摘要
以脂肪酶Novozym 435为催化剂,正己烷为溶剂,探讨了以大豆磷脂为原料制备溶血磷脂的影响因素,并得到最佳工艺条件:底物浓度为25%(W/V)、加水量20%、反应温度为51℃、加酶量为6.6%。该条件下磷脂水解后的酸值可达到77.8 mgKOH/g。
The hydrolysis of soybean phospholipid by lipase Novozyrn 435 in hexane was studied, and the optimum conditions of reaction were investigated by response surface experiment. The results showed that the optimum conditions were as follows： substrate concentration 25% （ W/V）, water content 20%, reaction temperature 51 ℃, lipase dosage 6.6% . Under the conditions, the acid value of product was 77.8 mgKOH/g.
