WebHere, we have used 1 H-NMR spectroscopy along with MvDA to differentiate various meat types. The spectral data acquired from NMR provided useful information, and a total of 37 metabolites were identified in chicken, chevon, beef and donkey meat. In MvDA, models developed were successfully validated and were able to discriminate all the meat groups.
