Description

  The present invention relates to a polyphenol composition containing a cyclodextrin and a collagen peptide, and a food and drink and an oral hygiene product characterized by containing the composition.

  Recent studies have revealed that plant-derived polyphenols have various physiological effects such as blood lipid and LDL antioxidant activity, antibacterial properties, renal failure improving effect, deodorizing effect, and food flavor deterioration preventing effect. However, since polyphenol has a peculiar bitterness, astringency and astringency, it has a drawback that it is difficult to process into food and drink. As a technique for improving this, a method in which dextrin is allowed to act on polyphenol with an enzyme (for example, see Patent Document 1), a method using egg white or a plant protein (for example, see Patent Document 2), or a method using casein. (For example, refer to Patent Document 3), a method of including polyphenol in β-cyclodextrin (for example, refer to Patent Documents 4 and 5), a method using β-cyclodextrin and casein (for example, refer to Patent Document 6) ), Methods using cyclodextrins and peptides (for example, see Patent Document 7), etc. are known, but these techniques are not sufficient in improving the bitterness, astringency and astringency, and the protein taste is not good. Further, there is a problem that it is not dissolved and dispersed in water, and further improvement is desired.

  In particular, Patent Document 7 describes a method using a cyclodextrin and a peptide. However, since sardine peptide is used as a peptide in this technique, fish odor derived from sardine peptide is more intense than bitterness. There was a problem that was unsuitable for eating and drinking. Despite the fish odor problem peculiar to sardine peptides, the types of other peptides, their molecular weights and tastes have not been studied at all. Furthermore, although the effect of reducing bitterness has been studied for a composition comprising cyclodextrin and peptide, the relationship between astringency and astringency has not been studied at all.

  Patent Document 8 reports a technology that does not generate these insolubles by adding pectin, because when a polyphenol is added to a food containing water-soluble protein such as collagen, gelatin, or collagen peptide, a cloudy substance or a precipitated substance is generated. Has been. This suppresses the generation of white turbid substances and precipitated substances generated by polyphenols and proteins by the addition of pectin, but there is still a problem that turbidity is generated when stored for a long period of time or at low temperatures. Furthermore, in the present invention, no consideration has been given to how the taste of polyphenols is affected by water-soluble proteins.

JP-A-8-298930 JP-A-2-202900 JP 2005-124540 A Japanese Patent Laid-Open No. 4-255792 JP 2004-159505 A JP-A-2005-73534 JP-A-3-16846 JP 2002-27957 A

  Thus, the techniques invented so far are not sufficient to improve the bitterness, astringency and astringency of peculiar to polyphenols, and when mixed with food and drink and oral hygiene products, the bitterness, astringency and astringency are produced. End up. Further, there are problems such as fish odor such as sardine peptide and insoluble matter produced by the reaction of water-soluble protein such as casein and collagen with polyphenol, and so on. It is a well-known fact that polyphenols have a wide variety of physiological functions, and efficient intake is desired, but the amount of use is limited due to taste problems and water insolubility problems.

  It is an object of the present invention to provide a polyphenol composition that retains the original physiological functions of polyphenols and has improved the unique bitterness, astringency and astringency, and food and beverage products and oral hygiene products containing the composition. To do.

  As a result of intensive studies aimed at solving the above-mentioned problems, the present inventors have found that the mixture of cyclodextrin and collagen peptide reduces the bitterness, astringency and astringency unique to polyphenols, and further the flavor specific to peptides. Thus, the present inventors have found that a composition having the original functionality of polyphenols can be obtained without producing an insoluble substance even in an aqueous solution.

  According to the present invention, it has been found that the bitterness, astringency and astringency unique to polyphenols are sufficiently suppressed by preparing a polyphenol composition composed of polyphenol, cyclodextrin and collagen peptide. Furthermore, it has been found that there is no bitterness and flavor peculiar to peptides, and insoluble substances are not generated even in aqueous solutions, and it can be used for beverages and oral hygiene products. In particular, in a packaged tea beverage of polyphenols contained in a high concentration, the bitterness, astringency and astringent taste were reduced. In addition, it was found that pigmentation on the teeth during drinking was suppressed, and transparency was maintained even during long-term storage and a good flavor was obtained, so that it was suitable for regular drinking. As a result, the range of application to food and drink is widened, and the industrial contribution is large.
