This experiment took lobster heads and shells as the main raw material to obtain the shrimp seasoning sauce by enzymolysis pretreatment. Based on the result of single factor test, the best enzymolysis condition and optimum flavor prescription were determined by the result of orthogonal experiment. According to the result, the amino - nitrogen content, enzyme concentration as weU as the temperature and time for enzymolysis were optimized as 34.68mg/g, 3% ,7h and 60℃ respectively. The optimum flavor prescription was concluded as follows: enzyma...
