Process for the continuous fractionation of a mixture of fatty acids

Abstract From the Canadian patent

To enrich a fat of animal or vegetable origin containing biologically active polyunsaturated fatty acids with such acids, an inclusion complex of the fatty acids is formed with a complexing agent in solution and the solution is cooled by passage through a line of one to five scraped-surface heat exchangers, after which an enriched fraction is collected in the liquid phase. The enriched fractions optionally recombined with, glycerol and brought into a form suitable for their application, may constitute nutritive, cosmetic dermato-, logical or pharmaceutical products or may even be used as starting material for the synthesis of dihomo-.gamma.-linolenic acid.
