PROCESS FOR PRODUCING FERMENTED FOODS RICH IN gamma -AMINOBUTYRIC ACID AND FREE AMINO ACIDS

摘要

Fermented soybean products containing gamma -aminobutyric acid at a high concentration are produced by fermenting soybean with the use of Tempe molds. Further, fermented soybean products containing gamma -aminobutyric acid and free amino acids at high concentrations are produced by fermenting soybean with the use of Tempe molds and treating anaerobically. Furthermore, fermented cereal products containing gamma -aminobutyric acid and free amino acids at high concentrations are produced by fermenting cereals with the use of Koji molds and treating anaerobically. As the Tempe molds or Koji molds as described above, use can be preferably made of molds belonging to the genus Rhizopus such as R. oligosporus and R. oryzae.
