Abstract
An isoflavone aglycone-containing composition having genistein as a main aglycone is produced by a process comprising allowing a protease and &bgr;-glucosidase to act on a soy protein raw material, an extract of a soy protein raw material or a by-product of a soy protein raw material to water-solubilize the protein of soybean origin and to convert isoflavone glycosides to the corresponding aglycones, separating water-soluble components from the enzymatic reaction mixture, and recovering water-insoluble matter.
