ICP–MS Analysis of Multi-Elemental Profile of Greek Wines and Their Classification According to Variety, Area and Year of Production

Major, minor and trace elements in wines from Greece were determined by inductively coupled plasma–mass spectrometry (ICP–MS). The concentrations of 44 (Na, Mg, P, K, Ca, Cu, Co, Cr, Zn, Sn, Fe, Mn, Li, Be, B, V, Sr, Ba, Al, Ag, Ni, As, Hg, Pb, Sb, Cd, Ti, Ga, Zr, Nb, Pd, Te, La, Sm, Ho, Tm, Yb, W, Os, Au, Tl, Th, U) 90 white red six different regions for two consecutive vinification years, 2017 2018, determined. Results the aforementioned evaluated multivariate statistical methods, such as discriminant analysis cluster analysis, discriminated according to wine variety geographical origin. Due specific choice analytes investigation, a prediction rate cross-validation 98% could be achieved. aim this study was not only reveal relationships between samples or chemical variables order classify varieties their elemental profile (wine authentication), but also observe annual fluctuation mineral content studied samples.
