|Abstract:||The purpose of this study is to figure out geographical indication in whole milk powder. Thus, 32 whole milk powder samples labeled as originating in New Zealand, Australia, the Netherlands and the Czech Republic were analyzed. The amounts of Ag, A1, As, Ba, Cd, Cr, Cs, Cu, Fe, Li, Mn, Ni, Pb, Rb, Se, Sr, V and Zn were determined by an inductively coupled plasma-mass spectrometer (ICP-MS). The data obtained was analyzed by principal component analysis (PCA). The results revealed that New Zealand milk samples could be differentiated from Australia and the Netherland milk samples by the amounts of A1, As, Ba, Cs, Fe, and Pb. However, there was a limit of using mineral profiles to distinguish the milk samples of New Zealand and Czech Republic.|
