Title:
POLYPHENOL STABILIZER, AND COMPOSITION AND PROCESSED GOODS CONTAINING SAID STABILIZER
Document Type and Number:
WIPO Patent Application WO/2013/141267
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a polyphenol stabilizer which, in processed goods which contain polyphenols such as cacao procyanidins or tea catechins, can minimize the epimerization of epicatechins or the decrease of procyanidins, the epimerization and the decrease occurring either during thermal extraction or heat sterilization or in storage under neutral or alkaline conditions; and a composition, food, drink, drug or cosmetic that contains the stabilizer. The stabilization of a polyphenol can be attained by making a stabilizer containing ellagic acid and/or punicalagin coexist with the polyphenol. The stabilizer may be a plant extract such as pomegranate extract, purified ellagic acid, purified punicalagin or a mixture of two or more of them.
