Animal and vegetable fats and oils — Determination of polymerized triacylglycerols by high-performance size-exclusion chromatography (HPSEC) - Second Edition
N 16931
Annotation
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 deterioration of frying fats after use.
This method is applicable to frying fats and fats and oils that have been thermally treated, provided that the content of PTAGs is at least 3 %. It can also be applied to the determination of polymers in fats for animal feedstuffs, although in this case, the extraction method used can have an influence on the result.
NOTE For further details, see ISO 6492[4].

Животное и растительные жиры и масла — Определение полимеризировавшего triacylglycerols высокоэффективной хроматографией исключения размера (HPSEC) - Второй Выпуск
Этот Международный стандарт определяет метод с помощью высокоэффективной хроматографии исключения размера (HPSEC) для определения содержания, поскольку масса фракционируется полимеризировавшего triacylglycerols (PTAGs) в маслах и жирах, содержащих по крайней мере 3% (из пиковых областей) этих полимеров. PTAGs (строго говоря димерный и oligomeric triacylglycerols) сформированы во время нагревания жиров и масел, и таким образом, метод подает для оценки теплового ухудшения жиров для жарения после использования.
