Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to improvement of gum bases and gums, and more particularly, to improvement of gum bases and gums, and more particularly, to improve chewing texture and physical properties of gums obtained by using unique fillers in gum bases. Regarding improvements that give.

[Prior art] Gum base is an insoluble material composed of hydrophobic substances such as rubber, resin, hydrocarbons, oils and fats, and inorganic substances. In some countries, tribasic calcium phosphate, etc. are used for gum base. Generally, inorganic substances such as calcium carbonate or talc are used as fillers. Calcium carbonate and talc are inorganic substances obtained by beneficiation and washing of natural minerals such as limestone or talc, respectively, and then mechanically pulverized to fine particles of several microns, and are mixed into the gum base base agent by hot melt mixing. The purpose of using these fillers is to adjust the workability of rolling, cutting, packaging, etc. during cam manufacturing, as well as sensory properties such as chewability and swelling of bubble gum. Calcium carbonate and talc have good miscibility with natural resins, vinyl acetate resin, synthetic rubber, etc. used as base agents for gum bases, and are effective in adjusting physical properties such as softening elasticity, but they are insoluble inorganic substances and are not compatible with saliva. As a result, the cam lacked smoothness, and the feel tended to harden if chewed for a long time.

New materials used in gum-based fillers include natural fibers such as cellulose microcrystalline powder described in Japanese Patent Publication No. 41-135 or sugar beet pulp described in Japanese Patent Publication No. 45-37827. The powder has a good affinity with gum base base materials, which are mainly composed of the same organic substances as resins and rubbers, so it has the effect of providing a smooth texture with uniform fibers, but this type of filler Most of them are highly hydrophilic and absorb saliva in the mouth and swell, which tends to soften the texture.

In order to eliminate these drawbacks of conventional fillers, we searched for materials that have appropriate hydrophilicity and are compatible with saliva, and as a result, we have found that a certain type of material derived from natural plants is suitable for this purpose. I figured it out.

``Problems to be Solved by the Invention'' The objective of the present invention is to provide a gum base and a cam that provide good texture and physical properties to the cam obtained by using a unique filler in the gum base.

[Means for Solving the Problems] According to the present invention, there is provided a gum base characterized by containing, as a filler, a fine powder of rice husk obtained by finely pulverizing rice husk.

Because rice husk is hard, it was considered difficult to use it for food. Rice husks consist of cellulose, hemicellulose, likunin, and inorganic substances, and the mixture of these components gives the gum base good texture and physical properties.

It is preferable that the blending ratio of the fine rice husk powder obtained by finely pulverizing the rice husk is in the range of 2.5 to 40% by weight based on the gum base.

It is preferable that the rice husk fine powder obtained by finely pulverizing the rice husk is compressed and crushed.

The rice husk fine powder obtained by finely pulverizing the rice husk is subjected to a pressure of 108/c.
It is preferable to prepare the compressed product by compressing and crushing it at a temperature of 200° C. or more and performing purification treatments such as decolorization and deodorization after crushing the resulting compressed product.

Rice husk fine powder obtained by finely pulverizing rice husk is heated to a pressure of 108/C.
It is preferable to prepare the compressed product by compressing and crushing it at a temperature of 200° C. or higher and performing purification treatments such as decolorization and deodorization of the resulting compressed product, followed by pulverization.

Preferably, it is prepared by compressing and crushing a fine powder of rice hus obtained by pulverizing rice husks, and removing a portion of cellulose and/or hemicellulose from the resulting compressed and crushed rice husks to form a fine powder. It is.

By removing a portion of cellulose and hemicellulose and pulverizing them, the degree of hydrophilicity is lowered and the swelling property due to saliva absorption is reduced, which can be used in relatively large quantities because the negative effects of these are relatively reduced. and preferably 5~
It can be used within a range of 20%.

Rice husk fine powder obtained by finely pulverizing rice husk has an average particle size of 100
A suitable gum base can be obtained if it has a particle size of less than .mu. and contains 5.5 to 8.5% water.

Suitable gum bases may be obtained by further including as fillers insoluble natural mineral substances selected from the group consisting of talc, acid clay, kaolin, penite, diatomaceous earth, perlite, and the like.

Suitable gum bases can be obtained by further including calcium carbonate and/or tribasic calcium phosphate as fillers.

The rice husk fine powder obtained by finely pulverizing the rice husk of the present invention includes talc, acid clay, kaolin, bentonite, diatomaceous earth,
It can optionally be used in combination with an insoluble natural mineral substance selected from the group consisting of pearlite and similar substances, or an inorganic filler such as calcium carbonate or tribasic calcium phosphate. 5～
A range of 40% is preferred.

According to the present invention, there is further provided a chewing cam or a balloon cam characterized by using the above-described gum base containing as a filler a fine powder of rice hus obtained by finely pulverizing rice husk.

