適用范圍：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 fatswhich contain at least 3 % (from peak areas) of these polymers. PTAGs (strictly speaking dimeric andoligomeric triacylglycerols) are formed during the heating of fats and oils, and thus, the method serves toassess the thermal deterioration of frying fats after use.This method is applicable to frying fats and fats and oils that have been thermally treated, provided that thecontent of PTAGs is at least 3 %. It can also be applied to the determination of polymers in fats for animalfeedstuffs, although in this case, the extraction method used can have an influence on the result.NOTE For further details, see ISO 6492.
