Description

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 that does not easily adhere to dentures, floors and the like.

[0002]

2. Description of the Related Art Generally, chewing gum has peculiar viscoelasticity and therefore tends to adhere due to the interfacial force with the tooth surface. This adhesiveness is remarkable especially in the case of dentures such as dentures, and therefore, a person who uses dentures becomes a great obstacle in enjoying chewing gum. In addition, after chewing gum is chewed, chewing gum dust that has not been wrapped in paper and thrown away on the road, floor, etc. tends to adhere and become difficult to dry and peel off over time. More difficult to remove than when attached to dentures. In particular,
Chewing gum is thrown away frequently in public facilities such as in station premises, which spoils aesthetics and is becoming a social problem.

In order to solve such a problem, chewing gum has been improved so far mainly to prevent adhesion to dentures, but although each has some effect on adhesion to dentures, it prevents adhesion to the floor. The effect is insufficient. For example, Japanese Examined Patent Publication No. 58-6455 discloses that a tooth-preventing agent is 0.05 to 3.0% by weight based on chewing gum.
Polyglycerin fatty acid ester (2-7 of 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-tooth agent, it has a tooth-preventing effect and a slight improvement in texture as compared with conventional emulsifiers such as glycerin fatty acid ester and sucrose fatty acid ester. However, roads, floors, and the like are more likely to dry because they are exposed to the atmosphere than teeth in the mouth or dentures, and because their surfaces are rough, they are more likely to adhere than teeth. Therefore, the polyglycerol fatty acid alone is insufficient in the effect of preventing adhesion to floor materials and the like.

A combination of a polyglycerin fatty acid ester and another emulsifier is disclosed in JP-A-60-6693.
10 to 30% by weight of elastic body (hereinafter referred to as "%"), vinyl acetate resin 10 to 35 as disclosed in Japanese Patent Publication No.
%, Hydrocarbon (wax) 20-45%, emulsifier 2-1
Non-adhesive chewing gum with 0% and 8-20% minerals is included. The emulsifier used here is a fatty acid monoglyceride, diglyceride, acetylated monoglyceride, triacetin, polyglycerin fatty acid ester, alone or in a mixture. However, even with this combination, the adhesion to teeth is improved, but the moisturizing property of the chewing gum at the interface between the flooring material and the chewing gum becomes insufficient, and the chewing gum easily dries and the adhesion preventing effect is difficult to obtain. As described above, the conventional non-adhesive chewing gums have the effect of preventing adhesion to the teeth, but the effect of preventing adhesion to floor materials and the like is not recognized, and the reality is that the effect of preventing adhesion is limited. It was

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

[0006]

The above object is achieved by a non-stick chewing gum characterized in that it comprises a propylene glycol fatty acid ester in the gum base.

That is, the inventors of the present invention have studied the emulsifier for chewing gum which can prevent the adhesion to floor materials and the like. As a result, when the propylene glycol fatty acid ester is contained in the gum base, the effect of preventing adhesion to the floor materials and the like is obtained. The inventors have completed the present invention by finding that

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 (hereinafter referred to as "PG ester") used as an anti-adhesion agent is a lipophilic α crystalline emulsifier represented by the following chemical formula 1 or chemical formula 2. is there.

[0009]

[Chemical 1] (In the formula, R represents an aliphatic group.)

[0010]

[Chemical 2] (In the formula, R and R'represent an aliphatic group.)

Among the PG esters, it is preferable to use a monoester or diester of a fatty acid having a fatty acid moiety of 8 to 22 carbon atoms, more preferably a monoester of a fatty acid carbon number of 8 to 12 carbon atoms. It is particularly preferable to use a monoester of fatty acid having 8 carbon atoms,
Examples of such a PG ester include "KB-2" manufactured by Taiyo Kagaku Co., Ltd. and the like. Further, its chemical formula is represented by the following chemical formula 3.

[0012]

[Chemical 3]

When the fatty acid of the PG ester has less than 8 carbon atoms, the hydrophilicity is increased, the action of softening (plasticizing) the elastic body in the gum base is strengthened, and the chewing gum becomes too soft and chewy. When it adheres to a floor material or the like, it spreads thinly even with a slight pressure, and the adhesiveness tends to be stronger. Also, the flavor of chewing gum tends to deteriorate. On the other hand, when the carbon number exceeds 22, the hydrophobicity increases, it is difficult to keep the interface between the flooring and the like and the chewing gum in a wet state, it tends to be dried, and the adhesiveness tends to become strong.

The amount of the PG ester added is preferably 1 to 10%, more preferably 3 to 5% in the gum base of chewing gum. If the amount of PG ester added is less than 1%, the water retention of the chewing gum at the adhesion interface between the flooring material and the chewing gum will be insufficient, and it will be difficult to obtain the effect of preventing adhesion. Further, the softening of the gum base tends to be insufficient, and the chewing gum tends to be hard to chew. On the other hand, if the amount added exceeds 10%, the adhesion preventing effect is enhanced, but the chewing gum becomes too soft and the chewing gum becomes uncomfortable, and when it adheres to a flooring material, etc., it becomes thin and easily spreads, The anti-adhesion effect tends to weaken. In addition, the taste peculiar to PG ester is produced, and the flavor of chewing gum tends to be deteriorated.

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

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

When the number of carbon atoms in the fatty acid portion of the polyglycerin fatty acid ester is less than 12, the hydrophilicity of the gum base increases, but the chewing gum tends to soften and the chewing gum becomes uncomfortable and the chewing gum tends to have a poor flavor. is there. On the other hand, when the carbon number exceeds 22, the gum base becomes more hydrophobic, and the chewing feeling becomes harder, and the water retention property at the adhesion interface between the chewing gum and the floor material becomes weaker, and the adhesion preventing effect becomes weaker. There is a tendency.

For the gum base of the non-adhesive chewing gum of the present invention, the raw materials usually added to the gum base, for example, elastic body, wax, inorganic substance, etc. are appropriately selected and used. In particular, increasing the blending ratio of the highly hydrophobic elastic body and the wax is more preferable in terms of the effect of preventing adhesion. Examples of the elastic body include natural rubber, polyisobutylene, and vinyl acetate resin, and examples of the wax include:
Rice wax, carnauba wax, microcrystalline wax, etc. are mentioned. 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 raw material and dispersed in the gum base.

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