| 中文摘要: |
| 采用正交实验设计对尿素包合法富集牡丹籽油不饱和脂肪酸工艺进行优化。考察了包合反应中尿素与乙醇质量体积比、包合温度、包合时间对产品中α-亚麻酸含量的影响。结果表明：最佳工艺条件为尿素与95%乙醇质量体积比3∶?9、包合温度0?℃、包合时间15 h，尿素包合后α-亚麻酸含量达64.95%。尿素包合法可有效地富集牡丹籽油中的不饱和脂肪酸，并且可以提高α-亚麻酸的含量。 |
| 英文摘要: |
| Orthogonal experimental design was used to optimize the unsaturated fatty acid enrichment of peony seed oil by urea inclusion method. The effects of urea-ethanol ratio, inclusion temperature and inclusion time on the α-linolenic acid content were investigated. The results showed that the optimal process conditions were obtained as follows: urea-95%ethanol ratio 3∶?9, inclusion temperature 0?℃ and inclusion time 15 h. Under these conditions, the content of α-linolenic acid reached 64.95%. The urea inclusion method could effectively extract unsaturated fatty acids from peony seed oil, and increase the content of α-linolenic acid. |
