1. A process for the purification of a crude glyceride oil composition which comprises diluting the crude glyceride oil composition containing a glyceride oil and phospholipid with an organic solvent, bringing the diluted crude glyceride oil composition under pressure into contact with an internal pressure capillary semipermeable membrane having an inner diameter of 0.1 to 2 mm to separate it into a semipermeable membrane permeable liquid and a semipermeable membrane impermeable liquid, bringing the thus-concentrated semipermeable membrane impermeable liquid under pressure into contact with an internal pressure type tubular semipermeable membrane having an inner diameter which is greater than that of the above capillary semipermeable membrane and which is 20 mm or less to separate it into a semipermeable membrane permeable liquid and a semipermeable membrane impermeable liquid, and removing the organic solvent from at least one of the total semipermeable membrane permeable liquid and the semipermeable membrane impermeable liquid to obtain a purified glyceride oil and/or a purified phospholipid.
