采用碱溶酸沉淀法从大米渣中提取蛋白质 ,通过正交试验研究了提取工艺条件 .确定大米蛋白质的等电点 p H值为 3.9,最佳的碱提条件为 p H值为 1 2 ,温度 4 0℃ ,时间 2小时 ,料液比 1∶ 1 2 .在此条件下蛋白质提取得率为 4 9.9% ,产品蛋白质含量为 71 .1 %

Protein for foods was extracted from rice dregs in alkalinous condition. The process conditions of extraction were studied by perpendicular test. The equivalent charge point of rice protein was determined as pH 3.9. The best conditions of extraction were as follows: pH is 12, temperature is 40 ℃, time is 2 h and the ratio of rawmaterial to water is l∶12. In such conditions the ratio of protein gained...
