用酶组合技术制备水解明胶的研究

Preparation of Gelatin Hydrolyzate with AS1. 398 Neutral Protease and Bromelain

本文研究了ASI.398中性蛋白酶和菠萝蛋白酶法制备水解明胶,初步探讨了用酶的组合技术制备小分子量及窄分布水解明胶的可能性。结果表明,酶的不同组合方式是调节产物分子量及分布的极有效手段,菠萝蛋白酶和AS1.398中性蛋白酶组合的先后次序,可以调节产物的分子量,两者以混合方式组合,则可以调节产物的分子量分布。

Thee preparation of gelatin hydrolyzate -with AS1.398 neutral protease, bromelain and their combinations was studied in this paper. The possibility of using enzyme combination technique for preparing gelatin bydrolyzate with low molecular weight(MW) and narrow molecular weight distribution(MDW) was diacussed.lt was resulted that aliening combination methods of enzymes was effective for controlling the MW and MWD of gelatin hydrolyzate. The combination in order of the bromelain and AS1.398 neutral protease could be adjusting the MW, their combination in mixing could be adjusting its MWD, obviously.
