| Abstract: | The preparation of collagen by enzymolysis of tilapia scale powder with alcalase was studied in this paper. With extraction rate of collagen as index,the optimum enzymolysis conditions were obtained through single factor experiment and orthogonal experiment as follows.the mass fraction of 100 mesh tilapia scale pow- der was 7% ,enzymolysis temperature was 65 ℃ ,enzymolysis pH value was 8.5,alcalase amount was 0.05 AU ·g-1, enzymolysis time was 2.0 h. Under above conditions,the extraction rate of collagen reached 95.79 %. |
