摘要

超临界流体越来越多地被用作传统有机溶剂的替代品，用于从一系列基质中提取生物分子。研究了超临界流体萃取鱼油中必需脂肪酸的工艺。用超临界CO2从鱼油乙酯中分离出EPA和DHA两种脂肪酸。以原始成分为17%和12%的沙丁鱼油为原料，分别以58%和67%的纯度获得EPA和DHA。

Separation of biomolecules using supercritical fluid extraction.

Supercritical fluids are increasingly being used as a replacement for more conventional organic solvents in the extraction of biomolecules from a range of matrices. Supercritical fluid extraction of essential fatty acids from fish oils is discussed. Supercritical CO2 was used to fractionate two fatty acids, EPA and DHA from fish oil ethyl esters. EPA and DHA were obtained with a purity of 58% and 67% respectively from Sardine oil with an original composition of 17% and 12%.
