摘要
本文研究了大豆分离蛋白水解物中分子量小于10 kDa 的混合肽与锌合成制备金属蛋白盐的工艺条件。实验结果表明,获得螯合物的最佳条件是:多肽反应液浓度4%,肽锌质量比2.25:1,pH值为5.0,温度60℃,时间 40min。
Optimum conditions of a new mineral protein salt made by hydrolysis of soy protein isolate, whose molecular weightwas under 10 kDa chelated with Zinc was studied. The results showed that the best conditions for this chelate was: the concentrationof soybean peptide was 4%,the mass ratio of soybean peptide to Zinc 2.25:1 ,temperature 6℃,pH 5.0,and the chelate time40min.
