【摘要】 通过测定婴幼儿配方奶粉乳蛋白酶解液的氮溶指数表征蛋白的酶解程度,确定蛋白酶水解乳蛋白的最佳酶解工艺条件。使用蛋白酶ProteaseM"Amano"G酶解婴幼儿配方奶粉中乳蛋白的最佳酶解工艺条件为酶解时间3h、酶浓度1.5%、pH7.0、酶解温度45℃。在此条件下,氮溶指数为45.93%。更多还原

【Abstract】 Optimal condition for enzymatic hydrolysis of milk protein in infant formula was investigated through evaluating nitrogen soluble index,an indictor of enzymatic hydrolysis degree,in hydrolysate solution.The optimal hydrolysis condition for protease M "Amana" G was 3 h of hydrolysis,1.5% of enzyme-substrate ratio,45 ℃ of reaction temperature,and pH 7.0.The nitrogen soluble index was 45.93% under this optimal condition.更多还原
