as the pigment in a and whose color tone does not change in the above specific PH range is prepared, and after molding the chewing gum raw material into a predetermined shape, anhydrous crystals in this molded chewing gum are formed. A manufacturing process of unchangeable chewing gum component b in which maltose is changed into water-containing crystalline maltose, and a die device equipped with two extrusion molding machines that supply the above-mentioned color-changing chewing gum component a and an extrusion molding machine that supplies the above-mentioned unchangeable chewing gum component b. The color-changing chewing gum component a is extracted from both extruders using a die device that extends the discharge port of the die of one extruder and coaxially disposes it inside the open end of the die of the other extruder.
and unchangeable chewing gum component b are simultaneously extruded to form a latent pattern of color-changing chewing gum component a, and the outside of the latent pattern is formed by unchangeable chewing gum component b.

The second gist is a method for manufacturing a combination chewing gum, which includes a step of manufacturing a PH adjustment solution that is hermetically filled into a container. That is, the combination chewing gum of the present invention is
Two or more types of chewing gum ingredients that form a latent pattern that can reveal a color pattern through a change in pH are produced by passing chewing gum containing a gum base, anhydrous crystalline maltose, and a moisturizing ingredient through a hydration process. A special chewing gum called Naru,
It is combined with a PH adjustment solution that changes the PH of the contact area when it comes into contact with the chewing gum, and the structure of the chewing gum is improved to be more porous through the hydration process, resulting in higher water absorption. When the conditioning solution is applied to chewing gum, it immediately penetrates and changes the pH of the applied area, causing the latent pattern of the chewing gum to appear as a clear color pattern. This is a major feature of the present invention. Therefore, in the present invention, it is sufficient that a color pattern appears as a result of a change in PH. "Two or more types of chewing gum components exhibiting different color tones" refers to combinations in which at least one chewing gum component remains colorless and at least one other chewing gum component develops color from colorless to colored, or chewing gums having the same color tone. It refers to a combination of components that change color to mutually different tones. Next, the present invention will be explained in detail. The combination chewing gum of the present invention is equipped with the above-mentioned special chewing gum and a PH adjustment solution, and when setting the chewing gum to be acidic, an alkaline PH adjustment solution is combined, and when setting the chewing gum to be alkaline, an alkaline PH adjustment solution is combined. of
As a combination of PH adjusting solutions, by applying the PH adjusting solution to chewing gum, the PH of the chewing gum at the application area is changed. For example, when the chewing gum is set to be acidic, it is manufactured as follows. That is,
First, the gum base is kept warm at 40 to 50°C, put into a mixer (kneader), moisturizing ingredients and anhydrous crystalline maltose are added, and thoroughly kneaded. Then, when the whole is mixed almost uniformly, flavoring, a pigment that does not develop color on the acidic side but develops color on the alkaline side (for example, Food Red No. 104), and an acidulant such as citric acid are added,
Color-changing chewing gum ingredient a that appears uncolored when it is kneaded thoroughly until it becomes uniformly smooth.
get. Further, in the same manner as above except that no pigment is added, an unchanged chewing gum component b which is uncolored, that is, remains colorless whether it is on the acidic side or the alkaline side is obtained. Next, the above-mentioned color-changing chewing gum component a and the above-mentioned unchanging chewing gum component b are combined to form a chewing gum in which latent patterns are formed by the color-changing chewing gum component a into a plate shape, and then the chewing gum is formed into a plate shape under high humidity, for example, at a humidity of 80°C. % atmosphere for 5 days. As a result, during the above-mentioned standing period, the anhydrous crystalline maltose in the shaped chewing gum absorbs moisture in the atmosphere and becomes hydrated crystalline maltose, yielding a special hydrated chewing gum. Furthermore, if water is added instead of a moisturizing ingredient, the shaped chewing gum becomes hydrated even under normal humidity as water in the tissue migrates and anhydrous crystalline maltose changes to hydrous crystalline maltose. The above-mentioned chewing gum is expanded by standing under high humidity and has a whitish appearance. When you pick it up with your fingers, it feels crispy and has a dry and porous feel. This expansion can be considered as follows. That is, the shaped chewing gum before being hydrated has a dense structure as schematically shown in FIG. 10. In the figure, 1
1 is anhydrous crystalline maltose, and 12 is other gum components. On the other hand, after hydration, the dense structure is destroyed, as schematically shown in FIG. 11.
That is, the water-containing crystalline maltose 11a whose volume has increased due to water content forms a void 13 between it and other gum components 12.
This creates a porous structure by destroying the dense structure. As described above, the chewing gum used in the present invention has voids inside and is swollen, so water easily penetrates into it, and it exhibits significantly higher water absorption than conventional chewing gum. The chewing gum thus obtained is normally colorless chewing gum without any color pattern, as shown in FIG. 1a. However, since the pattern shown by the broken line in the figure is formed by the color-changing chewing gum component a as the latent pattern 1, the PH range of the gum surface changes to the alkaline side by applying the PH adjusting solution described later. , 1st
As shown in FIG. b, the latent pattern 1 comes to clearly appear as a colored pattern. In the above chewing gum manufacturing method, the chewing gum is formed into a plate shape as shown in FIG. 1 by appropriately distributing and placing the color-changing chewing gum component a and the unchanged chewing gum component b on a flat surface, and then pressing. In addition to this method, for example, latent patterned chewing gum may be made into a bar shape in the same manner as Kintaro candy, and then cut. In particular, the latter method has high production efficiency and is more suitable. In the above-mentioned Kintaro candy manufacturing method, an apparatus as shown in FIG. 2 is usually used. That is, this device is equipped with an extrusion molding machine 21 that supplies the color-changing chewing gum component a and an extrusion molding machine 22 that supplies the chewing gum component b, and the discharge port 23 of the die of one extrusion molding machine 21 is extended to It is disposed coaxially inside the open end of the discharge port 24 of the die of the extrusion molding machine 22. The cross-sectional shape is as shown in Figure 3, which shows the A-A' cross section in Figure 2, and the color-changing chewing gum component a
A shape for shaping is given to the inner discharge port 23 (in this case, a spade shape). By simultaneously extruding chewing gum components a and b from this device, a bar-shaped chewing gum is obtained in which a pattern made of color-changing chewing gum component a is surrounded by unchanged chewing gum component b, like Kintaro candy. However, in the present invention, it is particularly preferable to use a device as shown in FIG. 4 instead of the above device. In other words, this device does not simply arrange the discharge ports of the two extrusion molding machines 21 and 22 coaxially, but each discharge port has an enlarged part in which the chewing gum supply channel is partially enlarged. The connecting flow path block 25 having the above-mentioned connecting flow path block 25 is connected, and new discharge ports 26 and 27 are attached to the chewing gum supply flow path of the connection flow path block 25. The arrangement of the chewing gum supply channel formed in the connection channel block 25 and the cross-sectional shape of the discharge ports 26 and 27 are as shown in FIG. . When this device is used, the enlarged portion formed in the chewing gum supply flow path absorbs variations in the amount of chewing gum supplied, which varies depending on the physical properties (mixing state, cooling state, etc.) of the chewing gum to be supplied. Components a and b are always supplied in an appropriate ratio, and the pattern does not become deformed. In the above chewing gum manufacturing method, examples of moisturizing ingredients used include sugar alcohols, glycerin, starch syrup, etc., but water may also be simply added. Among these, sorbitol and glycerin are preferred. These may be used alone or in combination. The above sorbitol is usually used as a 70% by weight (hereinafter abbreviated as "%") aqueous sorbit solution,
It is preferable to use it in an amount of 15% or less based on the total amount of chewing gum. This is because if the content exceeds 15%, the chewing gum becomes sticky and moldability tends to deteriorate. Furthermore, when using the above-mentioned glycerin, it is preferable to use it within a range of 15% or less based on the total amount of chewing gum for the same reason as above. Furthermore, when using the above starch syrup, it is usually used as a 70% aqueous solution of starch syrup, and it is preferably used in an amount of 20% or less based on the total amount of chewing gum. Further, in the above manufacturing method, the type of gum base used is not particularly limited, but it is preferably used in a range of 15 to 85% based on the total amount of chewing gum. This is because if it is less than 15%, the sticky texture typical of chewing gum cannot be obtained when eaten, and if it exceeds 85%, the moldability of the gum tends to deteriorate. Furthermore, in the above manufacturing method, it is preferable to use 30 to 80% of the anhydrous crystalline maltose based on the total amount of chewing gum, and 40 to 80% of the total amount of chewing gum is used.
It is particularly optimal to use 75%. Note that a part of the anhydrous crystalline maltose can be replaced with other sugars such as sugar, glucose, and lactose. The blending ratio of anhydrous crystalline maltose and other sugars at this time is:
Anhydrous crystalline maltose/other sugars (weight ratio)
It is preferable that it is 100/0 to 4/96, especially
It is suitable that it is 100/0 to 15/85. That is, if the blending ratio of other saccharides exceeds the above range, the gum structure will become dense like normal chewing gum, and water permeability will deteriorate. Further, in the above manufacturing method, the coloring matter used in the color-changing chewing gum component a must be one whose color tone changes depending on the pH. In other words, this pigment gives the chewing gum a latent pattern, and as the pH of the contact area changes due to contact with the PH adjustment solution described below, the color tone of the contact area changes and the latent pattern becomes apparent. The colors change and the color pattern appears. Examples of the dyes whose color tone changes depending on the pH include the dyes shown in Table 1 below.

