A micro method for the determination of protein and screening of added water in meat and meat products

  • Published:
Microchimica Acta Aims and scope Submit manuscript

Summary

The automatic Dumas method is feasible for determining the protein and screening for added water in meats and meat products. It is rapid, convenient, and requires less laboratory space and cost for routine operation. Homogeniety of the meat sample is important. Samples identified as positive for added water should be confirmed and quantified by the official macro-Kjeldahl method.

Zusammenfassung

Die automatisierte Dumas-Methode eignet sich für die Proteinbestimmung in Fleisch und Fleischwaren zwecks Ermittlung von Wasserzusätzen. Das Verfahren ist rasch durchzuführen, beansprucht wenig Platz im Labor und verursacht im Routinebetrieb nur geringe Kosten. Die Fleischproben müssen homogen sein. Gegebenenfalls festgestellter Wasserzusatz soll mit der offiziellen Makro-Kjeldahlmethode verifiziert werden.
