JPH089889A - Nonsticky chewing gum - Google Patents

Abstract

PURPOSE:To obtain a nonsticky chewing gum, containing collagen in a gum base and excellent in preventing effects on sticking to not only tooth or denture but also flooring, etc. CONSTITUTION:This gum contains preferably 2-18wt.%, more preferably 15-18 wt.% collagen in a chewing gum base. Besides the collagen, e.g. an elastic body, a wax or an inorganic substance may be used. When the blending ratio of the elastic body having a high molecular weight and a wax having a high melting point is especially raised, the resultant chewing gum is more preferred from the viewpoint of preventing effects on the sticking. The nonsticky effects are further preferred if a propylene glycol ester of a fatty acid represented by the formula (R is an aliphatic group) is blended.

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. Also, after chewing gum is chewed, chewing gum dust that has not been wrapped in paper and thrown away on the road, floor, etc. easily adheres and becomes difficult to dry and peel off over time. It is more difficult to remove than in the case of adhesion to etc. 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 conventionally improved mainly to prevent adhesion to dentures, but all have some effect on adhesion to dentures, but prevent adhesion to the floor. Is insufficient. For example,
JP-B-58-6455 discloses that 0.05 to 3.0% by weight of polyglycerin fatty acid ester (2 to 7 mer of glycerin;
It is disclosed that a fatty acid having 12 to 20 carbon atoms) is added. When polyglycerin fatty acid ester is used as an anti-tooth agent, the tooth-preventing effect is recognized as compared with conventional emulsifiers such as glycerin fatty acid ester and sucrose ester, and some improvement in texture is recognized. However, roads, floors, etc. are more likely to dry because they are exposed to the atmosphere than teeth in the mouth or dentures, and their surfaces are rough, so that they are more likely to adhere than teeth. Therefore, the polyglycerin fatty acid ester alone is insufficient in the effect of preventing adhesion to floor materials and the like.

As a combination of polyglycerin fatty acid ester and other emulsifiers, 10 to 30% by weight of an elastic body (hereinafter referred to as "%") and 10 to 35 of vinyl acetate resin are used.
%, Hydrocarbon (wax) 20-45%, emulsifier 2-1
A non-adhesive chewing gum having 0% and 8 to 20% inorganic substance can be mentioned (JP-A-60-66938). The emulsifier used here is a fatty acid monoglyceride, diglyceride, acetylated monoglyceride, triacetin, polyglycerin fatty acid ester, alone or in a mixture. However, even if these combinations are used, the adhesion to teeth is improved, but the chewing gum has insufficient moisture retention at the interface between the floor material and the chewing gum, making it easier to dry and preventing adhesion to the floor material. The 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

[0005]

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 containing collagen in a gum base.

That is, the inventors of the present invention have particularly studied the components that prevent adhesion to flooring materials, etc., and as a result, when collagen is added to the chewing gum base, when the chewing gum is chewed in the mouth, water derived from saliva is removed. Since it is retained by collagen, the chewing gum surface (the interface between the chewing gum and the floor material, etc.) remains wet for a long time even after the chewing gum is chewed away, which prevents the chewing gum from sticking to the floor material, etc. The present invention has been completed by finding that the effect is remarkably improved.

Next, the present invention will be described in detail. Collagen used as an anti-adhesive component in the gum base of the non-adhesive chewing gum of the present invention, among the simple proteins,
It is one of the hard proteins existing in animal tissues such as skin, tendon, bone, ligament, etc. It is also an aggregate of fibers called collagen, and the thin fibers have a regular striated structure. . Although its molecular weight and structure have not been sufficiently clarified, it is presumed that multiple peptide chains form a three-dimensional structure.As the amino acid composition, there are almost no sulfur-containing amino acids or tyrosine, and glycine, It is known that proline, oxyproline and the like are abundant. In addition, the production method differs depending on the raw material and application, but the mixed substances are removed from animal tissues by extraction with organic solvents, washing with water, extraction with dilute hydrochloric acid solution, acid and alkali treatment, enzyme action of trypsin and hyaluronidase, etc. However, it is common to leave collagen as a water-insoluble substance. Specific examples of the water-insoluble collagen include "collagen powder 1000" and "collagen powder 1000".
L ”,“ collagen powder DF ”(both manufactured by Sardine Research Institute) and the like. Also, when the animal tissue is defatted and extracted with a citrate buffer or the like and dialyzed, it becomes soluble collagen. A specific example of this soluble collagen is "edible collagen E-CAN" (Nippon Shoji Co., Ltd.).
Manufactured) and the like. These may be used alone or in combination of two or more. In addition, the above-mentioned collagen is more preferable in terms of the water retention effect when blended in a chewing gum base in a powder state. When the above collagen is solubilized and used,
When chewing gum is chewed in the mouth, the effect of retaining water derived from saliva tends to be weakened. The particle size of the collagen powder is preferably 80 mesh pass, and more preferably smaller than 120 mesh pass because it is less likely to affect the texture of chewing gum.

