Abstract

Processes for the simultaneous production of sterols and polar lipids, in which preparations of vegetable oil lecithin fractions are subjected to ultrafiltration and, on the one hand, the sterols in the permeate and, on the other hand, the polar lipids in the retentate are enriched. The permeate and retentate can subsequently be worked up by methods known per se.
