Faster, safer, more efficient: How dairy laboratories are optimizing their protein analysis

Accurately determining protein and nitrogen content is crucial for quality assurance, product development, and compliance in dairy laboratories. Which method stands out as efficiency, safety, and sustainability requirements continue to rise?

This white paper provides well-founded answers. It compares the established Kjeldahl method with the modern Dumas combustion method in a practical, data-driven manner. The focus is on an independent study commissioned by CNIEL and conducted by ACTALIA Cecalait, which analyzed approximately 350 milk and dairy product samples. The result? A very high degree of agreement between the two methods, with significantly shorter analysis times and higher sample throughput using Dumas technology. Additionally, laboratories benefit from greater safety, reduced manual effort, and the elimination of hazardous chemicals. The Dumas method also shows potential for determining non-protein nitrogen.

The white paper provides a valuable resource for dairy laboratories aiming to modernize their protein analysis and ensure the long-term viability of their operations.
