Animal and vegetable fats and oils - Determination of tocopherol and tocotrienol contents by high-performance liquid chromatography (ISO 9936:2006)
This International Standard specifies a method for the determi nation of the contents of free , , , and -tocopherols and tocotrienols (referred to jointly as tocols) in animal and vege table fats and oils (referred to hereinafter as fats) by high- performance liquid chromatography (HPLC). For products contain ing tocopherol or tocotrienol esters, it is necessary to carry out a preliminary saponification.
Tierische und pflanzliche Fette und Öle - Bestimmung des Tocopherol- und Tocotrienol-Gehaltes mit Hochleistungsflüssigchromatographie (ISO 9936:2006)
Diese Internationale Norm legt ein Verfahren zur Bestimmung des Gehalts an freien a-, b-, g- und d Tocopherolen und Tocotrienolen (nachfolgend insgesamt als Tocole bezeichnet) in tierischen und pflanzlichen Fetten und Ölen (nachfolgend als Fette bezeichnet) durch Hochleistungsflüssigchromatographie (HPLC) fest.
Bei Produkten, die Ester von Tocopherolen oder Tocotrienolen enthalten, ist es erforderlich, eine vorausgehende Verseifung durchzuführen.
ANMERKUNG Ein geeignetes Verfahren mit einer Kaltverseifung wird in Anhang B nur zur Information beschrieben.
Corps gras d'origines animale et végétale - Détermination des teneurs en tocophérols et en tocotriénols par chromatographie en phase liquide a haute performance (ISO 9936:2006)
L'ISO 9936:2006 spécifie une méthode pour la détermination des teneurs en alpha-, bêta-, gamma- et delta-tocophérols et tocotriénols libres des graisses et des huiles d'origines animale et végétale, par chromatographie en phase liquide haute performance (CLHP).
Pour les produits contenant des esters de tocophérols ou de tocotriénols, il est nécessaire qu'ils subissent une saponification préalable.
