摘要
研究了用双酶水解技术对马氏珠母贝肉进行水解的条件。结果表明：枯草杆菌中性蛋白酶：在ｐＨ６．５、温度４０℃、酶浓度３×１０３Ｕ／ｍｌ、Ｋ＋浓度０．１２％、水解时间３．０ｈ后；再用胃蛋白酶水解：ｐＨ３．０，温度６０℃，酶浓度４．５Ｕ／ｍｌ、水解时间３．０，最适底物浓度为原料与水比例１：３进行水解，蛋白质水解率为６６．２％。水解液可用于生产海鲜调味料及功能性蛋白饮料。
In this paper ,we studied useing proteinase to hydrolyze Pinctada martensii meat. The optimal conditions for hydrolysis by enzyme method were : B.Subctilis neutral proteinase hydrolyzed at pH6.5,temperature 40℃, enzyme consistency 3×103U/ml , K+ concentraction 0.12%,and time 3.0h.Then add stomach proteinase at pH3.0,temperature 60℃, enzyme consistency 4.5U/ml , and time 3.0h, The degree of hydrolysis of mussel meat is 66.2% by this method. The hydrolysis liquid can be used to make high quality seafresh seasoner and fundational protein drink .