The above collagen content is preferably 2 to 18% by weight (hereinafter referred to as "%"), more preferably 15 to 18%, based on the total weight of the chewing gum base. If the collagen content is less than 2%, the effect of retaining water in the chewing gum tends to be weakened, while if it exceeds 18%, the collagen tends to detach from the chewing gum during chewing and the moisture retaining effect is not sufficiently exerted. Also, chewing gum tends to have a powdery texture.

The induced protein obtained by boiling collagen with water, dilute acid, dilute alkali, etc. for a long time to heat-denature it to change the peptide bond in collagen is gelatin, which is different from the collagen of the present invention. It is a thing.
Therefore, even if gelatin is used, the effect of preventing adhesion, which is the object of the invention, cannot be obtained.

In the gum base of the non-adhesive chewing gum of the present invention, in addition to the above collagen, raw materials usually added to the gum base, such as an elastic body, a wax and an inorganic substance, are appropriately selected and used. In particular, increasing the blending ratio of the elastic body having a high molecular weight and the wax having a high melting point is more suitable in terms of the anti-adhesion effect. Examples of the elastic body include natural rubber, polyisobutylene, and vinyl acetate resin, and examples of the wax include rice wax, carnauba wax, and microcrystalline wax. These may be used alone or in combination.

Further, in addition to the above-mentioned raw materials, it is more preferable to add an emulsifier such as propylene glycol fatty acid ester (hereinafter referred to as "PG ester") or polyglycerin fatty acid ester in view of improving non-adhesion effect. That is, in order to improve the texture while maintaining non-adhesiveness,
Even when the amount of collagen added is reduced, the use of PG ester in combination can achieve the same degree of anti-adhesion effect as when an optimal amount of collagen is added. The PG ester is an emulsifier represented by the following chemical formula 1 or chemical formula 2.

[0013]

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

[0014]

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

Among the above PG esters, it is particularly 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 having a fatty acid carbon number of 8, and examples of such a PG ester include "KB-2" manufactured by Taiyo Kagaku Co., Ltd. The chemical formula is shown below.

[0016]

[Chemical 3]

When the fatty acid of the above-mentioned PG ester has less than 8 carbon atoms, the hydrophilicity of the gum base increases and 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 becomes thin and spreads thinly even if it is slightly pressed, and the adhesiveness tends to be strong. Also,
Chewing gum tends to have a bad flavor. On the other hand, if the carbon number exceeds 22, the gum base becomes more hydrophobic, so it is difficult to keep the adhesion interface between the floor material and the chewing gum in a wet state, and it becomes easier to dry and the adhesion to the floor material is improved. Tend to be stronger.

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 chewing gum will have insufficient water retention at the adhesion interface between the flooring material and the chewing gum, and the effect of preventing adhesion will be difficult to obtain, and the softening of the gum base will be insufficient, resulting in chewing gum. The texture tends to be hard. On the contrary, if the addition amount exceeds 10%, the chewing gum becomes too soft, though the anti-adhesion effect is enhanced.
When it becomes uncomfortable to chew and adheres to floor materials,
Even a slight pressure spreads thinly, and the anti-adhesion effect tends to weaken. Moreover, the taste peculiar to PG ester tends to deteriorate the flavor of chewing gum.

Further, other emulsifiers such as glycerin fatty acid ester and polyglycerin fatty acid ester may be used together with the PG ester. It is desirable that the added amount be 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 floor material or the like, it spreads thinly with a slight press, and the effect of preventing adhesion tends to weaken. Further, the taste peculiar to the emulsifier tends to deteriorate the flavor of the chewing gum.

Among the polyglycerin fatty acid esters, when the polyglycerin portion is a glycerin 8- to 10-mer and the fatty acid portion is a fatty acid having 12 to 22 carbon atoms, the hydrophilicity of the gum base is moderate. And the anti-adhesion effect is further improved. When the carbon number of the fatty acid portion of the polyglycerin fatty acid ester is less than 12,
The chewing gum tends to soften due to excessively high hydrophilicity of the gum base, which makes chewing gum uncomfortable and tends to deteriorate the flavor of the chewing gum. On the contrary, the carbon number is 2
When it exceeds 2, the gum base becomes hydrophobic and the chewing feeling becomes hard, and the water retention of the chewing gum at the adhesion interface between the chewing gum and the flooring material tends to be weakened, and the adhesion preventing effect tends to be weakened.

The non-adhesive chewing gum of the present invention is prepared according to a conventional method by kneading together the above-mentioned raw materials and other raw materials (sugars, softeners, flavors, pigments, etc.) usually added to chewing gum. It is obtained by doing.

[0022]

As described above, since the non-adhesive chewing gum of the present invention uses collagen as an anti-adhesion component, it is a chewing gum excellent in non-adhesion to not only teeth and dentures but also floor materials and the like. Yes, and its flavor and texture
Both are comparable to normal chewing gum. In addition, the production thereof does not require a particularly complicated process or equipment, can be produced using conventional chewing gum production equipment, and can be formed into various shapes. Further, flavoring, coloring and the like can be freely designed as in the conventional chewing gum.
