multipe reaction mass spectrometry (1)

IFR has developed a rapid multiple reaction monitoring mass spectrometry method for the detection and relative quantitation of the adulteration of meat with that of an undeclared species is presented. Selected peptide markers derived from myoglobin can be used for species detection, and the ratios of  transition peak areas for corresponding peptides is proposed for relative quantitation. The method has been developed from the myoglobin of four meat species - beef, pork, horse and lamb, and test results are encouraging.
