动植物油脂 用高效尺寸排阻色谱法(HPSEC)测定聚合甘油三酸酯 ISO 16931:2001

Tierische und pflanzliche Fette und ?le. Bestimmung des Gehaltes an polymerisierten Triglyceriden mit Hochleistungs-Ausschlusschromatographie (HPSEC) Animal and vegetable fats and oils. Determination of polymerized triacylglycerols by high-performance size-exclusion chromatography (HPSEC) Corps gras d'origines animale et végétale. Détermination de la teneur en triacylglycérols polymérisés par chromatographie liquide d'exclusion. haute performance (CLHP d'exclusion)

适用范围: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.
