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.<\/p>\n

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.<\/p>\n

\n

NOTE In certain cases, full recovery of the nitrogen in nitrates and nitrites is not possible by this method.<\/p>\n<\/blockquote>\n
