Pure phospholipids are recovered from crude phospholipids, for example from soyabean phospholipid slurry, if the crude phospholipids are treated simultaneously with a water-immiscible, nonpolar, phospholipid-dissolving organic liquid and water. When an aqueous crude phospholipid slurry is used, water does not need to be added or only for further dilution. The mixture can contain less than 75% of organic polar solvent. After treatment, the mixture is centrifuged and pure phospholipid is recovered from the hydrophobic phase by evaporation. |
