Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a combination chewing gum that can be enjoyed by drawing letters or pictures on the surface of the gum, and a method for producing the same. [Prior Art] In general, chewing gum is not interesting if the color of the raw material is the same, 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 the surface of the chewing gum with food pigments. [Problems to be Solved by the Invention] By the way, with the wide variety of chewing gums on the market these days, simply being colored in a unique color or pattern has little appeal to consumers. Therefore, it is desired to provide a new type of chewing gum that allows consumers to draw designs on the chewing gum and enjoy the joy of creativity. As mentioned above, in order for consumers to draw designs on the chewing gum themselves, since normal pigments are in the form of aqueous solutions, it is necessary to paint on the surface of the chewing gum with colored water, or to add special pigments to the chewing gum in advance. One possible method is to partially color the chewing gum by applying water to the surface of the chewing gum and then painting the chewing gum with water. However, even if water or colored water is applied to the chewing gum surface, the gum structure is so dense that the water does not penetrate the gum surface and is repelled, resulting in poor decoration. The present invention has been made in view of the above circumstances, and aims to provide a combination chewing gum that allows users to enjoy drawing letters and pictures on the surface of the gum, and a method for producing the same. [Means for Solving the Problems] In order to achieve the above object, the present invention comprises the following chewing gum (A) and solution (B), and brings the solution (B) into contact with the chewing gum (A). The first gist is a chewing gum combination that can change the color tone of the chewing gum (A) at the contact part and create a color pattern, and (A) a chewing gum that contains a gum base, a carbohydrate component, a moisturizing component, and a pigment. The chewing gum contains as the carbohydrate component hydrated crystalline maltose formed by hydrating anhydrous crystalline maltose in the chewing gum tissue, and also contains a pigment whose color tone changes depending on pH as the pigment. (B) PH of the contact area due to contact with chewing gum (A)
PH adjustment solution that changes the Gum base and anhydrous crystalline maltose (e.g. JP-A-61
A chewing gum raw material containing crystalline α-maltose (described in Publication No. 35800), a moisturizing component, and a pigment whose color tone changes depending on the pH is prepared, and after forming the above chewing gum raw material into a predetermined shape, the molded chewing gum is A second method for producing a combination chewing gum comprising a chewing gum production process of converting anhydrous crystalline maltose into water-containing crystalline maltose, and a pH adjustment solution production process of preparing a pH adjustment solution having a predetermined pH and then sealingly filling it into a predetermined container. The summary is as follows. That is, the combination chewing gum of the present invention is
A special chewing gum (A) that contains hydrated crystalline maltose, which is formed by hydrating anhydrous crystalline maltose in the chewing gum tissue, as a carbohydrate component, and contains a pigment whose color tone changes depending on the pH.
and the above-mentioned chewing gum and the contact area
This is combined with a PH adjustment solution (B) that changes the PH.The structure of the chewing gum is improved to be more porous due to the presence of the above-mentioned hydrated crystalline maltose, making it highly absorbent. This immediately penetrates and changes the pH of the area, changing the color tone of the pigment contained in the chewing gum and creating a vivid color pattern. This is a major feature of the present invention. Next, the present invention will be explained in detail. The combination chewing gum of the present invention comprises the above-mentioned special chewing gum (A) and a solution (B), and when the chewing gum (A) is set to be acidic, an alkaline solution (B) is combined with the chewing gum (A). When setting A) to be alkaline, an acidic solution (B) is combined, and the PH of the chewing gum (A) in the contact area is changed by contact with the solution (B). When the above-mentioned chewing gum (A) is set to be acidic, for example, the chewing gum (A) is made as follows. That is,
First, the gum base is kept warm at 40-50°C, put into a mixer (kneader), moisturizing ingredients and anhydrous crystalline maltose are added, and thoroughly kneaded. Then, when the whole mixture is almost uniformly mixed, a flavoring agent, a color that does not develop color on the acidic side, such as Food Red No. 104, and an acidulant such as citric acid are added, and the mixture is sufficiently kneaded until a uniform smoothness is obtained. Chewing gum is thus obtained. Next, the above-mentioned chewing gum is formed into a plate shape like a normal sheet gum by rolling, and then left to stand for 5 days under high humidity, for example, in an atmosphere with a humidity of 80%. 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 chewing gum (A). Also, if water is added instead of a moisturizing ingredient, molded chewing gum can
Even at room temperature, chewing gum (A) is formed by the movement of water in the tissue and the transformation of anhydrous crystalline maltose into water-containing crystalline maltose. The above-mentioned chewing gum (A) has expanded due to 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 swelling is
