摘要
实验采用中空纤维超滤器(MB10KD)、保温系统及回流系统组建形成小型连续化酶-膜反应器;采用胰蛋白酶作为水解用酶,连续化制备牛乳水解蛋白。通过对得到的水解蛋白进行小鼠动物消化实验,发现利用连续化酶-膜反应器水解制备的水解蛋白在实验小鼠的胃液及肠液中的三氯乙酸可溶性氨基氮含量最高,实验结果表明此牛乳水解蛋白在小鼠胃中、肠中的消化率均明显高于原牛乳以及传统的婴儿配方乳。
Infant formulas,continuously produced in an enzyme-membrane reactor,was investigated its digestibility in rats.Trypsin was used to hydrolyze whole milk protein.After the rat eat the infant formulas,the gastric juice and intestine juice of rat was collected at certain time to be used to determine the soluble amino nitrogen.The results showed that the infant formulas was more efficient to be digestive than raw milk and traditional infant formulas.
