Abstract
A mixture of fatty acids, including derivatives thereof, containing polyunsaturated fatty acids, including derivatives thereof, are fractionated by reacting the mixture with urea in solution for forming a reaction medium which then is pumped at least through one scraped-surface heat exchanger for cooling the reaction medium for forming a dispersion of a solid inclusion complex and a liquid phase. The liquid phase then is separated from the inclusion complex for obtaining a fraction enriched with polyunsaturated fatty acids, including derivatives thereof.
