Claim:
1. A counter-current extraction process involving a plurality of mixing and separation stages for fractionating a phospholipid-containing starting material into two or more fractions enriched in one or more phospholipids, comprising the following steps: (a) contacting the phospholipid-containing starting material under agitation with an extractant comprising an aliphatic alcohol selected from C (b) separating the obtained mixture into a phospholipid-enriched extract from a residual raffinate by a process comprising applying centrifugal forces, wherein the phospholipid-enriched extract from each separation stage is at least in part returned to a previous, or further upstream mixing stage, and wherein a final phospholipid-enriched extract is separated from a first residual raffinate, and wherein a final raffinate phase is obtained having between 55 and 75 wt % of Acetone Insolubles (AI).
