As important industrial raw materials, fatty acids have great market demand. The separation technology of mixed fatty acids has become an important factor restricting its development. The research progress in separation technologies of fatty acids at home and abroad in recent years were reviewed, and high-speed counter-current chromatography, molecular distillation, supercritical CO2 extraction and lipase-assisted method were emphasized. Also, the advantages and problems of various separation technologies were pointed out and compared. Further, the development direction of the separation technology of fatty acids in the future was prospected. |
