In the second part of this blog series, we will detail a comparison test for determining non-protein nitrogen (NPN) and non-casein nitrogen (NCN).
We are introducing a short series of blog posts to explore the benefits of the Dumas method of protein determination with a focus on milk and milk products.
Unlike the Kjeldahl method, the Dumas method avoids toxic acids, making it safer for the environment and health. It is also simpler, faster, and more sustainable. Many food labs now prefer or supplement the Kjeldahl method with the Dumas method for protein determination in food and feed.
