A method for extracting sphinogomyelin from a phospholipid- containing fat concentrate is described. The method comprises the following steps: A) dissolving the fat concentrate in a solvent mixture of an essentially polar organic solvent and an essentially non-polar organic solvent, B) withdrawing a phase consisting mainly of the non-polar organic solvent and phospholipids dissolved therein, C) adding to the phase withdrawn in step B and organic solvent of intermediate polarity at a temperature of about 13-25 °C, thereby forming a precipitate comprising mainly sphingomyelin, together with a viscous phase and a solvent phase, and then, D) withdrawing the precipitate and the viscous phase, and separating them from one another.
