Abstract:
1. A water-soluble isoflavone composition, consisting essentially of an α-glucosyl isoflavone, isoflavone and isoflavone aglycone and having a total amount of an isoflavone in α-glucosyl isoflavone excluding a saccharide(s) added to the isoflavone, isoflavone and isoflavone aglycone in said water-soluble isoflavone composition being 20 to 90% based on a dry solid basis, wherein said α-glucosyl isoflavone is composed of isoflavone to which an average number of 2.0 to 20 glucoses linked in series via the α-linkage, the ratio of the amount of aglycone in said α-glucosyl isoflavone to the amount of aglycone in said isoflavone and said isoflavone aglycone in total [(the amount of aglycone in α-glucosyl isoflavone)/(the amount of aglycone in isoflavone plus the amount of isoflavone aglycone)] is 2.5/1 to 25/1, and the amount of said isoflavone aglycone in said composition is 0.5% to 20% to the total amount of aglycone in said composition.
