鲶鱼下脚料中鱼油的提取及贮藏稳定性研究
Extraction and Storage Stability of Fish Oil from Catfish Leftover
摘要
Abstract
To extract fish oil from catfish leftover,experiments were conducted with organic solvents such as acetone, butanol,hexane-isopropryl and so on. The result of the experiments showed that the best extraction method was with hexane-isopropryl. The volume rate of hexane-isopropryl in the first extraction was 3∶2,and in the second time 7∶2;the first ex-traction time was 20 min,the extraction rate was 27.92% and the extracted oil has better organoleptic quality. The stability of the fish oil was best when stored in0-4,℃or in room temperature after adding VE 100,mg/kg. This fish oil contented 65.84% unsaturated fatty acid and 19.96%essential fatty acid,so it is valuable for human healthy.关键词
