Cereals and pulses - Determination of the nitrogen content and calculation of the crude protein content - Kjeldahl method (ISO 20483:2006); German version EN ISO 20483:2006

DIN EN ISO 20483-2007 发布历史

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 can be applied. NOTE In certain cases, full recovery of the nitrogen in nitrates and nitrites is not possible by this method.
