Foodstuffs - Determination of nitrate and/or nitrite content - Part 3: Spectrometric determination of nitrate and nitrite content of meat products after enzymatic reduction of nitrate to nitrite

This European Prestandard specifies a spectrometric method for the determination of nitrate and nitrite content of meat products and has been validated for a total nitrite and nitrate content of 25 mg/kg as nitrite ion. Note: Experiences have shown that the methods is also applicable for total nitrite and nitrate content for 10 mg/kg up to 50 mg/kg as nitrite ion. For further information on applicability, see (1).

Lebensmittel - Bestimmung des Nitrat- und/oder Nitritgehaltes - Teil 3: Spektralphotometrische Bestimmung des Nitrat- und Nitritgehaltes in Fleischerzeugnissen nach enzymatischer Reduktion von Nitrat zu Nitrit

Diese Europäische Norm legt ein spektralphotometrisches Verfahren zur Bestimmung des Nitrat- und Nitritgehaltes von Fleischerzeugnissen fest und ist für verschiedene Fleischerzeugnisse mit Gehalten von 9 mg/kg bis 22 mg/kg an Nitrit, berechnet als Natriumnitrit, und 23 mg/kg bis 48 mg/kg an Nitrat, berechnet als Natriumnitrat, im Ringversuch geprüft worden.
ANMERKUNG   Erfahrungen haben gezeigt, dass das Verfahren auch auf Gesamtnitrat/-nitritgehalte von 5 mg/kg bis 125 mg/kg (berechnet als Natriumnitrit) angewendet werden kann. Weitere Informationen zur Anwendbarkeit siehe [1].

Produits alimentaires - Détermination de la teneur en nitrates et/ou en nitrites - Partie 3 : Détermination spectrométrique de la teneur en nitrates et en nitrites des produits carnés après réduction enzymatique des nitrates en nitrites

Cette Norme européenne spécifie une méthode de détermination spectrométrique de la teneur en nitrates et en nitrites dans les produits carnés, et a été validée pour différents produits carnés pour une teneur en nitrites comprise entre 9 mg/kg et 22 mg/kg, exprimée en nitrite de sodium et une teneur en nitrates comprise entre 23 mg/kg et 48 mg/kg, exprimée en nitrate de sodium.
NOTE   Des expériences ont montré que cette méthode est aussi applicable pour une teneur totale en nitrites et en nitrates allant de 5 mg/kg à 125 mg/kg, exprimée en nitrite de sodium. Pour de plus amples informations sur son applicabilité, se reporter au [1].
