How sample preparation affects protein determination
19 Oct 2026This application note examines how grinding conditions influence the accuracy and reproducibility of nitrogen and protein analysis in food and feed samples. Discover how insufficient homogenization, excessive grinding, and moisture loss can alter measured protein values and increase analytical variability. Explore comparative results across sunflower seeds, wheat, nut mixes and meat, demonstrating the importance of optimizing sample preparation for each matrix. The study highlights how combining protein analysis with moisture determination helps ensure representative, reliable, and analytically valid results.
