ABSTRACT:
The invention relates to a process for quantitatively purifying glycolipids, wherein the purification of the glycolipids is effected by acidifying the glycolipid-containing solution to pH .ltoreq.5.0, then heating the batch to 60.degree. C.-130.degree. C., and then cooling the batch down to .ltoreq.50.degree. C. and centrifuging it at .gtoreq.500 g in order to sediment the glycolipid-containing phase.
