Geographical wine traceability is an important topic in the context of wine authentification. Therefore, many researchers have addressed this subject by developing different methodologies based on multivariate analysis of organic and inorganic parameters and also by isotopic signature. The goal of this research was to assess the potential of elemental composition and isotopic signature of lead (207Pb/206Pb, 208Pb/206Pb and 204Pb/206Pb) and strontium (87Sr/86Sr) of wines from three Romanian vineyards, in order to highlight reliable markers for wine geographical origin. The ICP-MS method was used for the concentration determination for 30 elements (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cs, Cu, Fe, Ga, In, K, Li, Mg, Mn, Na, Ni, Pb, Rb, Se, Sr, Tl, V, U, Zn, Hg). In this study 10 wines (2 red and 8 white) obtained from ‘Merlot’, ‘Fetească neagră’, ‘Fetească albă’, ‘Fetească regală’, ‘Băbească gri’, ‘Șarba’, ‘Aligoté’, ‘Sauvignon blanc’, ‘Muscat Ottonel’, ‘Italian Riesling’ cultivars ...

The control of geographic origin is one of a highest priority issue regarding traceability and wine authenticity. The current study aimed to examine whether elemental composition can be used for the discrimination of wines according to geographical origin, taking into account the effects of soil, winemaking process, and year of production. The elemental composition of soils, grapes, musts, and wines from three DO (Designations of Origin) and for two vintage years was determined by using the ICP-MS semi-quantitative method, followed by multivariate statistical analysis. The elemental composition of soils varied according to geological formations, and for some elements, the variation due to soil provenance was also observed in musts and wines. Li, Mn, Sr and rare-earth elements (REE) allowed wine discrimination according to vineyard. Results evidenced the influence of winemaking processes and of vintage year on the wine’s elemental composition. The mineral composition pattern is trans...
Geographical origin identification of Romanian wines by ICP-MS elemental analysis
Food Chemistry, 2013
Trace elemental analysis, besides its ability to determine stable isotopes ratios, represents a possible complementary tool useful to differentiate wines based on their regional origins. Wines and their provenance soils from two major wine producing areas in Southeast Romania ('Valea Calugareasca' and 'Murfatlar'), and also wine from the region of Moldova (Eastern Romania) were analyzed by inductively coupled plasma mass spectrometry (ICP-MS), and statistical data of elemental composition was used to differentiate these wines according to grape type and geographical origin. Moreover, this study gathers relevant elemental trace composition of wines produced in most important Romanian vineyards, thus offering a useful wine differentiation tool by their production district. The results show that the differentiation of Romanian wines according to their provenance is based on the following main elements: Ni, Ag,

Chemometric analysis are used for food authenticity evaluation, correlating botanical and geographical origins with food chemical composition. This research was carried out in order to prove that it is possible linked red wines to Nero d'Avola and Syrah cultivars of Vitis vinifera according to their mineral content, while the values of the physical and chemical parameters do not affect relevantly this discrimination. The levels of mineral elements were determined by ICP-OES and ICP-MS. Samples from cv Nero d'Avola had the highest content of Zn, Cr, Ni, As and Cd, whereas the highest mineral concentration in cv Syrah samples was represented by K, Mg, Cu, and Sb. The research highlights that it is possible linked red wines to Nero d'Avola and Syrah cultivars of V. vinifera according to their mineral contents, adding knowledge to the determination studies of the wine botanical origin.

