Abstract
Abstract We present chemometric study to identify the provenance of agricultural product, beef. Combination of instrumental neutron activation analysis (INAA) and prompt gamma-ray analysis (k 0-PGA) were performed to determine 10 elements, C, H, N, S, Sm, Br, Mg, Na, K, Cl, nondestructively. We measured elemental profiles in beef samples produced from different districts in Japan, Australia and USA. In the case of PGA, k 0-method was employed to determine the elemental concentrations. There was a difference in elemental profiles between Japanese black cattle beef and that produced in USA through principal component analysis (PCA). However, Holstein beef of Japan and that of Australia was not sufficiently grouped by the PCA modeling with the elemental data set. This is the first study to identify the provenance of beef through elemental analysis.