[Function] The present invention discloses for the first time the application of rice husk fine powder obtained by finely pulverizing rice husk to gum.

For example, on September 10, 1988, Kagaku Nippo reported on the application of fine powdered rice husks to a phenolic resin compound for lacquerware, and in Special Publication No. 11949/1983, there was a report on the application of fine powdered rice husks to a phenolic resin compound for lacquerware. , describes a method for modifying synthetic polymer compounds by adding powders such as branches and leaves, and is published in Japanese Patent Publication No. 57-319.
Publication No. 43 describes a method for producing a powder of the husk, trunk, branches, leaves, etc. of the seeds of a plant belonging to the Carotidaceae family, which contains silicic acid and is intended to be used as an extender for feed, fertilizer, and building materials. This paper does not teach the application of the fine rice husk powder obtained by the process to gum.

When considering the components of rice husk, the main components of the rice husk of the present invention are 30-33% cellulose, 15-18% hemicellulose, 20-22% lignin, and 9-9% silica.
20%, moisture content 7-9%. This value varies within a certain range depending on the type of rice husk, analysis method, etc. Among these, hemicellulose, which is mainly composed of cellulose and xylan, is a highly hydrophilic organic polymer that absorbs water and has a tendency to swell, while lignin is a hydrophobic organic polymer that is not compatible with water, and silica is a completely hydrophobic inorganic substance. If only cellulose and hemicellulose are used as fillers in the gum base, the gum absorbs excessive amounts of saliva and becomes too soft; however, the mixture of lignin and inorganic substances in the rice husk fine powder alleviates the softening and creates a suitable gum base or cam. There is a tendency for better results to be obtained as the proportion of 6-silica, which is estimated to be present, is higher. The extremely characteristic composition of fine rice husk powder is that organic and inorganic substances with different properties are mixed in a certain ratio, and when used as a filler in a gum base, it has a moderate affinity for saliva. It provides a constant chewing sensation without hardening, and also results in the formation of a thick and stable film on the balloon cam.

When we consider the crushing of rice husks, we find that rice husks have an extremely tough structure in which various polymers form needle-shaped crystals and are bonded to silica, and this part is subject to severe wear and tear in ordinary crushers, making it uneconomical. It is difficult to pulverize into fine particles. However, the environmental temperature is 200°C or higher, the pressure is 108/C111
When crushed with 2 or more, partial decomposition of polymers such as lignin and hemicellulose occurs, and the original tissue dissociates, resulting in 1
This facilitates pulverization into particles of 00 μm or less.

For refining, the carefully crushed rice husks are continuously crushed and then subjected to treatments such as alkaline washing and acid washing to remove water-soluble colored substances, malodorous substances, and highly reactive low-molecular substances, and then dried. Alternatively, the crushed crystals themselves may be subjected to similar treatment and then crushed. When used as a filler, the fine rice husk powder obtained by finely pulverizing the rice husk of the present invention has considerably flexible physical properties, and unlike inorganic materials,
There is no need to extremely finely powder the average particle size of 10
A good value is 0μ or less, preferably about 20μ.

The rice husk fine powder obtained by finely pulverizing the rice husk of the present invention has a stronger physical property adjustment effect as a filler than an inorganic substance, and has a 2.5%
It is effective to some degree. If excessively added to the gum base,
Swelling properties due to saliva absorption are strengthened, softening the feel of the cam, and furthermore, the filler cannot be retained in the gum base, dissolves during the day, and does not adversely affect taste. Therefore, a critical effect can be obtained within a predetermined addition rate range. The upper limit that can be blended is 40%, and the preferred range is 5%.
~15%, but as mentioned above, if a part of cellulose or hemicellulose is removed and pulverized to reduce hydrophilicity and swelling due to saliva absorption, there will be no adverse effects due to these. It is relatively reduced and can be used in relatively large quantities.

[Effects of the Invention] According to the present invention, a gum base and a cam are provided which provide good texture and physical properties to the cam obtained by using a unique filler in the gum base. Although rice husk is a natural product, it has a special composition consisting of inorganic substances, hydrophilic organic polymers, and hydrophobic organic polymers, and has both an affinity for gum base base agents and an affinity for saliva. Because it is a filler, cams that use it as a filler have a smooth, consistent feel and do not harden even with continued chewing. In addition, in the balloon cam, flexibility is added to the swollen membrane (=J
The favorable result is that the balloon is easy to inflate and has a large, thick membrane.

The rice husks are heat-compressed and crushed using a compressor at 50t/cm2 under conditions of 300°C, and the average particle size is 20μ using an atomizer.
It was pulverized to a fine powder. The obtained fine powder was washed with an alkali, neutralized, washed with water, and dried to obtain a purified rice husk fine powder. By weight it contained 18% lignin, 31% cellulose, 15% hemicellulose, and 18% silica.