Background: The determination of micro-, macroelements and heavy metals in the soil-grapevine-wine system is extremely important for the wine industry, the grape and wine quality, and also for consumer health. The quantitative analysis of 10 elements: Na, Ca, Mg, Fe, Cu, Zn, Pb, Cd, Ni, Co were made in soil at different depths and also in grapevines (leaves and canes). For grape juice and wine there were analyzed the concentrations of Cu, Zn, Pb, Ni and Cd on three cultivars Fetească albă, Fetească regală and Riesling italian, located in Turulung vineyard, NW Romania. All the elements were detected using flame atomic absorbtion spectrometry (FAAS).
Soil chemistry and meteorological conditions influence the elemental profiles of West European wines
Food chemistry, 2019
Elemental profiles of wines have been used successfully to distinguish their geographical provenience around the world; however, underlying mechanisms are poorly understood. In this study, Ba, Ca, Mg, Mn and Sr contents were determined in 215 wines from several West European wine-growing areas using an easy-to-perform analysis based on ICP-OES. Major environmental and wine-making parameters (soil type as "calcareous" or not, rainfall, temperature and wine color) were used to explain variations within the dataset. The combined effects of wine-making processes (expressed by wine color) and soil type explained 28.5% of total variance. The effect of climatic conditions explained 24.1% of variance and could be interpreted as intensity of drought stress. Finally, carbonate occurrence in soils and climatic conditions systematically influenced the elemental composition of the wines. These findings provide insights into the mechanisms underlying elemental fingerprinting and allow p...

Determination of heavy metals in soil and wine is very important for wine quality and consumer health, but at the same time it is a complementary tool for differentiating wines according to their geographical origin. In this work, soils and ten brands of wines originated from four major wine-growing areas of Romania (Iaşi, Babadag, Ştefăneşti and Blaj) were considered for performing a multielement (Cr, Ni, Cu, As, Pb, Hg, V, Sr, Mn, Zn, Fe) investigation in order to assess regional specificity. Heavy metals found in the investigated wines were below the limits imposed by European standards (O.I.V.) the elements concentrations following the trend: Zn>Fe>Mn>Sr>Ni>Cr>Cu>Pb>V>Hg>As. For the soils analyzed, the heavy metals content was found to be below the maximum permitted limit, except for Cu (135.45 mg/kg) from the Iaşi vineyard, which was at the permitted limit. The high values obtained for copper may be the result of different treatments with the Borde...
In this work, a method for the determination of major and trace elements in different types of wine samples based on k 0 -instrumental neutron activation analysis (k 0 -INAA) is presented. Results for the content of major and trace elements in different wines from the Republic of Macedonia are presented. Some data were compared using atomic absorption spectrometry (AAS). Mineralized wine samples were irradiated in the carousel facility (CF) of the 250 kW TRIGA Mark II reactor of the Jožef Stefan Institute. The samples were irradiated with a thermal neutron flux of 1.1⋅10 12 cm -2 s -1 for 20 hours. The carousel facility was not rotated during the irradiations. For f (thermal to epithermal flux ratio) and α (parameter which measures the epithermal flux deviation from the ideal (1/E) distribution) determination the "Cd-ratio" method for multi monitor was used. Thin foils or low-concentration alloys were used to minimize self-shielding effects (foils: 125 µm Zr and 50 µm Zn; wires: Al -0.1 % Au and Al -1.0 % Co). The following results were obtained in the CF: f = 27.5 and α = -0.015. The values f and α obtained in this way were used to calculate element concentrations. The activities of irradiated samples were measured on a HPGe detector (ORTEC, USA) with 40% in relative efficiency. The detector was connected to a CANBERRA S100 multichannel analyser. For the peak area evaluation, the HYPERMET-PC programme was used. For elemental concentrations and effective solid angle calculations a software package called KAYZERO/SOLCOI , operated on an IBM-compatible PC, was applied.

Numerous works have shown that the mineral composition of plants is influenced by the element levels in the ground, by fertilization methods, by the physiological aspects typical of the species from which they are produced, as well as by the technological conditions of production when it deals of transformation alimentary products. Therefore the multielement content method represents a valid tool for the determination of the origin of vegetable products. The current review contains the information present in literature concerning the influence of trace element concentration, or of minerals in general, and the stable isotope analysis in the geographical determination of wine origin. The most frequently used analytical techniques for mineral and isotope determination in wines are spettrophotometry by atomic absorption and the techniques evolved from it and the isotope ratio mass spectroscopy. The statistical techniques used are multivariate analysis, as PCA (principal component analysis), DA (discriminant analysis), CA (canonical analysis) and CLA (cluster analysis). These techniques have proven useful in the differentiation of wines and in their classification according to the place of origin.
