Title:
PRODUCTION OF KOJI
Document Type and Number:
Japanese Patent JP2000060536
Kind Code:
A
Abstract:
To obtain koji richer in γ-aminobutyric acid(GABA) having hypotensive activity by anaerobic treatment of the original koji.
The objective koji is obtained by anaerobic treatment of the original koji which is afforded by growing filamentous fungi (e.g. Monascus pilosus, Aspergillus oryzae) in a starch-based stock; wherein the anaerobic treatment is performed for example, by holding the original koji in a carbon dioxide gas atmosphere. Steaming treatment of the koji subjected to the anaerobic treatment increases the content of GABA in the koji and deactivates a GABA splitting enzyme as well, thereby affording the aimed koji stably leaving GABA in high concentrations therein, therefore being preferable.
