Johan Gustav Kjeldahl

Johan Gustav Kjeldahl was a Danish chemist known for developing the Kjeldahl method, a technique used to measure the amount of nitrogen in organic substances. This method is fundamental in agriculture and food science, helping determine protein content in food and feed products. By digesting a sample with acid, then converting nitrogen into a measurable form, the Kjeldahl technique provides accurate data essential for quality control and nutritional analysis. Kjeldahl's work significantly contributed to analytical chemistry and improved understanding of food composition, making him a key figure in scientific industries related to nutrition and agriculture.
