鱼粉压榨液中二十碳五烯酸和二十二碳六烯酸的富集及其甘油酯化OA北大核心CSTPCD
Enrichment and glyceride synthesis of eicosapentaenoic acid and docosahexaenoic from pressed liquor of fish meal processing
该文从鱼粉压榨液中富集二十碳五烯酸(eicosapentaenoic acid,EPA)和二十二碳六烯酸(docosahexaeno-ic acid,DHA),进而采用固定化酶CALB-A两步法催化合成甘油酯型鱼油.结果表明,经一级分子蒸馏富集的乙酯型鱼油中EPA+DHA含量为43.2％,回收率为87.04％;以固定化酶CALB-A催化该乙酯型鱼油和甘油反应合成甘油酯型鱼油,优化后的条件为,以甘油/乙酯物质的量比1∶4、2％加酶量(以底物总质量计…查看全部>>
Eicosapentaenoic acid(EPA)and docosahexaenoic acid(DHA)were enriched from pressed liquor of fish meal process-ing,and then glyceride was synthesized by immobilized enzyme CALB-A in two steps.Results showed that the total content of EPA and DHA in ethyl ester fish oil enriched by first-order molecular distillation was 43.2％,and the recovery rate was 87.04％.The esterification of ethyl ester fish oil with glycerol was catalyzed by the immobilized enzyme CALB-A …查看全部>>
