摘要
探讨了采用脲包法富集被孢霉菌丝油脂中γ-亚麻酸过程中原料与尿素和溶剂配比、结晶温度、包合时间及包合次数等主要操作条件对γ-亚麻酸富集效果的影响.实验研究结果表明:通过二次包合处理,菌丝油中γ-亚麻酸含量由6.12%提高到73.66%,富集了12倍.
<Abstrcat> γ-Linolenic acid in the mycelium oil of Mortierella can be enriched by the method of urea occlusion. Some factors effecting on the enrichment, such as occlusion time, crystallizing temperature, and the mixture ratio of urea to mycelium oil and methanol, have been discussed in detail. The content of γ-linolenic acid in the mycelium oil can be raised from 6.12% to 73.60%.
