<P>PROBLEM TO BE SOLVED: To breed a Koji mold having the protease productivity of ≥1,100 U/g Koji and the glutaminase productivity of ≥2.0 U/g Koji, and to provide soy sauce having a high nitrogen utilization ratio, total nitrogen and glutamic acid content using the Koji mold. <P>SOLUTION: The Koji mold is obtained by irradiating a strain belonging to the genus Aspergillus with a heavy ion beam and separating the Koji mold having protease productivity of ≥1,100 U/g Koji and glutaminase productivity of ≥2.0 U/g Koji from the irradiated strain or a cultured product thereof. The resultant Koji mold is inoculated into raw materials for soy sauce Koji and cultured to prepare the Koji, and the resultant Koji is used to carry out preparation for brewing. As a result, the soy sauce is obtained. <P>COPYRIGHT: (C)2009,JPO&INPIT |
