ABSTRACT:
A composition concentrated in ethyl esters of polyunsaturated fatty acids is prepared by mixing a refined oil rich in polyunsaturated fatty acids with ethanol in the presence of a catalyst to obtain an ethanolyzate containing a glycerol phase and fatty acid ethyl ester phase. The fatty acid ethyl ester phase is separated from the glycerol phase and mixed with urea and ethanol to form a mixture, which is cooled to form a liquid phase containing fatty acid ethyl esters and a solid phase containing insoluble inclusion complexes. The liquid phase is separated from the solid phase to obtain a fraction enriched in ethyl esters of polyunsaturated fatty acids.
