If it is necessary to determine the amount of protein in a mixture of animal foodstuffs, a sample is converted to ammonium salts by boiling with sulfuric acid and a suitable inorganic catalyst, such as copper sulfate (Kjeldahl method). The method is based on the assumption that proteins ...
for modifying NPN extraction. Due to an increase in the production of ingredients from membrane separation processes, it is prudent to have a different protocol for NCN and NPN protein estimation by Kjeldhal analysis. Based on the results, to achieve targeted 80% CP/TS ratio, we recommend an...
