Determination of Nitrogen/Protein in Whey and Powdered Dairy Products

Whey protein, a water-soluble co-product of cheese production, is a vital ingredient in dietary supplements and various dairy-based goods. Accurately determining protein content is essential for characterizing the nutritional value of these products and ensuring they meet specific quality categories. Utilizing the Dumas combustion method, the FP928 macro nitrogen/protein determinator handles large sample masses in a high-temperature horizontal furnace. By applying a matrix-specific protein factor to the measured nitrogen, producers can achieve the high-precision results necessary for reliable product labeling and quality control.
