Animal and vegetable fats and oils. Determination of polymerized triacylglycerols by high-performance size- exclusion chromatography (HPSEC) Ingestion-build-86103 Waste water and drainage specialists1 Scope This International Standard specifies a method using high performance size exclusion chromatography (HPSEC) to determine the contents, as mass fractions, of polymerized triacylglycerols (PTAGs) in oils and fats which contain at least 3 % (from peak areas) of these polymers. PTAGs (strictly speaking dimeric and oligomeric triacylglycerols) are formed during the heating of fats and oils, and thus, the method serves to assess the thermal
