摘要
以大豆毛油为原料,添加磷脂酶进行酶法脱胶,通过生产实际应用,确定酶法脱胶工艺参数为:磷脂酶A1和磷脂酶C混合酶用量45 mg/kg,pH 5,加水量2%,反应温度52℃,反应时间2 h。在此条件下,脱胶油磷含量可降至5 mg/kg,精炼成品油总磷含量可降至1.4 mg/kg,非水化磷脂去除率达到99.3%以上,精炼成品油得率可达97.3%。对比特殊脱胶方法,精炼成品油经济效益提高了74.42元/t。
Crude soybean oil was degummed by phospholipase A1 （PLA1） and C （PLC）in plant prac- tice. Under the conditions of enzyme （ PLA1 ＋ PLC） dosage 45 mg/kg, water dosage 2% , pH 5, reaction temperature 52 ~C and reaction time 2 h, the total phosphorus content was less than 5 mg/kg in de- gummed oil and below 1.4 mg/kg in refined oil, the removal rate of nonhydratable phospholipids was above 99.3%, and the yield of refined oil could reach 97.3%. Comparing with special degumming method, the economic benefit of refined oil increased by RMB 74.42 per ton.
