Animal and vegetable fats and oils - Determination of acid value and acidity (ISO 660:2020)
This document specifies three methods (two titrimetric and one potentiometric) for the determination
of acidity in animal and vegetable fats and oils, hereinafter referred to as “fats”. The acidity is expressed
preferably as acid value or, alternatively, as acidity calculated conventionally.
This document is applicable to refined and crude vegetable or animal fats and oils, soap stock fatty
acids or technical fatty acids. It does not apply to waxes.
Since the methods are completely non-specific, they do not apply to differentiating between mineral
acids, free fatty acids and other organic acids. The acid value, therefore, includes any mineral acids that
are present.
Milk and milk products (or fat coming from milk and milk products) are excluded from the Scope of this
document.
Tierische und pflanzliche Fette und Öle - Bestimmung der Säurezahl und der Azidität (ISO 660:2020)
Dieses Dokument legt drei Verfahren (zwei titrimetrische und ein potentiometrisches) zur Bestimmung der Azidität in tierischen und pflanzlichen Fetten und Ölen, die im Folgenden als „Fette“ bezeichnet werden, fest. Die Azidität wird vorzugsweise als Säurezahl ausgedrückt oder alternativ als konventionell berechnete Azidität.
Dieses Dokument gilt für raffinierte und rohe pflanzliche oder tierische Fette und Öle, Soapstock-Fettsäuren oder technische Fettsäuren. Es gilt nicht für Wachse.
Da die Verfahren vollkommen unspezifisch sind, gelten sie nicht zur Unterscheidung zwischen Mineralsäuren, freien Fettsäuren und sonstigen organischen Säuren. Die Säurezahl schließt daher alle vorhandenen Mineralsäuren ein.
Milch und Milcherzeugnisse (oder Fett aus Milch und Milcherzeugnissen) sind vom Anwendungsbereich dieses Dokumentes ausgenommen.
Corps gras d'origines animale et végétale - Détermination de l'indice d'acide et de l'acidité (ISO 660:2020)
Le présent document spécifie trois méthodes (deux titrimétriques et une potentiométrique) pour la détermination de l'acidité dans les corps gras d'origines animale et végétale dits «corps gras». L'acidité est exprimée, de préférence, en indice d'acide ou bien en acidité calculée conventionnellement.
Le présent document est applicable aux corps gras d'origines végétale ou animale à l'état brut ou raffinés, aux acides gras des pâtes de neutralisation ou aux acides gras de qualité technique. Il ne s'applique pas aux cires.
Ces méthodes ne sont en aucun cas spécifiques, elles ne s'appliquent donc pas à la différenciation des acides minéraux, acides gras libres et autres acides organiques. De ce fait, l'indice d'acide inclut tout acide minéral présent.
Le lait et les produits laitiers (ou la matière grasse issue du lait et des produits laitiers) sont exclus du domaine d'application du présent document.
