摘要
采用正交实验,对梭子蟹下脚料中蟹油的溶剂法提取工艺进行了研究,同时分析测定了蟹油的理化特性和脂肪酸组成。结果表明,无水乙醇为提取蟹油的理想溶剂,其最优提取条件为:温度75℃、时间60min、液料比5∶1;经过精炼,蟹油各项理化指标均达到鱼油SC/T3502-2000标准的精制鱼油一级要求;精制蟹油中饱和脂肪酸(SFA)含量为41.79%,不饱和脂肪酸(MUFA)含量为56.94%,其中EPA和DHA含量分别为10.50%和1.03%,蟹油是一种很好的保健油脂,具有很高的开发前景。
The solvent extraction of crab oil in swimming crab waste was performed by orthogonal trials, and the physicochemical properties and fatty acid composition of crab oil were analyzed. The results showed that anhydrous ethanol was the best extraction solvent for crab oil, and the optimal conditions were as follows. temperature 75~C,time 60min,ratio of solvent to material 5：1 ;The physical and chemical indexes of refined crab oil accorded with the first refined fish oil demand for SC/T3502-2000 standard;The content of SFA was 41.79%, M UFA was 56.94% ,the content of DHA and EPA was 10.50% and 1.03%, respectively.The crab oil is a sanitarian seafood oils ,has high developing potentiality.
