Abstract

A triglyceride oil containing a membrane lipid in a concentration effective for crystallization modification the membrane lipid having a formula: EQU C.sub.13 H.sub.27 --CH.dbd.CH--CH(OH)--CH(NHCOA.sub.2)--CH2--OA.sub.4, wherein C.sub.13 H.sub.27 -- is an unbranched alkyl chain, A.sub.2 is an unbranched C.sub.23 H.sub.47 -- hydrocarbon chain, and A.sub.4 is a sugar moiety selected from the group consisting o a monosaccharide residue, a disaccharide residue or an oligosaccharide residue, including glucose, fructose, galactose, saccharose, lactose and maltose. Said membrane is utilized to separate solid fatty materials from triglyceride oils by heating the oil in an inert solvent until a substantial amount of the solid material is no longer present, adding the membrane lipid as the crystallization modifying substance, cooling the oil to crystallize a solid stearin phase in combination with a liquid olein phase, and recovering the stearin phase by separating it from the olein phase.
