DEFINITION This method is for the determination of polymerized triglyceride content in oils and fats. The separation is based on the relative retention of solubilized polymer molecules in terms of their molecular size by gel-permeation chromatography. SCOPE This method is applicable to vegetable and animal fats and oils, heated or not. It has been applied to the determination of polymers in animal feed fats and used frying fats or oils at levels >3%. Not suitable for test samples containing Olean.
