Abstract: | It has become necessary to assess the authenticity of beef origin because of concerns regarding human health hazards. In this
study, we used a metabolomic approach involving matrix-assisted laser desorption/ionization imaging mass spectrometry to assess
the authenticity of beef origin. Highly accurate data were obtained for samples of extracted lipids from beef of different
origin; the samples were grouped according to their origin. The analysis of extracted lipids in this study ended within 10 min,
suggesting this approach can be used as a simple authenticity assessment before a definitive identification by isotope analysis. |
