【摘要】 通过正交实验,确定了利用Alcalase从燕麦麸皮中提取燕麦蛋白及YD-303处理燕麦蛋白提取液脱色的工艺条件。结果表明,Alcalase提取燕麦蛋白的最佳条件为:加酶量(E/S)为3%,pH为8.5,料液比为1:22,温度为65℃,提取时间为180min。YD-303处理燕麦蛋白提取液脱色最优工艺为:添加量(g/mL)为1.5%,pH为3.5,温度为40℃,脱色时间为75min。更多还原

【Abstract】 Adopting orthogonal experimental design,the optimum conditions for oat protein extraction from oat bran and decolouring technology were determined.The results showed that the optimum process conditions with Alcalase were as follows:enzyme dosage(E/S) 3%,enzymolysis pH8.5,material-water ratio 1:22,enzymolysis temperature 65℃ and enzymolysis time 180min.The optimum decoloration conditions with YD-303 were as follows:quantity of activated carbon 1.5%,pH3.5,temperature 40℃,adsorption time 75min.更多还原
