Tierische und pflanzliche Fette und Öle - Bestimmung der Peroxidzahl - Potentiometrische Endpunktbestimmung (ISO 27107:2008, korrigierte Fassung 2009-05-15); Deutsche Fassung EN ISO 27107:2010
Overview
This revised International Standard specifies a method for the potentiometric end-point determination of the peroxide value, in milliequivalents of active oxygen per kilogram, of animal and vegetable fats and oils. The method is applicable to all animal and vegetable fats and oils, fatty acids and their mixtures with peroxide values from 0 meq to 30 meq of active oxygen per kilogram. It is also applicable to margarines and fat spreads with varying water content. The method is not applicable to milk fats or lecithins. A method for the iodometric (visual) determination of the peroxide value is given in ISO 3960. For milk fats, a method is specified in ISO 3976.
