Description

  The present invention effectively removes coloring matter (stain) that adheres firmly to teeth by eating and drinking food, smoking, colored substances produced by bacteria in the oral cavity, etc., and is excellent in tooth whitening effect and can also remove tongue coating. The present invention relates to a sugar-coated chewing gum composition and a method for producing a sugar-coated chewing gum.

  Various methods have been proposed for gums that remove colored substances adhering to teeth. A chewing gum composition (Patent Document 1) that can remove tooth dirt by a combination of an anionic surfactant and a nonionic surfactant, and an anionic surfactant and a nonionic encapsulated in a water-soluble polymer A soil-removing gum containing a surfactant (Patent Document 2), a silica particle, and a whitening chewing gum containing a polyphosphate (Patent Document 3) have been proposed.

  However, in these methods, the stubborn stain deposited on the tooth surface due to poor oral cleaning for a long period of time has often not been sufficiently removed.

  In addition, as a technique of a physical removal method in which an inorganic powder is blended with chewing gum, a chewing gum composition (patent document 4) in which bone mineral and tricalcium phosphate and / or hydroxyapatite are blended in a gum base contains calcium granules. Therefore, a chewing gum (Patent Document 5) excellent in texture, chewing feeling and brushing effect has been proposed. However, with these methods, it is difficult to sufficiently remove stubborn stains deposited on the tooth surface due to poor oral cleaning for a long period of time.

  Furthermore, the applicant has combined chewing gum composition (Patent Document 6) with a non-cariogenic sugar such as sugar alcohol having an average particle size of 200 to 2,000 μm and polyphosphoric acid and blended with a gum base (Patent Document 6). Although it was proposed that the effect to be removed was excellent, there was room for further improvement in the effect and cleaning feeling.

The first step comprises (A) at least one polyphosphate selected from the linear polyphosphate represented by the general formula (1) and the cyclic polyphosphate represented by the general formula (2); (B) is a step of forming a chewing gum main component with a chewing gum main component containing erythritol having an average particle size of 200 to 2,000 μm.
In order to produce a sugar-coated chewing gum with the sugar-coated chewing gum composition of the present invention, for example, first, a gum base comprising a resin for gum base as a main component, a wax, an emulsifier, a filler and the like, components (A) and (B), Add additives such as sweeteners, fragrances, colorants, softeners, taste-masking substances as necessary, and knead uniformly using a kneader at around 50 ° C., and then to an appropriate shape such as a plate or block It can cut | disconnect and a chewing gum main body (chewing gum layer) can be obtained. At this time, the mass of the chewing gum main body is preferably about 1 to 2 g.

The second step is a step of forming a sugar coating inner layer covering the chewing gum main body with a sugar coating inner layer component containing maltitol (sugar coating inner layer step).
In order to form a sugar coating layer on the chewing gum main surface, it is possible to use a sugar coating bread or a rotary pot and adopt a usual method.
The sugar coating process may be performed by any of a so-called hard sugar coating method using only edible gum and syrup, and a so-called soft sugar coating method in which a fine powder material made of powdered sugar and the syrup are alternately applied.

The sugar-coated bread or rotary hook is preferably a top-opened bottomed container that is connected to a drive motor and is attached to a rotary drive shaft that is disposed, for example, at an angle of 10 to 60 ° with respect to the vertical line. For example, FY-TS-220 manufactured by Fuji Pharmaceutical Machinery Co., Ltd. can be used. The chewing gum main body is put into the sugar-coated bread or the rotary kettle, and the sugar-coated syrup containing the sugar-coating raw material is added while the sugar-coated bread is rotated at 5 to 30 revolutions / min. When the whole is coated, a liquid component such as a powder component or an oil flavor is added and dried by blowing to form a sugar coating inner layer. Drying can be performed, for example, by supplying the powder component and spreading it over the entire coating, or by blowing after the treatment with the powder component. In the case of blowing air, the air volume is preferably 3 to 10 m ² / min. For example, drying is preferably performed so that the water content is 1 to 3%. This step is preferably repeated until the ratio of the sugar-coating layer is 20 to 30% of the entire preparation (sugar-coating chewing gum in which the chewing gum main body is coated with the sugar-coating layer).

  The third step is a step of forming a sugar coating outer layer that covers the sugar coating inner layer (sugar coating outer layer step), and a sugar coating syrup containing maltitol and sorbitol is applied to the surface of the sugar coating inner layer that covers the chewing gum main body, A sugar coating in which the inner surface of the sugar coating is coated with a sugar coating outer layer component containing maltitol and sorbitol by repeatedly applying a hot air of 30 to 35 ° C. in the wet stage and rapidly drying, and the surface is roughened Form the outer layer.

