摘  要:
采用Lipozyme 435脂肪酶在鼓泡反应器中催化脂肪酸酯化,产物经二级分子蒸馏得到高纯度甘油二酯(DAG),然后与葵花籽油通过不同比例混合,研究样品晶型变化、熔融结晶性质、固体脂肪含量、微观结构等理化性质,探索DAG在食品专用油脂领域的应用。结果表明,添加60%DAG(质量分数)的葵花籽油样品性质与焙烤用人造奶油、起酥油产品性质类似,其碘值为90.46 g I2/100g,滑熔点为41.9℃,具有应用于食品专用油脂的潜力。

摘  要:
The high purity(98.1%) diacylglycerol(DAG) was prepared through lipase-catalyzed esterification of fatty acids in a bubble column reactor using Lipozyme 435 followed by a two-step molecular distillation. The DAG was blended with sunflower oil in different ratios,and the iodine value(IV),slip melting point(SMP) and other crystalline properties of the mixtures were detected to explore their potential application in food specialty oils. It indicated that the mixture of 60 wt% DAG with the IV of 90.46 g I2 /100 g,and the SMP of 41.9℃ showed the similar properties of bakery margarine and shortening,which would be promising for application in food industry.
