Abstract: The mullet defatted by lipase was studied in this paper. The conditions of the hydrolytic reactions were determined by the orthogonal test L9(33). According to the defatted ratio, the experimental results showed that the optimal conditions areenzyme concentration 40 U/ml, reaction time 40 min and the ratio between material fish and enzyme solution 1:5, the optimal temperature 32℃ and pH8.7, with the defatted ratio of the surimi of mullet as 75.6%, but that of fish fillet lower, only 55.4%.

Key words: lipase, Mugil cephalus Mullet, defatted ratio
