摘 要：
对鱼粉加工副产物中鱼油的精制进行研究,得到鱼粉加工副产物中鱼油精炼的最佳工艺:添加1%磷酸(体积分数60%)脱胶,3%Na OH(质量分数12%)溶液脱酸以及15%活性炭脱色,在85℃条件下减压蒸馏脱臭10 min。在精炼过程中,鱼油中饱和脂肪酸含量下降,其他脂肪酸含量变化较小。所制备鱼油的理化指标均达到精制鱼油一级要求,其中多不饱和脂肪酸总含量达到0.69 g/m L,二十二碳六烯酸和二十碳五烯酸含量分别为0.229 g/m L和0.121 g/m L。

摘 要：
The refinement of fish oil from byproducts of fish meal processing was researched in this study. The optimal processing parameters for fish oil refinement were determined as follows: after adding 1% of 60% phosphoric acid for degumming, 3% of 12% Na OH for deacidification, and 15% of active carbon for decolorization, vacuum distillation 85 ℃ for 10 min for deodorization. After the refinement the amount of saturated fatty acids dropped, and other fatty acids were little changed; the total amount of polyunsaturated fatty acids(PUFA) was 0.69 g/m L and the contents of docosahexenoic acid(DHA) and eicosapentaenoic acid(EPA) were 0.229 g/m L and 0.121 g/m L, respectively. Physicochemical indexes of the refined oil accorded with quality requirements for first-grade refined fish oil.
