摘　　要：利用磷脂酶将花生油中的非水化磷脂转化为水化磷脂是一种代替化学脱胶的新方法。采用新型磷脂酶Lecitase Ultra对花生油进行脱磷脂研究,确定了该方法的反应条件:酶添加量25 mg/kg,反应温度55℃,pH值5.0,反应时间2 h。在此条件下花生油磷脂残留量降到4.2 mg/kg。Using phospholipase to transform nonhydratable phospholipids in peanut oil into hydratable phospholipids is a new method instead of chemical degumming. In this paper,the technology using Lecitase Ultra to remove nonhydratable phospholipids in peanut oil was studied,and the optimal reaction conditions were obtained. When the enzymatic degumming reaction was conducted at 55°C for 2 hours with the enzyme additive amount as 25 mg / kg and the pH value as 5. 0,the phospholipids content could be dropped to 4. 2mg / kg.
