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 ( Sr ratio and K/Rb, Ca/Sr of the investigated wine clearly demonstrated that these variables are suitable traces for wine geographical origin determination. The proposed methodology allowed a 100% successful classification of wines according to the region of provenance.
Ecoclimatic conditions have a great influence on grapevine growth and development. Favourable conditions (solar radiation, temperature, humidity etc.) are important and have a positive effect on the growth and fruition. Critical conditions have negative influences resulting in low grape production and wine quality.
The long-term use of copper in viticulture has caused great copper accumulation in vineyard soils, resulting in negative effects on the environment through toxicity to aquatic and soil organisms. The aim of this study was to investigate the copper content in vineyard soils, grapes and wines from Dealu Bujorului, Murfatlar, Tarnave, Iasi and Ştefăneşti vineyards. The ICP-MS method was used for copper determination in vineyard soil, grape must and wine. Copper concentration in red wine samples was significantly higher than in the white wine samples. Values for Transfer Factor and Mobility Ratio indicates that Vitis vinifera L. does not allow the accumulation of copper from vineyard soil in must grape and wine. The copper concentration in grapes, must and wine has been influenced by the copper concentration in soils, by copper fungicide used to protect the vine and by other factors such as the biological specificity of cultivars during growth.
Daily consumption, wine contributes to the requirements of essential elements, such as Ca, Fe, Mn, Mo, Co, Cr, K, Ni, Se and Zn for humans. However, the presence of significant amount of heavy metal in wine may harm the health of consumers. The present work is aimed at establishing the heavy metal content in red wines from Dealu Bujorului vineyard using ICP-MS method for the determination of metals content. In this study 3 red wines obtained from 'Băbească neagră', 'Negru Aromat' and 'Burgund Mare' cultivars were investigated. The wine samples were obtained from micro-wine production under conditions of 2014, 2015, 2016
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
