Analytical services are offered to support projects carried out at the Wisconsin Center for Dairy Research. The analytical support group provides comprehensive chemical and microbiological testing services and follows EURACHEM-CITAC Guide CG-2 as QA guideline of non-routine and R&D analysis of samples. Tests performed include:

• Crude protein
• Casein
• True protein
• Milkfat
• Total solids and mineral content by reference methods
• Enzymatic determination of lactose and galactose
• Protein profiles of milk and milk products by capillary electrophoresis and cheese proteolysis are determined routinely
• CDR has capabilities to determine particle size analysis and fatty acid composition by gas chromatography and the oxidative stability of oils and fats
• Rheological tests performed include texture profiles, cheese meltability and functional properties of milk products
• Microbiological dairy food safety and quality tests are routinely determined, including tests for coliforms, standard plate count, plus yeast and mold
• Shelf life and microbial challenge studies are also performed
