摘要
本文报道了以猪油与菜油,棕榈油与菜油,乌桕油与菜油以及猪油为原料的酯交换法生产人造奶油、起酥油中间试验时,检验酯交换效果的研究。作者按IUPAC方法,用胰酯酶对油样进行部分水解,从而测定分布在甘油三酯中2—位的脂肪酸,并用线性回归方法,将其与样品的总脂肪酸组成相比较。结果表明经酯交换反应后随机化的油脂,其2—位脂肪酸与总脂肪酸组成有着良好的一致性和良好的线性相关。在42个酯交换油样品中有39个样品的酯交换效果是十分满意的。
The research on determination the interesterification effect of medium scale production test for producing margarine and shortening by interesterification method with lard and rapeseed oil,palm oil and rapeseed oil,stillingic oil and rapeseed oil,as well as lard has been reported.According to IUPAC method to hydrolysis the triglycerides of the oil samples with pancreatic lipase and then analysis the fatty acids distributed on the 2-position of the triglycerides.Compared them with the composition of the total fatty acids by linear regression method.The results indicated that there are a good identity and a good correlation between 2-position fatty acids and total fatty acids composition in interesterfied random oils and fats.Among the 42 samples the interesterification effect of 39 samples are satisfactory.
