초록
고등어와 정어리의 보통육과 혈합육의 각 조직에 분포하는 단백질분해효소의 최적활성조건을 구명하고 열안정성과 저온저장중의 활성변화 등을 비교
Proteolytic activity of the tissue extracts from the muscle of mackerel, Scomber japonicus, and sardine, Sardinops melanostcta, was comparence with referenced to the optimum reaction condition. Thermal stability and change of proteolytic activity of the tissue extracts during storage were investigated. The existence of acid, weak acid and alkaline proteinase was identified in the ordinary and dark muscle of the mackerel and sardine. Specific activity of acid proteinase was stronger than weak acid or alkaline proteinase in the both fish. The proteolytic activity of the tissue extracts on the optimum reaction condition was: ordinary muscle of mackerel, 0.12 nM-Tyr. eq./mg-prot. /min. at pH 3.0 and
