| 摘 要： | 为了提高鱼油中生理活性组分ＥＰＡ和ＤＨＡ的含量，以鱼油乙酯为原料，将其与饱和的尿素－乙醇溶液进行包合作用，而使鱼油中的饱和脂肪酸成结晶析出，以达到预浓缩的目的。随着尿素与鱼油乙酯摩尔比的增加，或结晶温度的降低，容易获得ＥＰＡ和ＤＨＡ含量在７０％以上的制品。

| Abstract: | To improve content of physiologically active substances EPA and DHA from fish oil, using fish oil ethyl esters as materials and mixing them with saturated urea ethanol solvent, saturated fatty acid esters will be clathrated by urea and are then separated away in crystal forms. With the increasing of the mole ratio between urea and fish oil fatty acid ethyl esters, or with the decreasing of the crystallization temperature, products which contain EPA and DHA over 70 % can be easily prepared. |
