JP5208723B2 - Deodorant composition - Google Patents

Description

  The present invention relates to a deodorant composition comprising an extraction residue after extraction of a mint flavor component and an oxidoreductase, and a chewing gum comprising the deodorant composition.

  Conventionally, various deodorizing ingredients have been used to remove unpleasant odors such as bad breath. Among them, those using plant extracts and oxidoreductases as deodorizing components are known to have a large deodorizing effect (Japanese Patent Laid-Open Nos. 63-309269, 9-38183, and 10). No. -212221 and JP-A No. 2004-321077). However, when these deodorizing ingredients are applied to chewing gum, for example, a small amount cannot exert a sufficient effect, so it is necessary to add a large amount. However, adding a large amount affects the taste and is disadvantageous in terms of cost. . In addition, these deodorizing components also have a problem that the deodorizing effect is inferior under acidic conditions (for example, a state where saliva pH becomes 5 or less by chewing a sour food).

Summary of the Invention

  Surprisingly, the present inventors have found that when the distillation residue obtained after steam distillation of peppermint or spearmint and the redox enzyme are added to the chewing gum, the amount of peppermint or spearmint distillation residue is small. It was also found that chewing gum having a very high deodorizing effect can be obtained even under acidic conditions (Test Examples 1 and 2). The present invention is based on this finding.

  An object of the present invention is to provide a deodorant composition that exhibits a high deodorizing effect even in a small amount or under acidic conditions when applied to food (especially chewing gum). .

  According to the present invention, there is provided a deodorant composition (hereinafter referred to as “deodorant composition according to the present invention”) comprising an extraction residue after extraction of a fragrance component of mint and an oxidoreductase.

  According to the present invention, there is also provided a chewing gum comprising the deodorant composition according to the present invention (hereinafter referred to as “chewing gum according to the present invention”).

  The deodorant composition according to the present invention is advantageous in terms of taste and cost compared to conventional deodorant components because a high deodorant effect can be obtained even if the amount of the extraction residue after extraction of the mint perfume component is small. Moreover, since the deodorizing effect can be sufficiently exerted even under acidic conditions, it is advantageous in that it can be used for foods having a sour taste such as fruit taste. The deodorant composition according to the present invention is advantageous in that it is preferable for application to chewing gum because a high deodorizing effect can be obtained even in a small amount or under acidic conditions as compared with conventional deodorant components. is there.

  In addition, the deodorant composition according to the present invention and the chewing gum according to the present invention are advantageous in that the cost can be reduced by effectively utilizing the extraction residue after the extraction of the fragrance component of mint.

Detailed Description of the Invention

Deodorant Composition The deodorant composition according to the present invention is a composition comprising an extraction residue after extraction of the fragrance component of mint and an oxidoreductase.

  In the present specification, “extraction residue after extraction of flavor components of mint” means the remaining mint extracted from the flavor components of mint. The “extraction residue after extracting the fragrance component of mint” can be prepared from the remaining mint after the mint is subjected to the fragrance component extraction step and the fragrance component is extracted. The remaining mint after extracting the fragrance component may be used as it is, or may be used after drying. The dried mint may be further pulverized for use.

  Mint means a perennial plant belonging to the family Labiatae, preferably peppermint or spearmint.

  Mint can be used in the extraction of perfume ingredients in the raw state, or the dried product, all or a portion such as a leaf or stem.

  Examples of the method for extracting the fragrance component include known methods such as distillation and solvent extraction. Examples of the distillation include steam distillation and vacuum distillation. Examples of the solvent extraction include extraction with a polar solvent (water, ethanol, etc.) and a nonpolar solvent (fatty acid glyceride, hexane, acetone, etc.), preferably extraction with a nonpolar solvent.

  In the present invention, the “oxidoreductase” is not particularly limited as long as it meets the object of the present invention, but is preferably polyphenol oxidase, and more preferably laccase.

  A commercially available oxidoreductase may be used, or a oxidoreductase produced according to a known method may be used.

  When it is desired to maintain the deodorizing effect for a long period of time, the oxidoreductase can be used by being encapsulated in a capsule formed of a coating such as gelatin.
