摘　　要：本文应用酶学分析方法研究了盐度对刺参消化道内各种消化酶活力的影响。蛋白酶活力测定采用福林-酚法,脂肪酶活力测定采用水解法,淀粉酶活力和纤维素酶活力测定采用水杨酸显色法。试验结果表明,除脂肪酶外,盐度对消化道内消化酶活力具有显著影响(P<0.05)。淀粉酶和蛋白酶在盐度30时活力最大,而纤维素酶在盐度26时活力最大。Effects of salinity on enzymes activities in digestive tract of Apostichopus japonicus were analyzed.The activities of protease,lipase,amylase and cellulase were determined by Folin-phenol method,turhidimetric method and colorimetric assay of salicylic acid, respectively.The results showed that salinity had significant effects on the activities of digestive enzymes except lipase.The optimum salinity of protease and amylase was 30, while the optimum alinity of cellulase was 26.