Although it can be easily identified with the naked eye, it can also be confirmed by actual measurement. That is, the theoretical weight increase rate when changing from anhydrous crystalline maltose to hydrous crystalline maltose is 5 to 7% by weight, and the actual measured value is also approximately equal to this. Therefore, it can first be confirmed that all the anhydrous crystalline maltose in the raw material has changed to hydrous crystalline maltose. On the other hand, when the volume of the molded chewing gum was measured before and after being left standing under the above-mentioned high humidity, it was found that the volume of the molded chewing gum increased by about 150% by volume. Therefore, when comparing the weight change and the volume change, it can be seen that the volume change is larger, and as a result, the density of the molded chewing gum becomes smaller. Due to this,
It can be confirmed that the chewing gum has expanded. The above volume increase and swelling can be considered as follows. That is, the shaped chewing gum before being hydrated has a dense structure as schematically shown in FIG. In the figure, 11 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. That is, the hydrated crystalline maltose 11a whose volume has increased due to water content creates voids 13 between it and other gum components 12, destroying the dense structure and forming a porous structure. In addition, while the volume ratio of normal chewing gum is about 0.75 cm ³ /g, the volume ratio of the chewing gum (A) of the present invention is 0.85 cm ³ /g or more, preferably 0.85 to 1.5 cm ³ /g. and the two are distinct. As described above, since the chewing gum (A) of the present invention has voids inside and is swollen, water easily penetrates into it, and it exhibits significantly higher water absorption than conventional chewing gum. In the above production method, the moisturizing ingredients used include sugar alcohols, glycerin, starch syrup, etc., but water may also be simply added. Among them,
Sorbit and glycerin are preferred. These may be used alone or in combination. The above-mentioned sorbitol is usually used as a 70% by weight aqueous solution, and is preferably used in an amount of 15% by weight or less based on the total amount of chewing gum. This is because if the content exceeds 15% by weight, the chewing gum becomes sticky and moldability tends to deteriorate. Furthermore, when using the above-mentioned glycerin, it is preferable to use it in an amount of 15% by weight 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% by weight aqueous solution, and preferably in an amount of 20% by weight or less based on the total amount of chewing gum. In the above manufacturing method, the type of gum base used is not particularly limited, but it is preferably used in an amount of 15 to 85% by weight based on the total amount of chewing gum. This is because if it is less than 15% by weight, the sticky texture typical of chewing gum cannot be obtained when eaten, and if it exceeds 85% by weight, the moldability of the gum tends to deteriorate. Furthermore, in the above manufacturing method, the anhydrous crystalline maltose used is 30 to 80% by weight based on the total amount of chewing gum.
Of these, 40 are suitable for use in terms of effectiveness.
It is particularly optimal to use ~75% by weight. In addition,
A portion 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 types (weight ratio)
is preferably 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. In addition, in the above manufacturing method, the dye used must have a color tone that changes depending on the pH. In other words, the chewing gum (A) is colored (or uncolored in some cases) by this pigment, which will be described later.
The contact area caused by contact with the PH adjustment solution (B)
Due to this change, the color tone of the contact area changes compared to other parts (in some cases, a new color appears), and a 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 (A) 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 (A). Therefore, the PH of the contact area of the chewing gum (A) changes due to the instantaneous contact between the two, and since the pigment in the chewing gum (A) is a pigment whose color tone changes depending on the change in PH, the chewing gum (A) ), the color tone of the contact area with the above PH adjustment solution changes,
A colored pattern appears on the chewing gum (A). Therefore, it is extremely novel in that the consumer can not only enjoy the chewing gum properties of this chewing gum, but also enjoy the creative enjoyment of drawing letters, patterns, etc. on the surface of the chewing gum before eating. Next, the present invention will be described in conjunction with examples and comparative examples. Example 1 First, the following raw materials were prepared in the following proportions, and chewing gum (A) was obtained according to the above manufacturing method. This is white. Gum base: 20% by weight Anhydrous crystalline maltose: 71.9 Glycerin: 3 Water: 3 Flavor: 0.8 Acidulant: 1 Red No. 104 5% by weight aqueous solution: 0.3% by weight Next, add a 10% by weight aqueous solution of baking soda. This was used as the PH adjustment solution (B). This is transparent. When a picture was drawn on the surface of the chewing gum (A) with the solution (B), the drawn locus instantly turned red, and a red picture appeared on the white surface of the chewing gum (A). Comparative Example 1 The following raw materials were kneaded in the following proportions according to a conventional method, and after cooling, a chewing gum (A') formed into a plate was obtained. Gum base: 20% by weight Sugar: 65.9 〃 Water candy: 12 〃 Flavor: 0.8 〃 Acidulant: 1 〃 Red No. 104 5% by weight aqueous solution: 0.3 〃 On the surface of the above chewing gum (A'), A picture was drawn with the solution (B) used. At this time, the solution (B) was repelled by the surface of the chewing gum (A') and did not penetrate well, and the traces drawn were not sufficiently colored. Examples 2 to 7 The dyes shown in Table 2 below were used as dyes.
Other than that, chewing gum (A) was obtained in the same manner as in Example 1. The color of the chewing gum (A) is as shown in Table 2, and when a picture is drawn on the surface with the solution (B) used in Example 1, the drawn trajectory changes color instantly and can be distinguished from the background. A pattern has emerged. The colors of the designs are also shown in Table 2.
