DESCRIPTION
BS EN ISO 16634-2:2016
This standard BS EN ISO 16634-2:2016 Food products. Determination of the total nitrogen content by combustion according to the Dumas principle and calculation of the crude protein content is classified in these ICS categories:
- 67.050 General methods of tests and analysis for food products
- 67.060 Cereals, pulses and derived products
This part of ISO 16634 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 (see References [1] and [6]), does not distinguish between protein nitrogen and non-protein nitrogen. For the calculation of the protein content, various conversion factors are used (see 3.2).
