<p>PURPOSE:To prepare a KOJI from which crude fats and oils and an odor component are extracted and removed, and simultaneously sterilized, by bringing a KOJI prepared by a conventional procedure into contact with pressurized carbon dioxide at >= constant pressure in a specific temperature range. CONSTITUTION:A KOJI prepared by a conventional procedure is brought into contact with carbon dioxide in a liquid, gaseous, or super critical state at -20- 80 deg.C at >=10 bar pressure. In this case, the koji is predried into 5-29wt% water content more effectively. After being treated for a given time, the KOJI is separated from carbon dioxide, and taken out sterilizedly. By this method, crude fats and oils and an odor component are reduced, and various bacteria are simultaneously sterilized.</p> |
