Monascus속 곰팡이를 이용한 메주의 효소류 활성을 조사하기 위하여 M perpureus와 M. pilasus의 두 균주를 사용하여 쌀 메주와 콩 메주의 효소활성을 조사하였다. M Manascus 백미 및 백미붙말 메주의 효소휴 활성은 전반 적으로 M pilasus를 사용한 경우에 높았다 Prote잃e 활 성응 쌀 분말 메주가 남알상태의 쌀 메주에 비하여 높 았으나. (-amylase, -amylase 및 glucoamyJa않는 날알 쌀 메주

This study was conducted to investigate the effect of rice powder m tile enzyme (protease, -amylase, -amylase and glucoamylase) activities of soybean meju fermented by Monascus prepureus and Monascus pilosus. The activities of the enzyme in the rice meju and the soybean meju fermented by M. pilosus were higher than those by M. perpureus. Protease activity of powdered rice meju was higher than that of granular rice meju, while -amylase, -amylase and glucoamylase activities were higher in granular rice meju. Protease activity in soybean meju fermented by adding of the cultured medium of Monascus strains(CMM) as a seed inocula were higher than those of the rice powder meju, while -amyulase, -amylase and glucoamylase activiities were lower than those of soybean meju by CMM. The concentration of rice powder to show maximum protease activity in soybean meju was also 10% against steamed soybean. But -amylase activity of soybean medju by the CMM added 2% powdered rice showed lower but the activity increaed with an increase in powdered rice, whereas -amylase and glucoamylase activiities decreased with an increase in powdered rice. Protease activity of soybean meju fermented by 10% rice meju fermented by M. pilo년 as a seed inocula was higher than that of the meju fermented by Aspergillus oryzae, whereas -amylase and glucoamylase activities of the soybean meju showed less than 50%.
