Establishment of metrological parameters of the method for measuring the protein mass fraction in fish food products by the Kjeldahl method

In laboratory practice, there are many protein quantification methods, and all of them have their own advantages disadvantages. The most common widely used method for the analysis in food products, including fish, is Kjeldahl method. However, current standards measurement methods determination content fish products do not provide use devices that meet modern level technical development, also contain metrological indicators guarantee reliability results obtained. aim study was to substantiate measuring mass fraction by on an automatic analyzer establish parameters. assessment quality carried out using a Kjeltec System 2300 Nitrogen Analyzer (Foss Analytical AB, Sweden) form characteristic error its components, which will with required accuracy.
