Diacylglycerol synthesis by enzymatic glycerolysis: Screening of commercially available lipases

, 2005
Seven lipases were screened for their ability to synthesize DAG in the glycerolysis of rapeseed oil. In batch reactions with free glycerol, the lipase carrier was of great importance for catalysis.

瓜蒌籽甘油二酯油的酶法甘油解制备研究 "reparation of diacylglycerol from Trichosanthes kirilowii seed oil by enzymatic glycerolysis"

Zhongguo youzhi
为了优化瓜蒌籽甘油二酯（DAG）油制备工艺，提高DAG工业化产量，以脂肪酶为催化剂，采用酶法甘油解法制备瓜蒌籽DAG油，通过单因素试验探究了反应时间、脂肪酶添加量、醇油质量比对DAG含量的影响，通过响应面法优化反应条件，并对酶法甘油解反应前后瓜蒌籽油的脂质组成、脂肪酸组成和基本理化指标进行分析。结果表明：瓜蒌籽DAG油最佳制备条件为反应时间12.5 h、醇油质量比1∶ 10、脂肪酶添加量6.5%（以醇油总质量计），该条件下所得瓜蒌籽DAG油的DAG含量为60.60%，其中1,3-DAG含量为45.97%，
