ABSTRACT:
Countercurrent liquid/liquid extraction processse for fractionating complex triglyceride mixtures to selectively remove "light" impurities (primarily MMM trglycerides) from MML/MLM triglycerides, or to selectively remove MML/MLM triglycerides from "heavy" impurities (primarily MLL/LML and LLL triglycerides), wherein M is a C.sub.6 -C.sub.10 fatty acid residue or mixture thereof, and wherein L is a C.sub.18 -C.sub.24 fatty acid residue or mixture thereof, are disclosed. In the case of "light" impurities, an oil stream containing MMM and MML/MLM triglycerides is passed countercurrently to a solvent stream containing a polar solvent or a supercritical fluid that is partially miscible with the oil stream to selectively remove the MMM triglycerides. In the case of "heavy" impurities, an oil stream containing MML/MLM, MLL/LML and LLL triglycerides is passed countercurrently to the solvent stream to selectively remove the MML/MLM triglycerides.
