How to determine nitrogen and protein with the Dumas and Kjeldahl methods: The case of nitrogen fractions in milk
08 Jul 2021

Many decision makers and laboratory operators are undecided between the Dumas or the Kjeldahl technique for N/Protein determination. These specialized techniques are the primary methods used for nitrogen and protein determination, but can differ in many aspects, including their speed and safety.

In this masterclass, join specialists from VELP Scientifica to learn about the methods, analytical procedures, and results for nitrogen and protein determination. Key evidence will be revealed by presenting the analysis of non-casein nitrogen (NCN) and non-protein nitrogen (NPN) fractions in milk with the Dumas and Kjeldahl methods.

The case of nitrogen fractions in milk will unveil unique characteristics, advantages, and differences associated with these two techniques. After an analytical overview, results will be discussed, and the main steps of a combustion analysis will be presented, alongside a dedicated lab demo.

Key learning objectives:

  • Chemistry of N/Protein determination
  • Kjeldahl method and analytical procedures
  • Dumas method and analytical procedures
  • N/Protein and nitrogen fractions in milk discussion
  • Lab demo: Focus on Dumas
