While some companies still rely on the traditional Kjeldahl method for protein determination, the Dumas method is rapidly climbing in popularity, thanks to instruments like LECO’s FP928. In a recent article published by B&L MedienGesellschaft’s e-magazine, eFOOD-Lab International, Buddhi Dias of Australian Laboratory Services (ALS) shares how the Dumas method is used in their lab for food safety and quality testing.
Dias holds the title of Chemistry Technical Manager for Food Global at ALS. With a background in analytical chemistry, residue analysis, an M.Sc. in Forensic Science, a B.Sc. in Chemistry, and significant experience working in a lab, his diverse industry experiences have taught him a wealth of knowledge that he brings to his current role of driving excellence and innovation in food testing.
ALS provides expertise in various industries, such as dairy and food manufacturing. Their goal in nutritional analyses is to meet safety and quality standards efficiently. The Dumas method, used by LECO’s FP928 instrument, helps ALS achieve this by analyzing numerous samples quickly and safely.
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. The table below highlights official methods using the Dumas method, indicating its growing importance, use and acceptance.
