研究乙酯化工艺与分子蒸馏工艺结合提取火麻油多不饱和脂肪酸，对火麻油多不饱和脂肪酸乙酯产物的分子蒸馏条件进行了初步研究。乙酯化工艺结果表明，采用无水乙醇添加量80 mL、NaOH 添加量1％、反应温度70℃、反应时间30 min 时，火麻油脂肪酸乙酯得率最高且火麻油多不饱和脂肪酸（PUFAs）保留最完整。分子蒸馏结果表明，真空度为2．0 Pa、蒸馏温度为90℃时，具有较好的富集效果，火麻油多不饱和脂肪酸乙酯含量提高到82．09％，回收率为79．28％。多级分子蒸馏的实验表明，经过4级蒸馏后，火麻油 PUFAs 乙酯含量上升到87．91％，回收率为53．91％。

The polyunsaturated fatty acids (PUFAs)were extracted from hempsee d oil by combined technology of ethyl esterification and molecular distillation.The molecular distillation conditions of the product were studied.The results of ethyl esterification showed that when alcohol amount 80 mL, NaOH 1 %,temperature 70 ℃,reaction time 30 min,the yield of hempseed oil fatty acid ethyl ester was the highest and the form of PUFAs was best preserved.The results of molecular distillation showed that when vacuum degree 2.0 Pa,distillation temperature 90 ℃,it had a good enrichment effect.The content of PUFA ethyl esters raised to 82.09%,recovery rate was 79.28%.The results of multi -stage molecular distillation showed that after four stages molecular distillation,the PUFA ethyl esters were purified up to 87.91 %,recovery rate was reduced to 53.91 %.
