Animal and vegetable fats and oils - Determination of peroxide value - Iodometric (visual) endpoint determination (ISO 3960:2007)
This European Standard specifies a method for the iodometric determination of the peroxide value of animal and vegetable fats and oils with a visual endpoint detection. The peroxide value is a measure of the amount of oxygen chemically bound to an oil or fats as peroxides, particularly hydroperoxides. The method is applicable to all animal and vegetable fats and oil, fatty acids and their mixtures with peroxide values from 0 meq to 30 meq (milliequivalents) of active oxygen per kilogram. It is also applicable to margarines and fat spreads with varying water content. The method is not suitable for milk fats and is not applicable to lecithins. It is to be noted that the peroxide value is a dynamic parameter, whose value is dependent upon the history of the sample. Furthermore, the determination of the peroxide value is a highly empirical procedure and the value obtained depends on the sample mass. It is stressed that, due to the prescribed sample mass, the peroxide value obtained can be slightly lower that those obtained with a lower sample mass.
Tierische und pflanzliche Fette und Öle - Bestimmung der Peroxidzahl - Iodometrische (visuelle) Endpunktbestimmung (ISO 3960:2007)
Die vorliegende Internationale Norm legt ein Verfahren zur iodometrischen Bestimmung der Peroxidzahl von
tierischen und pflanzlichen Fetten und Ölen mit einer visuellen Endpunktbestimmung fest. Die Peroxidzahl ist
ein Maß für die Menge an Sauerstoff, der chemisch in Form von Peroxiden, besonders Hydroperoxiden, an Öl
oder Fette gebunden ist.
Das Verfahren ist auf alle tierischen und pflanzlichen Fette und Öle, Fettsäuren und deren Mischungen mit
Peroxidzahlen von 0 meq bis 30 meq (Milliäquivalente) aktiver Sauerstoff je Kilogramm anwendbar. Es ist
auch anwendbar auf Margarinen und Streichfette mit unterschiedlichem Wassergehalt. Das Verfahren ist nicht
geeignet für Milchfette und ist nicht anwendbar auf Lecithine.
Es ist zu beachten, dass die Peroxidzahl ein dynamischer Parameter ist, dessen Wert von der zeitlichen Veränderung
der Probe abhängt. Außerdem ist die Bestimmung der Peroxidzahl ein stark empirisches Verfahren
und der erhaltenen Wert hängt von der Probenmasse ab. Es ist zu betonen, dass aufgrund der vorgeschriebenen
Probenmasse die erhaltenen Peroxidzahlen geringfügig niedriger sein können als die Peroxidzahlen,
die mit einer geringeren Probenmasse erhalten werden.
ANMERKUNG 1 Ein bevorzugtes Verfahren zur iodometrischen Bestimmung der Peroxidzahl von Milchfetten ist in
ISO 3976 festgelegt.
ANMERKUNG 2 Ein Verfahren zur potentiometrischen Bestimmung der Peroxidzahl ist in ISO 27107 angeführt.
