Equol-containing extract and its production method, equol extraction method, and food containing equol

摘要

PROBLEM TO BE SOLVED: To provide an extract obtained by extracting a useful component containing equol from a fermented soybean hypocotyl containing equol, and a method for producing the same. In the present invention, an equol-containing soybean hypocotyl fermented product is subjected to an extraction treatment using an ethanol aqueous solution as an extraction solvent, whereby useful components containing equol are efficiently extracted from the soybean hypocotyl fermented product. do. Furthermore, by sequentially performing an extraction treatment using an aqueous ethanol solution and an extraction treatment using ethanol on the fermented soybean hypocotyl containing equol, equol and glycitein can be efficiently extracted and cause unpleasant taste. The content of saponin can be reduced. [Selection diagram] None
