| 中文摘要: |
| 为了提高从元宝枫籽油中富集神经酸的纯度和收率，将元宝枫籽油皂化制备混合脂肪酸，然后用不同溶剂溶解混合脂肪酸并进行低温结晶，优化结晶溶剂、料液比和结晶时间等工艺参数。结果表明，当元宝枫籽油混合脂肪酸与乙醇以质量体积比1∶ 3混合，在-40 ℃下低温结晶4 h后，得到的结晶中神经酸含量为13.11%，收率为65.48%，终产品中神经酸含量比元宝枫籽油中原有神经酸含量提高了1倍多。 |
| 英文摘要: |
| In order to improve the purity and yield of the nervonic acid enriched from Acer truncatum Bunge. seed oil, the Acer truncatum Bunge. seed oil was saponified to prepare mixed fatty acids, and then the mixed fatty acids were dissolved in different solvents and crystallized at low temperature. The conditions of crystallization solvent type, ratio of mixed fatty acids to solvent and crystallization time were optimized. The results showed that when the mixed fatty acids were mixed with ethanol in a mass-volume ratio of 1∶ 3, and crystallized for 4 h at -40 ℃, the content of nervonic acid in the crystal was 13.11%, the yield was 65.48%, and the content of nervonic acid in the final product was more than twice as high as that in Acer truncatum Bunge. seed oil. |
