Influence of sample preparation on C/N/protein values in food and feed analysis

This whitepaper examines how sample preparation directly impacts the accuracy of carbon, nitrogen, and protein analysis in food and feed testing. Discover how insufficient, excessive or prolonged grinding can affect sample homogeneity, moisture content and measured protein values, leading to misleading analytical results. Explore findings from comparative studies on grains, seeds, nuts and meat, and best practices for optimizing grinding conditions, monitoring moisture content and combining elemental and thermogravimetric analysis to ensure reliable, reproducible protein determination.
