摘要
通过对脱色步骤和沉淀步骤的改进，找到一条玉米醇溶蛋白生产的新工艺。分别研究了脱色、提取和沉淀３个步骤中各种工艺参数对生产的影响，摸索出本工艺的最佳工艺条件：脱色：乙醇回流温度下，萃取５ｈ；提取：温度６０℃，时间２ｈ，乙醇浓度７０％，液固比１０∶１（ｍｌ／ｇ）；沉淀：沉淀温度０℃，沉淀剂与醇溶蛋白浓缩提取液比３０∶１（ｖ／ｖ）。
The decolour ation,extraction and precipitation steps of producing zein from corn gluten were studied and improved.The decolour ation was carried out in the ethanol boil point temperature for 5h. 70% ethanol at a ratio of liquid to solid as 10∶1(ml/g)and at 60℃ for 2h.The precipitation was carried out at 0℃ with a ratio of precipitant to zein extract concentrated as 30∶1( v/v ).
