PROCESS FOR SEPARATING LIPID MATERIALS

The present invention relates to processes for separating a feed material into soluble and insoluble components, by contacting a feed material and a solvent and subsequently separating the solvent containing the soluble components from the insoluble components, wherein the feed material comprises one or more of: at least 1% by mass phosphatidyl serine, at least 1% by mass sphingomyelin, at least 0.3 % by mass acylalkylphospholipids and/or plasmalogens, at least 0.5 % by mass aminoethylphosphonate and/or other phosphonolipids, at least 1% by mass cardiolipin, and at least 0.3% by mass gangliosides; and wherein the solvent comprises: supercritical or near-critical CO2, and a co-solvent comprising one or more C1-C3 monohydric alcohols, and water, wherein the co-solvent makes up at least 10% by mass of the CO2, and the water content of the co-solvent is 0 to 40 % by mass. The present invention also relates to processes for separating a feed material into soluble and insoluble components, comprising contacting a feed material and a first solvent and subsequently separating the first solvent containing the first soluble components from the first insoluble components, wherein the feed material comprises one or more of: at least 1 % by mass phosphatidyl serine, at least 1% by mass sphingomyelin, at least 0.3 % by mass acylalkylphospholipids and/or plasmalogens, at least 0.5 % by mass aminoethylphosphonate and/or other phosphonolipids, at least 1% by mass cardiolipin, or at least 0.3% by mass gangliosides; and wherein the first solvent comprises supercritical or near-critical CO2. The process then provides contacting the first insoluble components with a second solvent and subsequently separating the second solvent containing the second soluble components from the second insoluble components, wherein the second solvent comprises supercritical or near- critical CO2, and a co-solvent comprising one or more C1-C3 monohydric alcohols, and water, wherein the co-solvent makes up at least 10% by mass of the CO2, and the water content of the co-solvent is 0 to 40% by mass. La présente invention concerne des procédés servant à séparer une matière de charge en composants solubles et insolubles, en mettant en contact une matière de charge et un solvant et en séparant à la suite de cela le solvant contenant les composants solubles des composants insolubles, ladite matière de charge comprenant un ou plusieurs des composants suivants : au moins 1 % en masse de phosphatidylsérine
