METHOD FOR PREPARING CHEONGGUKJANG HAVING INCREASED POLYGLUTAMIC ACID CONTENT

摘要

The present invention relates to a method for preparing cheoggukjang (fast-fermented bean paste) having increased polyglutamic acid content. The method comprises the following steps: (A) washing and steaming soybeans; and (B) inoculating Bacillus subtilis strains isolated from rice straw into the steamed soybeans and fermenting the same. Accordingly, high molecular weight polyglutamic acid having the molecular weight of 200 kDa or more is produced, and the content of generated polyglutamic acid is increased 1.5 to 2.5 times the content of existing polyglutamic acid.;COPYRIGHT KIPO 2017
