Kjeldahl Nitrogen Analyzer manufacturers tell you that the universal applicability, accuracy, and repeatability of the Kjeldahl method have been widely recognized internationally. It has been established as the standard method for testing protein content in food.
However, Kjeldahl Nitrogen Analyzer manufacturers tell you that this method does not give the true protein content, as the nitrogen measured may not be derived solely from the protein. For example, melamine, a substance with a higher nitrogen content, is added to foods to fake higher nitrogen levels.
In addition, Kjeldahl Nitrogen Analyzer manufacturers tell you that this method also requires many different correction factors for different amino acid sequences. Moreover, the Kjeldahl method also requires the use of concentrated sulfuric acid and prolonged heating (generally, more than 1 hour). This also makes the Dumas method sometimes more convenient for rough measurements of protein content.
The above information is the Kjeldahl Nitrogen Analyzer manufacturer's introduction and analysis of the characteristics of Kjeldahl Nitrogen Determination, hope it helps you.
