摘　　要：研究了CTAB/异辛烷/正辛醇反胶团体系萃取分离菜籽蛋白质的前萃工艺。考察了水相pH、离子强度、原料加料量、萃取时间对菜籽蛋白质萃取率的影响,最后采用了四因素四水平正交实验,得出反胶团法分离菜籽蛋白质的前萃最优工艺条件为:菜籽粉加入量为0.6 g,KCl浓度0.09 mol/L,pH值7.0,萃取时间80 min。在最佳工艺条件下,前萃率可达70.19%。In this paper, we made research on processing of the forward extraction of rapeseed protein by reverse micelles. The rapeseed powder , the intensity of the ion , the value of pH and the extraction time , were studied , and the results were explained in microcosmic structrure of reverse micelles. It proved that the optimum condition of forward extraction is： 0.09mol/lKCl, pH7.0, extraction time 80min. Under this condition,the protein extraction is 70.19%.
