葵花籽油制备共轭亚油酸的研究

Study on preparing of Conjugated linoleic acid from sunflower oil

葵花籽油是为数不多的高含亚油酸的油脂之一,是很好的生产共轭亚油酸的原料。探讨了反应时间、加碱量等对葵花籽油制备共轭亚油酸共轭化转化率的影响。通过正交试验,确定了最佳试验条件,获得了90%以上的共轭化转化率。

Linoleic acid content of sunflower oil is high. It is good material for Conjugated linoleic acid. Conjugated linoleic acid has good physiological function. The reactive mechanism of conjugation catalyzed by alkali and the affecting factors such as time and amount of alkali were discussed. The optimal conditions were obtained by orthogenesis test, which provided a conjugation yields above 90%.
