  • EQUOL-CONTAINING EXTRACT, METHOD FOR PRODUCTION THEREOF, METHOD FOR EXTRACTION OF EQUOL, AND EQUOL-CONTAINING FOOD
    Publication number: 20200253251
    Abstract: The present invention relates to an extract obtained by extracting useful components containing equol from an equol-containing fermented soybean hypocotyl, and to a method for producing the same. The present invention makes it possible to efficiently obtain useful components containing equol from the fermented soybean hypocotyl by subjecting an equol-containing fermented soybean hypocotyl to extraction using an ethanol aqueous solution as an extractant. The present invention reduces the content of saponin, which causes an unpleasant taste, by sequentially subjecting the equol-containing fermented soybean hypocotyl to extraction using an ethanol aqueous solution and ethanol, while efficiently extracting equol and glycitein.
