PCT No. PCT/SE94/00105 Sec. 371 Date Sep. 21, 1995 Sec. 102(e) Date Sep. 21, 1995 PCT Filed Feb. 10, 1994 PCT Pub. No. WO94/18289 PCT Pub. Date Aug. 18, 1994A method for extracting sphingomyelin from a phospho-lipid-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a phase consisting mainly of the non-polar organic solvent and phospholipids dissolved therein, C. adding to the phase withdrawn in step B an organic solvent of intermediate polarity at a temperature of about 13 DEG -25 DEG C., thereby forming a precipitate comprising mainly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. |