〔Effect of the invention〕

As described above, the combination chewing gum of the present invention combines a special chewing gum that has high water absorption due to the presence of hydrated crystalline maltose and a PH adjustment solution that changes the PH of the chewing gum. The PH of the contact area of chewing gum A changes due to the contact with the chewing gum, and the color change of the color-changing chewing gum component pigments that are partially used in the above chewing gum changes color tone due to the change in PH, and the color tone of the color-changing chewing gum component that is partially used in the above chewing gum changes, causing the color tone of the color that was previously latent on the chewing gum to change. The color patterns that used to exist are starting to appear. Therefore, it is extremely novel in that the eater can not only enjoy the chewing gum properties of this chewing gum, but also enjoy the visual pleasure of seeing letters, patterns, etc. appearing on the surface of the chewing gum. Next, examples of the present invention will be described together with comparative examples.

A plate-shaped chewing gum as shown in Figure a was manufactured. Meanwhile, a 10% aqueous solution of baking soda was made and used as a pH adjustment solution. This is transparent. When the PH adjustment solution was applied to the surface of the chewing gum, a red picture appeared on the white surface of the applied end (see Fig. 1 <<b>>). [Comparative Example] The following raw materials were kneaded in the following proportions according to a conventional method, and the mixture was cooled to obtain chewing gum component c. Gum base: 20% Sugar: 65.9〃 Water Candy: 12〃 Flavor: 0.8〃 Acidulant: 1〃 Red No. 104 5% aqueous solution: 0.3〃 In addition, the following raw materials were kneaded in the following proportions according to the usual method, This was cooled to obtain chewing gum component d.

A plate-shaped chewing gum was obtained in the same manner as in Example 1 except that component b was used. The PH adjustment solution used in Example 1 was applied to the surface of the chewing gum. However, the PH adjustment solution was repelled by the surface of the chewing gum and did not penetrate well, and the pattern was hardly visible.
