【Abstract】 The preparation of gelatin from bovine bones with AS 1.398 neutral proteinase was studied. Further investigations were conducted on the effects of the temperature, time, enzyme concentration and the ratio of water to bones on the gel strength. The experimental results showed that the proper reaction conditions for preparation of gelatin with high gel strength from bovine bones by means of enzymatic processing have been obtained. 更多还原
