Protein Determination after DUMAS in Milk and Milk Products

March 21, 2024

Perfect and easy analysis for solid and liquid products.

Protein is one of the most significant nutrient components in milk products. The accurate and precise determination of protein not only plays a role in the characterization of nutritional or dietary value of milk products but is also the key to determining the economic value of these materials. Protein in milk products is most commonly calculated using the measured total nitrogen content in the sample and a multiplier or conversion factor (typically 6.38). Nitrogen determination is performed using either the classical wet chemical method (Kjeldahl), or a combustion method (Dumas).
