酶解蚕蛹蛋白及其应用研究
Study on Hydrolysis of Silkworm Chrysails Protein by Enzyme and lts application
【摘要】 本文首先对胰蛋白酶水解蚕蛹蛋白的最佳条件进行了选择,结果为酸解固液比20:70、酶作用量0.5%、酶解温度45℃、酶解时间5小时、酶解PH值7.0;接着针对胰蛋白酶较低的水解率进行了提高其水解能力的研究,发现采用脱脂、浸泡、酶-酸联合水解等处理可大大提高蚕蛹蛋白的水解率,最后利用β-环状糊精的包理作用和蜂蜜的掩盖作用,制得了一种氨基酸含量丰富的委蛹复合氨基酸口服液.
【Abstract】 This article first selected the appropriate conditions of hydrolysising of silkworm chrysalis protein by trypsin, the result was: ratio of substrate and water 20:70, the amount of enzyme 0. 5%, temperature 45℃, time 5hr, PH 7. 0. Then the im-provement of toypsins hydrdytic ability was studied, treatments including degrease,soakini and combined hydrolysis by enzyme and acid could increase the hydrolytic rate greatly. And we got a drink rich in amino acids through β-CD and honey.
