An analytical approach to Sr isotope ratio determination in Lambrusco wines for geographical traceability purposes

Distribution of YLOID in soil-grapevine system (Vitis vinifera L.) as tool for geographical characterization of agro-food products. A two years case study on different grafting combinations

“…In this context, the knowledge of one or more chemistry relationships between the soil and the agricultural products is an important tool for the quality assessment of food (Baroni et al, 2015;Drivelos & Georgiou, 2012;Durante et al, 2016;Gonzalvez, Armenta, & de la Guardia, 2009;Luykx & van Ruth, 2008;Marchionni et al, 2016;Reid, O'Donnell, & Downey, 2006;Zhao et al, 2013). Among the different techniques and compounds, or class of compounds, used to evidence these relationships, undoubtedly ICP-MS and trace elements have been exploited (Durante et al, 2015;Luykx & van Ruth, 2008;Reid et al, 2006). The significant role played by micro and trace elements in the growth and development of the plants is widely recognized from several studies (Kabata-Pendias, 2001.…”

Conservation of 87 Sr/ 86 Sr isotopic ratios during the winemaking processes of ‘Red’ wines to validate their use as geographic tracer

“…In most of the cases, however, the analytical uncertainty observed in Sr isotopes analyses of wines from literature is larger than most of the rock/soil isotopic variability, giving strong difficulties in matching data of wines with those from geological substrata of the vineyards. Recently, high--precision analytical method for determining 87 Sr/ 86 Sr has been provided enabling then the direct comparison between data on wines with those of the geological and pedological substrata (Boari et al, 2008;Durante et al, 2015;Marchionni et al, 2013;Mercurio et al, 2014;Petrini et al, 2015).…”

“…Previous studies have shown that 87 Sr/ 86 Sr in wines from different vintage years is preserved unless contamination occurred (Boari et al, 2008;Durante et al, 2015;Marchionni et al, 2013;Mercurio et al, 2014;Petrini et al, 2015). In this experimental work, however, we decided to use for each winery 5--7 samples of wine and must from a multiple vintage years population to check the conservation of the amount of radiogenic Sr for wines from the same vineyard through the years then to reinforce the significance of the data used for evaluating the winemaking process.…”

Evaluating Nanofiltration Effect on Wine 87Sr/86Sr Isotopic Ratio and the Robustness of this Geographical Fingerprint

“…Literature is available on the progress made since the first application of the 87 Sr/ 86 Sr isotopic ratio for wine traceability purposes in the 1990s, with an emphasis on the increasing number of studies developed in the last years (Horn et al, 1993;1997;Almeida & Vasconcelos, 2001;Barbaste et al, 2002;Almeida & Vasconcelos, 2004;Vorster et al, 2010;Marchionni et al, 2013;Mercurio et al, 2014;Durante et al, 2015;Marchionni et al, 2016).…”
