본 연구는 복령 균사체 발효 쌀의 첨가가 된장 발효에 미치는 영향을 확인하고자 수행되었다. 복령 균사체 발효쌀을 이용한 된장을 시판하기 위해서는 15%를 첨가하는 것이 가장 적합하였으며, 90일 동안 숙성시킨 된장의 총 유리 아미노산의 함량은 1,889.17 mg%로 분석되어 대조구에 비해 증가하였다. 복령 균사체 발효 쌀의 필수아미노산은 7종이 분석되었으며, 일반 쌀과 비교했을 때 lysin, threonine, valine, methionin

We investigated changes in doenjang quality upon addition of rice fermented with Poria cocos mycelium. Sensory evaluation showed that rice addition to 15% (w/w) was optimal. The content of free amino acids was 1,899.17 mg% in doenjang fermented for 90 days with P. cocos mycelium. The rice contained seven essential amino acids: leucine, valine, phenylalanine, isoleucine, lysine, threonine, and methionine. The levels of essential amino acids increased after fermentation with P. cocos mycelium. Vitamin A (7.47 RE/100 g), Vitamin D (0.45 mg/100 g), and Vitamin E (5.73 mg/100 g) were detected in the experimental preparation but not in the control. In terms of electron-donating ability, the highest scores were 73.8% (in a water extract) and 76% (in an ethanolic extract) of doenjang fermented with P. cocos mycelium. Nitrite-scavenging ability was higher in the ethanolic extract than in the water extract of rice fermented with P. cocos mycelium.
