摘    要:植物油的酶法脱胶是一种新的大豆油脱胶方法。利用新型微生物磷脂酶Lecitase Ultra进行大豆油脱胶的研究,探讨了若干操作参数对大豆油脱胶效果的影响,确定了该酶较优的反应条件:反应时间200 min,加酶量25 mg/kg,pH值4.8,温度46~48℃,大豆油含磷量能降到4.7 mg/kg。结果表明,Lecitase Ultra应用于植物油脱胶效果好且稳定,是一种更适宜于工业化应用的酶种。

关 键 词:磷脂酶  大豆油  脱胶

Abstract:Enzymatic degumming of soybean oil was studied with Lecitase Ultra,a new microbe enzyme.Effect of operation parameters on degumming performance was discussed.The optimal condition was chosen as reaction time of 200 min,enzyme dosage of 25 mg/kg and reaction temperature at 46~48℃ with pH 4.8,and the residual phosphorus content could be decreased to 4.7 mg/kg.
Keywords:phospholipase  soybean Oil  degumming
