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 .ltoreq.50 weight % and a particle size of .ltoreq.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 5 weight % of arachidonic acid and/or a content of at least 3 weight % of docosahexanoic acid is also prepared.
A method for obtaining lipids with a high proportion of long-chain polyunsaturated fatty acids (LCPs) having from 20 to 22 carbon atoms by extraction from a raw material of plant origin, characterized in that as the raw material residues from alginate or carrageenan production which have been subjected to drying to provide a water content of .ltoreq.50 weight % and a particle size of .ltoreq.50 mm are used, and that for extraction an organic solvent or a compressed gas is used.
A lipid extract or lipid extract fraction of residues of alginate or carrageenan production, characterized by a content of arachidonic acid of at least 5 weight % and/or a content of docosahexanoic acid of at least 3 weight %, referred to the total weight of the fatty acids.
