Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to the improvement of gum bases and cams, and more particularly, to the improvement of gum bases and cams, and more particularly, the use of unique fillers in gum bases to provide gums with good texture and physical properties. Regarding improvements that give.

[Prior Art] At present, the main fillers used in gum bases are calcium carbonate and talc, each of which is made by finely pulverizing and refining natural minerals to a particle size of several microns. It is an inorganic substance.

These fillers are used for rolling, cutting, and
This is to adjust the workability of packaging, etc., and the sensory properties such as chewability and swelling of bubble gum. Although it is possible to uniformly mix this type of filler into the gum base, it does not necessarily have good affinity with the gum base base material composed of organic substances, and there is a limit to the ability to obtain a smooth chewing sensation. In addition, this type of filler is completely hydrophobic, so when chewing gum during the day, there is less saliva infiltration into the gum base, and it may harden to the touch over time, and in the case of balloon cams. , the swelling membrane tends to become thinner and more difficult to swell.

When trying to improve sensory properties by considering fillers,
Within the range of existing inorganic substances, there is no significant difference in functionality and no significant improvement effect can be expected.

Examples of new materials used in gum-based fillers include cellulose microcrystalline powder described in Japanese Patent Publication No. 41-135, natural fiber powder such as sugar beet pulp described in Japanese Patent Publication No. 4537827, It has a good affinity with gum base base materials, which are mainly composed of the same organic substances as resins and rubbers, and has the effect of providing a smooth texture with a uniform structure, but many of these types of fillers are hydrophilic. It has a strong tendency to absorb saliva and swell in the mouth, making it soft to the touch.

As a result of continuing research to provide a new material for use in gum-based fillers that uses natural organic substances to overcome these drawbacks of conventional fillers, we have recently developed a new material extracted and purified from natural plants. Find out that the substance is extremely effective for this purpose.

[Problems to be Solved by the Invention] An object of the present invention is to provide a gum base and a cam that provide a gum with good texture and physical properties 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 lignin as a filler.

Lignin is one of the main components of solidified plants such as wood, bamboo, and straw. Although lignin can be separated from plants, acid-hydrolyzed lignin separated by acid hydrolysis using sulfuric acid or hydrochloric acid is effective in the present invention.

Acid-hydrolyzed lignin is the residue of acid saccharification of plants, so
Two typical acid saccharification methods: 5c using sulfuric acid
In both the Holler method and the Rheinau method using hydrochloric acid, the sugar solution is separated from the sugar solution by centrifugation or filtration, and if necessary, after washing, it can be used as a filler for a gum base.

Acid-hydrolyzed lignin is a residue from acid saccharification of plants, and after hydrolysis, water-soluble components have been removed.
Compared to lignin, which cannot be extracted by sulfide cooking or Kraft cooking, it has weaker hydrophilicity and less chemical reactivity.
When acid-hydrolyzed lignin is used as a gum base filler, it is moderately compatible with saliva and has little effect on flavor.

The blending ratio of lignin is 2.5 to 4 based on the gum base.
A range of 0% by weight is suitable.

More preferably, the lignin content is in the range of 8 to 15% by weight based on the gum base.

It is preferable that the lignin extract used in the present invention contains 90% by weight or more of lignin, and the coexisting substances other than lignin are cellulose or hemicellulose.

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

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

According to the present invention, there is further provided a chewing cam or bubble gum characterized in that it uses the above-described gum base containing acid-hydrolyzed lignin as a filler.

[Function] When considering natural fibers, gum arabic, pectin, guar gum, etc., which are called gums, belong to water-soluble polysaccharides, and even if they are added to a gum base, they dissolve during chewing and are not used as fillers. does not fulfill its function. In addition, cellulose, hemicellulose, chitin, etc. are insoluble polysaccharides, so they do not elute, but because they are highly hydrophilic, they absorb a considerable amount of saliva during chewing and swell, softening the gum base itself and increasing its elasticity. In extreme cases, it can lead to deterioration. On the other hand, lignin-based polymers are polymers with a very special structure different from polysaccharides, and their wood-philic properties are not as strong, and their water swelling properties are moderately suppressed, giving them a smooth and consistent feel. It has the effect of maintaining

When examining various types of lignin, as mentioned above, lignin has an extremely complex structure and is bonded to cellulose and hemicellulose in plants, making it difficult to isolate it in its original form. Currently, the mainstream method for industrially extracting lignin is sulfide cooking, which introduces a sulfonic group into the 2nd position of the side chain of the phenylpropane structure, and extracts it as gutsulfonic acid. lignin) and mineral acid treatment (acid hydrolyzed lignin). Lignosulfonic acid and kraft lignin have high chemical reactivity due to their structure, and when used in a gum base, they have a strong tendency to react with constituent components including flavorings, particularly having a negative effect on flavor. In addition, it has relatively strong hydrophilic properties and has a large swelling property, which tends to reduce the elasticity of the gum base more than necessary. On the other hand, acid-hydrolyzed lignin can be used to treat wood with sulfuric acid (Heller method) or hydrochloric acid (Rhe
Inau method), it is hydrolyzed and water-soluble components are removed, and it has weaker hydrophilicity and poor chemical reactivity compared to lignosulfonic acid and kraft lignin. Therefore, when used as a gum-based filler, it blends appropriately into saliva and does not affect flavor or the like.

The blending ratio of acid-hydrolyzed lignin is preferably in the range of 2.5 to 40% by weight based on the gum base. This addition rate is critical; if the amount of lignin is less than this, the effect of improving masticatory properties as a filler will not be recognized, and if the amount is too large, the physical properties of the gum base base agent will be suppressed too much, resulting in poor elasticity. It's reduced, giving it a flat feel.

[Effects of the Invention] According to the present invention, a gum base and a gum are provided that provide good texture and physical properties to the gum obtained by using a unique filler in the gum base. Acid-hydrolyzed lignin, which is extracted and purified from plants, has moderate hydrophilicity and is compatible with saliva, but it does not absorb water and swell more than necessary, so it maintains a very smooth and constant elasticity for a long time. Gives a lasting effect. In addition, for the same reason, bubble gum has the advantageous effect of imparting flexibility to the swollen film, making it easy to swell and swell to a large extent.

After decomposition and treatment, the sugar solution is separated by centrifugation or filtration, and the low molecular weight fraction is removed, followed by washing and drying to adjust the average particle size to 10 to 20 μm.
