Cereals and pulses - Determination of the nitrogen content and calculation of the crude protein content - Kjeldahl method (ISO 20483:2013)

ISO 20483:2013 specifies a method for the determination of the nitrogen content of cereals, pulses and derived products, according to the Kjeldahl method, and a method for calculating the crude protein content. The method does not distinguish between protein nitrogen and non-protein nitrogen.

Getreide und Hülsenfrüchte - Bestimmung des Stickstoffgehaltes und Berechnung des Rohproteingehaltes - Kjeldahl-Verfahren (ISO 20483:2013)

Diese Internationale Norm legt ein Verfahren zur Bestimmung des Stickstoffgehaltes von Getreide, Hülsen-früchten und deren Produkten nach dem Kjeldahl-Verfahren und ein Verfahren zur Berechnung des Rohproteingehaltes fest.
Das Verfahren unterscheidet nicht zwischen Proteinstickstoff und Nichtproteinstickstoff. Wenn es wichtig ist, den Gehalt an Nichtproteinstickstoff zu bestimmen, würde ein geeignetes Verfahren hierzu angewendet werden.
ANMERKUNG   In bestimmten Fällen ist eine vollständige Erfassung des in Nitraten und Nitriten vorliegenden Stickstoffs mit diesem Verfahren nicht möglich.

Céréales et légumineuses - Détermination de la teneur en azote et calcul de la teneur en protéines brutes - Méthode de Kjeldahl (ISO 20483:2013)

L'ISO 20483:2013 spécifie une méthode pour la détermination de la teneur en azote des céréales, des légumineuses et des produits dérivés, selon la méthode de Kjeldahl, ainsi qu'une méthode de calcul de la teneur en protéines brutes. La méthode ne fait pas la distinction entre l'azote protéique et l'azote non protéique.
