摘　　要：以乙酯化鱼油为原料,利用分子蒸馏和尿素包合相结合的方法,对鱼油中的EPA、DHA进行分离富集,对富集工艺进行优化。试验结果表明,1级分子蒸馏温度120℃,真空度3Pa,进料速度2g/min,进行5级分子蒸馏;尿素包合条件是:尿素/乙酯化鱼油的质量比2∶1,结晶温度3℃,包合时间18h。经过2次5级分子蒸馏和1次尿素包合,鱼油中EPA和DHA的含量从30.72%提高到83.42%。Experimental parameters were optimized by using ethyl ester fish oil as a raw material. The method of molecular distillation and urea inclusion to combine to enrich the EPA and DHA was studied. The results showed that one level of molecular distillation temperature was 120℃ vacuum of 3 Pa, feed rate at 2 g/min, using five level of molecular distillation; urea inclusion criteria as follows： urea/fish oil mass ratio of 2：1, the crystallization temperature 3 ℃ and inclusion time 18 h. After a second molecular distillation and urea inclusion, the EPA and DHA content could increase from 30.72% to 83.42%.
