DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-adhesive chewing gum containing a gum base which does not easily adhere to dentures, floors and the like.

[0002]

2. Description of the Related Art In general, chewing gum has a specific viscoelasticity and thus easily adheres due to the interfacial force with the tooth surface. This adhesion is remarkable especially in the case of dentures such as dentures, and therefore, a person using the denture becomes a great obstacle in enjoying chewing gum. Also, after chewing the chewing gum, the chewing gum that was discarded without wrapping it in paper, if thrown away on the road, floor, etc., easily adheres, it will dry over time and it will be difficult to peel off, Removal is more difficult than in the case of adhesion to dentures. In particular,
Chewing gum is frequently thrown away in public facilities such as stations, and is becoming a social problem because it detracts from aesthetics.

In order to solve such a problem, chewing gums have been conventionally improved with a focus on prevention of adhesion to dentures. However, although all of them have an effect on adhesion to dentures, they prevent adhesion to floors. The effect is inadequate. For example, Japanese Patent Publication No. 58-6455 discloses that as an anti-toothing agent, 0.05 to 3.0% by weight based on chewing gum.
Polyglycerin fatty acid ester (2-7 glycerin)
It is disclosed that a monomer, a fatty acid having 12 to 20 carbon atoms) is added. When polyglycerin fatty acid ester is used as an anti-toothing agent, compared to conventional emulsifiers such as glycerin fatty acid ester and sucrose fatty acid ester, an anti-toothing effect is observed and a slight improvement in texture is also observed. However, roads, floors, and the like are more likely to dry out than the teeth or dentures in the mouth because they are exposed to the atmosphere, and are more likely to adhere to the teeth than in the case of teeth. Therefore, polyglycerol fatty acid d
The stell alone does not have sufficient effect of preventing adhesion to a floor material or the like.

A combination of polyglycerin fatty acid ester and another emulsifier is disclosed in Japanese Patent Application Laid-Open No. 60-6693.

0%, non-adherent chewing gum with 8-20% mineral. The emulsifier used here is a single or mixture of fatty acid monoglyceride, diglyceride, acetylated monoglyceride, triacetin, and polyglycerin fatty acid ester. However, even with this combination, although the adhesiveness to the teeth is improved, the moisturizing property of the chewing gum at the interface between the flooring material and the like and the chewing gum becomes insufficient, so that the chewing gum tends to dry and the adhesion preventing effect is hardly obtained. As described above, the conventional non-adhesive chewing gum has an effect of preventing adhesion to teeth, but does not have an effect of preventing adhesion to flooring materials and the like.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and has as its object to provide an excellent effect of preventing adhesion to not only dentures but also floor materials and the like.
Another object of the present invention is to provide a non-adhesive chewing gum having good flavor and texture.

[0006]

The above object is achieved by a non-adherent chewing gum characterized in that the gum base contains a propylene glycol fatty acid ester having 8 to 12 carbon atoms in the fatty acid moiety. .

That is, the present inventors have studied emulsifiers for chewing gum which can particularly prevent adhesion to flooring materials and the like. As a result, propylene glycol fatty acid esters having a fatty acid portion of 8 to 12 carbon atoms were obtained. It has been found that when incorporated in a gum base, the effect of preventing adhesion to a floor material or the like is significantly improved, and the present invention has been completed.

Next, the present invention will be described in detail. In the gum base of the non-adhesive chewing gum of the present invention, a propylene glycol fatty acid ester having a fatty acid portion having 8 to 12 carbon atoms (hereinafter referred to as “PG ester”) used as an antiadhesive agent is as follows: It is a lipophilic emulsifier represented by Chemical formula 1 or Chemical formula 2.

When the fatty acid of the PG ester has less than 8 carbon atoms, the hydrophilicity is enhanced, the effect of softening (plasticizing) the elastic body in the gum base is enhanced, and the chewing gum becomes too soft to make the chewing comfort worse. When it adheres to a floor material or the like, it spreads thinly even with a slight pressure, and the adhesion tends to become strong. In addition, it <br/> bad the flavor of chewing gum. Conversely, if the number of carbon atoms exceeds 22, the hydrophobicity is increased, the interface between the floor material and the like and the chewing gum is hardly kept in a wet state, the drying becomes easy, and the adhesiveness tends to be increased.

