利用双氧水的氧化性对大豆分离蛋白进行了化学改性研究.分别考察了双氧水用量、反应温度和反应时间等单因素变化对改性效果的影响,并在此基础上设计了正交试验进行参数的优化.试验结果表明,双氧水用量和反应温度是两个关键性因素.最佳反应条件为:20%双氧水加入量为2.4 mL/g蛋白,反应温度为40℃,反应时间为35 min.

Soy protein isolate was chemically modified by oxidation of H2O2. The effects of single factor variation such as dosgage of H2Q2, reaction temperature and time on modification efficiency were investigated, respectively. On the base of that, orthogonal tests were designed for optimization of parameters. The results illustrated that the dosage of H2O2 and reaction temperature were two key factors.The optimum parameters were that the dosage of H2O2(concentration 20% ) was 2.4 mL/g protein,...
