FERMENTED SOYBEAN AND METHOD FOR MANUFACTURING FERMENTED SOYBEAN

摘要

The present invention provides a method for manufacturing fermented soybean that contains a high level of γ-aminobutyric acid and isoflavone agylcone and that is readily edible with little bitterness. The present inventors devised a manufacturing method capable of manufacturing fermented soybean that contains a high level of γ-aminobutyric acid and isoflavone agylcone and that has little bitterness by using an aerobic solid culture that uses at least two species of microorganisms belonging to the Rhizopus genus, and by furthermore shifting the incubation temperature.
