The present invention relates to a counter-current extraction process involving a plurality of mixing and separation stages for fractionating a phospholipid-containing feed material into two or more fractions enriched in one or more phospholipids, comprising (a) contacting the phospholipid-containing starting material under agitation with an extractant comprising an aliphatic alcohol selected from C1 to C3 alcohols; (b) separating the obtained emulsion into a phospholipid-enriched extract from a residual raffinate.
