摘要
以水化脱胶大豆油为原料,选用磷脂酶lecitase ultra进行小样实验,单因素实验结果表明最优的反应条件为:酶添加量30 mg/kg,加水量3.0%,p H5.0,反应温度50℃,反应时间5 h。在此基础上,进行了800 t/d连续式酶法精炼工厂化实验,生产实践表明酶法成品油得率较化学精炼法提高0.8%,经济效益明显,同时对比了酶法精炼成品油与化学精炼成品油的理化指标及稳定性,两者无明显差异。
The laboratory experiments were conducted with hydration degumming soybean oil as raw material by the phospholipase lecitase ultra. The single factor results showed that the optimum reaction conditions were as follows：enzyme dosage of 30 g/t oil,water content of 3.0%, pHS.0,reaction temperature of 50 ℃, reaction time of 5 h.Under these conditions, the continuous enzymatic degumming production experiments were carried out on the 800 t/d production line.The results showed that the oil yield increased by 0.8% compared to the chemical method, it showed obvious economic benefits.The physical and chemical indexes and stability of refined oils produced by both methods were compared, and the results showed no obvious difference.
