摘　　要：讨论了不同温度的有机溶剂分级提取对鳀鱼鱼油得率、脂肪酸组成及EPA、DHA含量变化的影响。经15℃干法分级提取的液态鳀鱼鱼油,在设定的4种温度下,液态鳀鱼鱼油得率均随溶剂量的增加而提高;在相同溶剂量的情况下,随着分级提取温度的降低,液态鳀鱼鱼油得率呈下降的趋势。有机溶剂分级提取对14碳短碳链的饱和与不饱和脂肪酸及16碳、18碳的饱和脂肪酸的脱除效果是明显的,但对脱除20碳、22碳的长碳链饱和脂肪酸的效果不明显。在4种试验温度下,EPA和DHA的总量分别为29.88%、31.74%、35.27%和41.80%,高出美国阿拉斯佳深海鱼油对应总量(28.76%)的1.12%～13.04%。This paper studies on the influence of organic solvent abstract temperatures on Engranlis japonicus oil, fatty acids composition and the content of EPA DHA in the oil. For the dry-abstracted oil at 15℃ under four special temperatures, the oil abstract proportion improves with the increase of solvent concentration; at the same solvent concentration, it decreases with decrease of the abstract proportion temperature. For C\-(14) fatty acids and C\-(16)C\-(18) saturated fatty acids, the organic solvent abstract remove result is remarkable, but for C\-(20)C\-(22) saturated fatty acids, the result is faint. Under four temperatures, the contents of EPA DHA are as follows: 29.88%,31.74%,35.27%,41.80% respectively. It is higher than American ALASKA oil (28.76%)to 1.12%～13.04%.
