Determination of Nitrogen/Protein in Whey Products on FP628

Whey protein is a common ingredient in many dietary supplements due to its availability, solubility, and unique functional characteristics. The accurate and precise determination of protein in whey products not only plays a role in the characterization of nutritional or dietary value in dairy products, but may also be a key in determining the quality or category of the whey product. Protein in whey and other food products is most commonly calculated using the measured nitrogen in the sample and a protein factor multiplier (protein factors vary according to the sample matrix).Learn more...
