PROCESS FOR EXTRACTING LIPIDS WITH A HIGH PROPORTION OF LONG CHAIN, HIGHLY UNSATURATED FATTY ACIDS

摘要

The invention relates to a process for extracting high-grade lipid in highly unsaturated fatty acids to long chain (LCP) having 20 to 22 carbon atoms, from a raw material of animal or vegetable origin. Is used as raw material monocellular algae (microalgae), macroalgae of the families of brown algae, red and green and / or residues from alginate or carrageenan extraction with a water content of 50% by weight and grain size 50 mm. For extraction, using an organic solvent or a condensed gas. Is also obtained a lipid extract with high content of w6-LCP and LCP-w3 and containing in particular at least 5% by weight arachidonic acid and / or at least 3% by weight of docosahexaenoic acid.