The amount of the PG ester is preferably 1 to 10%, more preferably 3 to 5%, in the gum base of the chewing gum. If the addition amount of the PG ester is less than 1%, the water retention of the chewing gum at the adhesion interface between the floor material and the like and the chewing gum becomes insufficient, and the adhesion preventing effect is hardly obtained. Also, the softening of the gum base is insufficient, and the chewing comfort of the chewing gum tends to be hard. Conversely, if the added amount exceeds 10%, the effect of preventing adhesion is enhanced, but the chewing gum becomes too soft and the chewing feeling is deteriorated. The effect of preventing adhesion tends to be weakened. In addition, a taste peculiar to the PG ester appears, and the flavor of the chewing gum tends to deteriorate.

Further, other emulsifiers, glycerin fatty acid esters, polyglycerin fatty acid esters and the like may be used in combination with the PG ester. It is desirable that the amount added be 5% or less in the gum base. If the addition amount exceeds 5%, the chewing gum becomes too soft and the chewing feeling becomes poor, and when it adheres to a floor material or the like, it tends to spread thinly even with a small pressure, and the adhesion preventing effect tends to be weakened. In addition, the peculiar taste of the emulsifier is obtained, and the flavor of the chewing gum tends to deteriorate.

When a polyglycerin fatty acid ester is used, particularly, the polyglycerin portion is composed of glycerin 8 to
A 10-mer fatty acid having a fatty acid moiety of 12 to 22 carbon atoms is preferred. When the polyglycerin moiety is in the above range, the hydrophilicity is good and the adhesion preventing effect is excellent.

When the fatty acid portion of the polyglycerin fatty acid ester has less than 12 carbon atoms, the hydrophilicity of the gum base is increased, but the chewing gum tends to be softened, the chewing feeling is deteriorated, and the chewing gum tends to deteriorate in flavor. is there. Conversely, when the number of carbon atoms exceeds 22, the hydrophobicity of the gum base is increased, the chewing feeling is hardened, the water retention at the adhesive interface between the chewing gum and the flooring material is weakened, and the adhesion preventing effect is weakened. There is a tendency.

As the gum base of the non-adhesive chewing gum of the present invention, raw materials usually added to the gum base, for example, elastic materials, waxes, inorganic materials and the like are appropriately selected and used. In particular, it is more preferable to increase the mixing ratio of the elastic body and the wax having a high hydrophobicity in terms of the adhesion preventing effect. Examples of the elastic body include natural rubber, polyisobutylene, and vinyl acetate resin, and examples of the wax include, for example,
Rice wax, carnauba wax, microcrystalline wax and the like. These may be used alone or in combination.

The method of adding the PG ester to the gum base is not particularly limited, and it may be mixed with the gum base material and dispersed in the gum base.

The non-adhesive chewing gum of the present invention is prepared by kneading a gum base having the above composition and other raw materials, sugars, softeners, flavors, coloring matters, etc., which are usually added to chewing gum, according to a conventional method. It can be obtained by:

[0021]

As described above, the non-adhesive chewing gum of the present invention contains PG as an anti-adhesion component in a gum base.
Since it contains an ester, it is a chewing gum having an excellent effect of preventing adhesion to not only teeth and dentures, but also floor materials and the like.
In addition, both flavor and texture are comparable to ordinary chewing gum. In addition, its physical properties can be produced using conventional chewing gum production equipment, and can be formed into various shapes. In addition, flavoring, coloring and the like can be freely designed as in the case of conventional chewing gum.

Next, the present invention will be specifically described with reference to examples. <Examples 1 to 8 , Comparative Example 1> (Preparation of gum base) With the composition shown in Table 1, an emulsifier and a gum base substrate excluding inorganic substances were charged into a mixer and heated to 110 to 120 ° C, and the gum base substrate was After melting, they were mixed for 1 hour until homogeneous. Thereafter, an emulsifier and an inorganic substance were added, and after mixing for 15 minutes, the mixture was taken out and cooled to room temperature to obtain a gum base.
