Separation of EPA and DHA from fish oil fatty acid ethyl ester (FAFE) by urea adductive crystallization method was carried out in the supercritical carbon dioxide (SC CO₂) as a solvent. Our results showed that SC CO₂is a good candidate as a solvent in the adductive crystallization to separate FAFF by the number of unsaturated bohds. Compared to the separation process using methanol, SC CO₂yielded better performance in the overall selectivity of EPA and DHA. The effect of process variables on separation of EPA and DHA was discussed in detailed. A hybrid technology of SC CO₂fractionation and urea adductive crystallization with SC CO₂was conformed as a viable process to separate and concentrate EPA and DHA from fish oil.
