Abstract / scope

ISO/TS 16634-2:2009 specifies a method for the determination of the total nitrogen content and the calculation of the crude protein content of cereals, pulses and milled cereal products.

This method, like the Kjeldahl method, does not distinguish between protein nitrogen and non-protein nitrogen. For the calculation of the protein content, various conversion factors, given in the document, are used.
