摘要
研究利用乙醇连续回流法和超声波技术提取玉米醇溶蛋白的工艺,通过单因素试验和正交试验取得的最佳工艺条件为:采用65%乙醇为溶剂,料液比为1∶6,先进行30min超声处理,然后在40℃下提取3h。试验结果为提取率27.54%,产品纯度为83.65%。
Study on the extraction of Zein by ultrasonic wave and solvent refluxing. The factors of the extraction were studied by mono- factor analysis and the optimum technique parameters were determined by orthogonal test. The results were shown： using 65 % ethanol as solvent, ethanol/CGM ratio 1 ： 6, treatment by ultrasonic wave for 30min at first, and then extract at 40℃ for 3h.Extraction rate is 27.54% ,and purity of the product is 83.65%.
