Abstract

See full text

The present invention relates to an extract obtained by extracting useful components containing equal 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 equal-containing fermented soybean hypocotyl to extraction using an ethanol aqueous solution and ethanol, while efficiently extracting equol and glycitein.
