ISO 16634: Food products — Determination of the total nitrogen content by the Dumas method or Kjeldahl method

ISO 16634 is a standard that specifies methods for determining the total nitrogen content in food products using either the Dumas method or the Kjeldahl method. These methods are used to estimate the protein content in food, which is essential for nutritional labeling, food safety, and regulatory compliance. By following ISO 16634, laboratories can obtain accurate, standardized protein content measurements in food products.
