摘要
以冷榨脱脂油茶籽粕为原料,采用胃蛋白酶水解法对油茶籽多肽的制备条件进行了研究。在单因素试验基础上,应用正交试验确定胃蛋白酶水解油茶籽粕制备油茶籽多肽的最佳工艺条件为:酶解温度40℃,酶解时间3 h,加酶量15 000 U/g,固液比1∶30。在此最优条件下进行验证试验,油茶籽多肽产率达到61.8%。
The preparation conditions of peptides were studied by pepsin- hydrolysis from the cold pressed and solvent - extracted camellia seed cake. Based on the single factor experiments, the optimal hydrolysis conditions were confirmed by orthogonal tests as follows：reaction temperature 40 ~C, enzymatic hydrolysis time 3 h, enzyme dosage 15 000 U/g, solid to liquid 1 ： 30. The yield of peptides was 61.8% under the optimal process.
