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

摘要

In the method of the invention to obtain lipids with a high proportion of long-chain polyunsaturated fatty acids (LCPs) with 20 to 22 carbon atoms by extraction from a raw material of animal or vegetable origin, unicellular algae (microalgae), macroalgae from the families of the brown, red and green algae and/or residues of alginate or carrageenin production with a water content of ? 50 weight % and a particle size of ? 50 mm are used. For extraction, an organic solvent or a compressed gas is used. A lipid extract with a high proportion of w6 LCP and w3 LCP and in particular with a content of at least S weight % of arachidonic acid and/or a content of at least 3 weight % of docosahexanoic acid is also prepared.
