Cereals and pulses - Determination of the nitrogen content and calculation of the crude protein content - Kjeldahl method - Second Edition
N 20483
Annotation
This International Standard 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. If it is important to determine the non-protein nitrogen content, an appropriate method would be applied.
NOTE In certain cases, full recovery of the nitrogen in nitrates and nitrites is not possible by this method.
Автоматический перевод:
Крупы и бобы - Определение содержания азота и вычисление содержания сырого белка - Метода Кьельдаля - Второй Выпуск
Этот Международный стандарт определяет метод для определения содержания азота круп, бобов и полученных продуктов, согласно Методу Кьельдаля и методу для вычисления содержания сырого белка.
Метод не различает белковый азот и небелковый азот. Если бы важно определить содержание небелкового азота, надлежащий метод был бы применен.
