Animal and vegetable fats and oils - Determination of unsaponifiable matter - Method using hexane extraction

Migrated from Progress Sheet (TC Comment) (2000-07-10): Revision of EN ISO 3596-2 (CC/000705)

Tierische und pflanzliche Fette und Öle - Bestimmung der unverseifbaren Bestandteile - Verfahren mit Hexan-Extraktion

Diese Internationale Norm legt ein Verfahren fest, bei dem die Bestimmung des Gehaltes an unverseifbaren Bestandteilen von tierischen und pflanzlichen Fetten und Ölen mittels dreimaliger Hexan-Extraktion durchgeführt wird.
Dieses Verfahren ist auf alle Fette und Öle, jedoch nicht auf Wachse anwendbar.
WARNUNG  Im Vergleich zu dem in ISO 3596 beschriebenen Verfahren führt das vorliegende Verfahren zu systematisch niedrigen Ergebnissen.

Corps gras d'origines animale et végétale - Détermination de la teneur en matieres insaponifiables - Méthode par extraction a l'hexane

La présente Norme internationale spécifie une méthode à trois extractions à l'hexane pour la détermination de la teneur en matières insaponifiables des corps gras d'origines animale et végétale.  Cette méthode est applicable à tous les corps gras mais pas aux cires.  ATTENTION - Par rapport à la méthode donnée dans l'ISO 3596, la présente méthode donne des résultats systématiquement faibles.
