Metabolomic profiling to detect different forms of beef fraud using rapid evaporative ionisation mass spectrometry (REIMS)

Model Builder (AMX) software (v 0.9.2092.0) (Waters Research Centre, Budapest, Hungary). The data was subject to the MassLynx pre-processing and peak picking algorithms, after which it was lockmass corrected to m/z 554.2615 using the Leu-Enk signal contained within each RAW data file, background subtracted and normalised using total ion count (TIC). The recorded scans for each sample were combined to give an average spectrum, resulting in one averaged spectrum for each sample being used in the...
