摘　　要：以溶剂浸提法制取的富士苹果籽油为原料,探讨了磷脂酶A_1在苹果籽油脱胶中的应用。设计单因素试验,探讨了加酶量、脱胶时间、脱胶温度、pH以及含水量对苹果籽油脱胶效果的影响;并通过正交试验进行了磷脂酶A_1用于苹果籽油脱胶的优化。结果表明:苹果籽油理化指标符合一般植物油的标准;磷脂酶A_1用于苹果籽油脱胶,在加酶量45 mg/kg、脱胶时间3.5 h、脱胶温度50℃条件下,脱胶效果最佳,最终含磷量降低至7.8 mg/kg,达到植物油脱胶标准。Using apple seed oil obtained by solvent extraction as material, the degumming processe by phospholipas A_1 was discussed. The effects of enzyme amount,degumming time,degumming temperature,p H,and water content on the degumming efficiency of apple seed oil were investigated by single factor test. The enzymatic degumming parameters were optimized by orthogonal test. The optimum degumming conditions were obtained as follows：the amount of phospholipase A_1 was 45 mg/kg,degumming time was 3.5 h,and degumming temperature was 50 ℃. Under these conditions,the phosphorous content was decreased to 7.8 mg/kg,which correlated well with the requirement limit of phosphorous content for vegetable oils degumming.
