酶法制备大豆活性肽的工艺研究

大豆活性肽不仅保持了大豆蛋白质的营养性，而且具有独特的加工功能和生物活性。酶法制备大豆活性肽比酸碱水解法和生物合成法更有优势，酶法制备大豆活性肽的工艺，包括大豆蛋白和蛋白酶的选择、大豆蛋白的预处理、酶水解参数和酶水解方式的确定、水解度的控制、灭酶活方法、精制等操作单元。

Research on Preparing Technology of Active Soybean Peptide by Enzyme

The active soybean peptides not only keep the nutrition of the soybean protein, but also own the special processing and biological functions. Preparing active soybean peptides by enzyme is better than acid-alkali hydrolysis and biological composing, so in this passage, studies on the technique of preparing the active soy- bean peptides by enzyme, which includes the choice of soybean protein and protease, the preprocessing of soybean protein, finding out the parameter of hydrolysis and the way of hydrolysis by enzyme, the method of controlling hydrolysis and killing the activity of enzyme, further processing and so on .
