摘要
对碱法提取大米蛋白进行了研究,采用正交试验优化了工艺条件,结果表明:影响米蛋白提取率的主次因素顺序为:料液比>碱液浓度>提取时间>提取温度,最佳工艺条件为:料液比1:10,碱液质量分数0.35%,提取时间6 h,温度40℃,在此条件下,大米蛋白提取率可达88.87%。
The alkaline extraction of rice protein was studied by an orthogonal test.The results show that the extraction rate of rice protein is mostly influenced by ratio of solid-liquid,followed by conditions of NaOH,extraction time and extraction temperature.The optimum process parameters are ratio of solid-liquid 1：10,quality score of NaOH 0.35%,extraction time 6 h and extraction temperature 40 ℃.Under these conditions,the extraction yield is up to 88.87%.
