摘　　要：以冷榨菜籽油为原料,用海藻酸钠-明胶固定化磷脂进行脱胶,通过单因素实验及旋转正交实验得出反应最佳条件为:固定化酶添加量240mg/kg,反应的起始pH为5·6,反应温度57℃,反应时间6h。在上述最优条件下进行脱胶实验,菜籽油含磷量从352mg/kg降到4·12mg/kg,脱胶效果好。The immobilized PLA by sodium alginate and gelatin was used for rapeseed oil by cold-pressing degumming through single factor test and rotary orthogonal test.The optimal reaction conditions were determined：the immobilized enzyme dosage was 240mg/kg,initial pH was 5.6,the reaction temperature was 57℃,the reaction time was 6h.The residual phosphorus content of rapeseed oil decreased steadily to less than 4.12mg/kg under the optimum conditions.The non-hydration phospholipid could be removed effectively.
