Food products - Determination of the total nitrogen content by combustion according to the Dumas principle and calculation of the crude protein content - Part 1: Oilseeds and animal feeding stuffs (ISO 16634-1:2008)

ISO 16634-1:2008 specifies a method for the determination of the total nitrogen content and the calculation of crude protein content of oilseeds and animal feeding stuffs.
This method, like the Kjeldahl method, does not distinguish between protein nitrogen and non-protein nitrogen. For the calculation of protein content, various conversion factors are used.
This method is not applicable to milk and milk products.

Lebensmittelerzeugnisse - Bestimmung des Gehaltes an Gesamtstickstoff mit dem Verbrennungsverfahren nach Dumas und Berechnung des Gehaltes an Rohprotein - Teil 1: Ölsaatenschrote und Futtermittel (ISO 16634-1:2008)

Dieser Teil von ISO 16634 legt ein Verfahren zur Bestimmung des Gesamtstickstoffgehaltes und zur Berechnung des Rohproteingehaltes von Ölsaatenschroten und Futtermitteln fest.
Dieses dem Kjeldahl-Verfahren ähnliche Verfahren unterscheidet nicht zwischen Protein Stickstoff und Nicht Protein Stickstoff. Zur Berechnung des Proteingehaltes werden verschiedene Umrechnungsfaktoren verwendet (siehe Anhang D).
Dieses Verfahren gilt nicht für Milch und Milcherzeugnisse, für welche ein Verfahren in der ISO 14891IDF 185 [10] festgelegt ist.

Produits alimentaires - Détermination de la teneur en azote total par combustion selon le principe Dumas et calcul de la teneur en protéines brutes - Partie 1: Graines oléagineuses et aliments des animaux (ISO 16634-1:2008)

L'ISO 16634-1:2008 spécifie une méthode pour la détermination de la teneur en azote total et le calcul de la teneur en protéines brutes des graines oléagineuses et des aliments pour animaux.
Cette méthode, comme la méthode Kjeldahl, ne distingue pas l'azote protéique de l'azote non protéique. Divers facteurs de conversion sont utilisés pour le calcul de la teneur en protéines.
Cette méthode ne s'applique pas au lait et aux produits laitier.
