摘　　要：利用新型磷脂酶LecitaseUltra进行了菜籽油脱胶的研究 ,并应用表面响应法优化了该酶反应条件。在加酶量 2 9.74mg/kg、pH4 .87、温度 4 8.2℃的优化条件下 ,菜籽油含磷量从 15 0 6mg/kg能降到 5mg/kg以下。Enzymatic vegetable oils degumming by phospholipase is an international leading process of oil degumming,which is economical,highly efficacious and stable,gentle and environment-friendly.rapeseed oil degumming by a novel phospholipase,Lecitase Ultra,was studied.The optimum operation parameters of this enzyme are decided by a response surface approach:the enzyme dosage 29.74 mg/kg,the pH 4.87,the temperature 48.2℃.The residual phosphorus content of rapeseed oil decreases steadily to less than 5 mg/kg under the optimum conditions.
