液体脂肪酶催化制备甘油二酯油连续化工艺研究 Continuous preparation process of diacylglycerol oil catalyzed by liquid lipase
旨在强化酶催化大豆油的甘油解反应为甘油二酯油的工业化生产提供技术支持,以大豆油和甘油为原料,液体脂肪酶为催化剂,利用微通道反应器制备甘油二酯油。通过单因素实验考察了液体脂肪酶用量、大豆油与甘油质量比、反应温度、反应时间对反应粗产物中甘油二酯质量分数的影响,设计中试放大实验考察工艺的稳定性,并采用分子蒸馏对中试粗产物进行纯化。结果表明:甘油二酯油制备的最佳工艺条件为液体脂肪酶(10 000 U/mL)用量3%(以大豆油质量计)、大豆油与甘油质量比10∶ 1、反应温度50 ℃、反应时间9.0 s,在此条件下粗产物中甘油二酯的质量分数达44%;经中试实验放大后,粗产物中各组分(游离脂肪酸、单甘酯、甘...
