溶剂分提法去除鱼油中高凝固脂的研究

利用溶剂分提技术，对鱼油中高凝固点的组分(固脂)进行分提。研究不同溶剂鱼油比(0.5、1.0、1.5、2.0、2.5)、不同温度(－8、－11、－15、－20°C)对液态油得率、熔点，以及EPA和DHA含量的影响。结果表明，运用溶剂分提技术，在溶剂鱼油比为1.0、1.5，温度－8°C、－11°C；溶剂鱼油比为1.5、2.0、2.5，温度－15°C，－20°C，可以有效地脱除鱼油中的固脂，液态油的得率可达80％以上，且液态油中EPA和DHA含量有所提高。

Isolation of High

A new process of isolation high－solidified fat from fish oil bysolvent was investigated in this study.The effect of different solvent fish oil rate(0.5， 1.0 ， 1.5， 2.0 ， 2.5 )and different temperature(－8° C， －11° C， －15° C， －20° C)on liquid oil obtain rate， melting point and contents of EPA and DHA was main studied.The results showed that high－solidified－point fat could be isolated by solvent isolation when solvent fish oil rate was 1.0 and 1.5，temperature was－8℃ and－11℃,also when solvent fish oil rate was 1.5，2.0 and 2.5，temperature was－15℃ and－20℃ .Liquid oil obtain rate could above 80％，and contents of EPA and DHA become highly。
