“…The highest increase was for Pb (particularly in skins), where the content of this element in distilled samples was between 4.0 and 37 times greater than in undistilled ones. Other authors also reported significant Cr and Pb contributions to grape pomace samples during both vinification and distillation …”

“…The presence of heavy metals and micronutrients in winery residues could be attributed to vineyard treatment with fertilizers and plant protection agents (pesticides and fungicides) during the development of the crop . Another important source of heavy metals (particularly Cr, Cd, and Pb) in winery residues is the equipment used in the winemaking process, and even in distillery industries where the distilled grape pomace is generated …”

BACKGROUND The possible agricultural use of grape pomace could be limited by the content and mobility of metals. This is influenced by many factors. In this study, the abundance and availability of heavy metals and essential nutrients were evaluated comprehensively in different grape pomace residues from winemaking of five white and red grape varieties, before and after the distillation process. RESULTS The total metal content found in grape pomace skins and seeds confirmed that there was greater metal accumulation in skins than in the corresponding seeds, with the exception of Ca and Mg. The enrichment of all metals (except K) during the distillation stage was confirmed by means of a significant correlation (R = 0.996, P < 0.001) between the metal content obtained in distilled and undistilled samples. Regarding availability, multivariate statistical analysis showed different behavior among elements, but a great similarity for metal mobility in both distilled and undistilled grape pomace samples and in both skins and seeds, except for Mn, Zn and Mg. CONCLUSION The results obtained in this study suggest the potential application of these grape residues as organic fertilizers for agricultural soils, without limitations resulting from heavy metal contamination. © 2019 Society of Chemical Industry

“…It is very important to monitor food products and beverage, including wines, for heavy metal contamination and assess the source of food contamination. Must and wine has a primary content of elemental composition due to natural transfer soil-root-grape-wine [4,5] and a secondary content due to natural [6,7] and artificial contamination [8,9]. The natural content of elemental composition of wine and of other beverage is affected and overlapped by the artificial contamination [10].…”

The influence of the winemaking process on the elemental composition of the Marselan red wine

BACKGROUND The elemental profile of the Marselan wine cycle was studied with a single ion‐beam technique, namely particle‐induced X‐ray emission (PIXE). Samples were collected from all of the major stages involved in the wine cycle, including soil, vine plant, grape, and different stages of wine processing. RESULTS The results show the influence of field practices on the elemental composition of leaves, branches, grapes, and soil. Mechanisms of element precipitation and elimination from the wine were identified through the changes in the elemental concentrations measured during the post‐harvesting processes. The concentrations of some elements, such as Al, Si, K, and Ni, did not vary for grapes collected at different maturation stages. On the other hand, changes in the concentrations of Si, Cl, Ca, Cu, and K were observed right after the maceration and pressing processes in young wine. Finally, the reduction in the Cu concentration during the last stages of the wine cycle is related to its precipitation in the storage tanks. CONCLUSIONS It was found that field practices and winemaking processes played distinct roles in the elemental composition of grapes and wine from different preparation stages. Moreover, PIXE proved to be a suitable analytical tool for the analysis of the whole wine cycle because it handles solid and liquid samples in a clean and straightforward manner. © 2019 Society of Chemical Industry