  In order to form a sugar-coated outer layer, a sugar-coated bread or a rotary kettle can be used in the same manner as described above, and an ordinary method can be adopted, and either a hard sugar-coating method or a soft sugar-coating method may be used.

In order to roughen the surface of the sugar-coated outer layer, the sugar-coating inner layer forming step with maltitol syrup is repeated, and when the ratio of the sugar-coating layer reaches 20 to 24% of the entire preparation, the following sugar-coating outer layer step may be started. preferable. In this sugar coating outer layer process, after applying the mixed syrup of maltitol and sorbitol to the surface of the sugar coating (sugar coating inner layer), the amount of air flow is preferably 10-15 m ² / min, 30 to 30 By repeatedly performing the process of applying hot air of 35 ° C., the surface can be roughened to a pear surface. It is preferable to repeat this process until the ratio of the sugar coating outer layer becomes 10 to 20% of the entire preparation.

In this case, sugar coating syrup containing 1 to 20% of sorbitol and 10 to 70% of maltitol is used for forming the sugar coating outer layer and roughening the surface, and the sugar coating liquid is repeatedly applied to the center core in the rotating coating pan. When applying, a temperature of 30 to 35 ° C., preferably around 30 ° C. is quickly put into the coating pan when the entire sugar coating inner layer of the center core (the chewing gum main body is coated with the sugar coating inner layer) is still wet with the sugar coating syrup solution. It is important to quickly dry with wind, and this causes uneven evaporation and scattering of moisture from the sugar coating syrup solution adhering to the surface of the center core. By repeating this sugar coating and drying process, Countless dome-shaped protrusions are stacked on top, and can be roughened into a satin finish with fine and rounded irregularities. The textured rough surface may have a surface unevenness of 0.01 to 1 mm, but the unevenness can be controlled by the number of times the sugar coating liquid is applied. The unevenness of the surface is 0.01 to 1 mm, and the number of times of applying the sugar coating liquid is not particularly limited, but it is preferable to repeat it until the ratio of the sugar coating outer layer becomes 10 to 20% of the whole preparation.
In addition, maltitol syrup used for a sugar coating liquid is easy to dry.For this reason, in general, when a sugar coating liquid is applied when the sugar coating liquid is applied, the maltitol syrup is quickly dried naturally and then dried with hot air. By forming the sugar coating outer layer using the sugar coating syrup solution containing maltitol and sorbitol in the above step, it is possible to rapidly dry with hot air in the wet state before the sugar coating surface is naturally dried. The surface can be roughened into a satin finish by carrying out. When the surface of the sugar-coated outer layer is not roughened and is flat, the effect of the present invention cannot be achieved.

  Further, after the sugar coating layer is formed, a further process such as polishing may be employed. For example, in the polishing process, a polishing wax is supplied into the rotary kettle and the rotary coater is rotated while the sugar coating is being rotated. It can also be performed by coating the surface of the sugar coating layer of the chewing gum with a wax. In this case, carnauba wax or candelilla wax may be used as the wax. In the present invention, the polishing and other steps are preferably performed within a range in which the textured rough surface of the sugar coating outer layer surface is not cut, and in the case of cutting, this step may be omitted.

  The sugar-coated chewing gum composition of the present invention is prepared into sugar-coated chewing gums of various shapes such as round and square, but particularly prepared in a square shape is resistant to scratches and the like from the viewpoint of appearance stability. Is preferred.

This kneaded product was cut into blocks to obtain a chewing gum main body (chewing gum layer). At this time, the mass of the chewing gum main body was set to about 1 g. Then, the chewing gum main body is put into a sugar-coated bread or a rotary pot, and while the sugar-coated bread is rotated at 10 rpm, only maltitol (fine powder) is sprinkled into 5 times and sprinkled, and then the sugar-coated inner layer is formed. The sugar coating syrup (arabic gum-containing maltitol <1> in Table 2) was applied to the chewing gum main surface and the drying process was repeated to form a sugar coating inner layer. In the case of a sugar-coated inner layer only (single layer), the step of mixing oil fragrance with the final 9 L sugar-coated inner layer syrup and drying it over the gum surface is repeated until the ratio of the sugar-coated inner layer reaches 20 to 24% of the entire preparation Ended with. In the case of having a sugar-coated outer layer, when the ratio of the sugar-coated inner layer reaches 20 to 24% of the entire preparation, a sugar-coated syrup for forming a sugar-coated outer layer (one of <2> to <5> in Table 2) is added. Repeat the process of quickly applying warm air of 30-35 ° C for 30 seconds with a wind speed of 10-15m ² / min when the surface is wet, and the ratio of sugar coating outer layer is 10-20% of the total formulation The process was repeated until a sugar-coated outer layer was formed to produce a sugar-coated chewing gum.
The sugar-coated chewing gum of the comparative example was prepared according to the above method.
