Abstract
To extract insoluble proteins of soymilk residue by microorganism, the soymilk residue was treated with crude enzyme solution from Aspergillus oryzae. Optimum conditions of pH, temperature and digestion time were determined, and amino acid composition of the extract was analyzed. The optimum pH for the extraction was 7.5, and the maximum extraction was obtained at
두유박에 함유되어 있는 불용성 형태의 단백질을 Aspergillus oryzae가 생산하는 효소를 이용하여 가용성 형태의 단백질로 용출시키기 위하여 효소작용 최적조건으로서 pH, 온도 및 소화시간을 결정한 다음 추출액의 아미노산 조성을 본 결과 두유박 용출을 위한 최적 pH는 7.5, 최적온도는
