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

Abstract

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

Machine learning technique unraveled subspecies‐specific ionomic variation with the preferential mineral enrichment in rice

“…The macroelements such as Ca, K, Mg, Na, P, and S in the 14 selected rice samples are considerably higher than the reported content elsewhere (da Silva et al, 2013;Pasvanka et al, 2021), (Figure 5). The macro-element contents (Ca, K, Mg, N, Na, P, and S) do not significantly differ across the selected superior rice genotypes.…”

Inductively Coupled Plasma-Mass Spectrometry (ICP-MS), a Useful Tool in Authenticity of Agricultural Products’ and Foods’ Origin

“…According to our knowledge, the forementioned studies were the first endeavors to distinguish diverse varieties and origins of wines with the employment of ICP-MS. Since then, several studies [ 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 ] ( Table 2 ) have been carried out on the elemental determination and correlation among various wine varieties, grapes, and soils aiming to trace elements which would be excellent markers for the authentication of geographical origin. In 2021, Wang’s group compared the elemental profile and the variations from soil to grapes and wines from diverse Chinese regions.…”

Atomic spectrometry update: review of advances in the analysis of clinical and biological materials, foods and beverages

“…Elemental profiles of Greek wines from different harvests were obtained by Pasvanka et al 191 using ICP-MS to measure the contents of 44 elements. The resulting data were processed using a variety of chemometric models.…”
