The determination of the total protein content is an essential tool for quality control and protein declaration according to international labeling laws in the food & feed industry and research facilities. Protein content can directly correspond to product properties and classifications e.g. dough properties, foam formation, the taste of beer, or the differentiation between starch and gluten-free starch. In all application areas highly precise, matrix-independent protein analyses are required.
In comparison to Kjeldahl analysis, N/Protein analysis by Dumas, high-temperature combustion is faster, more cost-effective, less labor-intensive, and doesn’t require the use of toxic chemicals. A major expense of traditional Dumas combustion is the reduction metals needed to bind excess oxygen and convert nitrogen oxides to molecular nitrogen. With Elementar’s patent-pending EAS REGAINER®
and EAS REDUCTOR®
technology, this cost has been greatly reduced, further driving the advantage of these Dumas analyzers over comparable systems.
