Geographical traceability based on 87Sr/86Sr indicator: A first approach for PDO Lambrusco wines from Modena

Impact of agricultural practice on the Sr isotopic composition of food products: Application to discriminate the geographic origin of olives and olive oil

“…The Sr content of this fraction is clearly linked to the nature of the geological bedrock and to the pedogenic processes that combine mainly the primary minerals alteration and the availability of the organic matter, but it is also controlled by rainfall . Many consider the reservoir consisting of the exchangeable cations to be the major source of base cations for the uptake by the vegetation (Blum, 2000;Gastberger et al, 2000;Takeda et al, 2006;Durante et al, 2013;van der Heijden et al, 2013;Bedel et al, 2016).…”

“…However, the origin and intrinsic properties of some chemical elements are of interest for determining the geographical origin of plants in terms of quality and/or authenticity certifications. In this context, the strontium (Sr) content and isotope composition ( 87 Sr/ 86 Sr ratio) of a plant represents an appropriate tool to discriminate agri-food products (Almeida and Vasconcelos, 2001;Barbaste et al, 2002;Fortunato et al, 2004;Swoboda et al, 2008;Techer et al, 2011;Voerkelius et al, 2010;Durante et al, 2013;Hartman and Richard, 2014;Vinciguerra et al, 2015;Petrini et al, 2015).…”

Elemental Profile and 207Pb/206Pb, 208Pb/206Pb, 204Pb/206Pb, 87Sr/86Sr Isotope Ratio as Fingerprints for Geographical Traceability of Romanian Wines

“…Since the content of 87 Sr in soil varies with geological age and geographical location, the 87 Sr/ 86 Sr isotopic ratio can be used as a tracer for determining the geographical origin of wine (Vorster et al, 2010). Many studies have shown that there is a significant correlation between isotopic ratio 87 Sr/ 86 Sr from wines and soils of origin (Di Paola-Naranjo et al, 2011; Durante et al, 2013), thus representing the starting premise for geographical origin determination. The isotopic ration 87 Sr/ 86 Sr is a well-established tool for dating and tracing the origin of rocks and also minerals (Capo et al, 1998) with special interest of wine traceability.…”

“…The isotopic ration 87 Sr/ 86 Sr is a well-established tool for dating and tracing the origin of rocks and also minerals (Capo et al, 1998) with special interest of wine traceability. Several studies on its use for wine geographical origin assessment can be found in literature (Horn et al, 1993;Almeida and Vasconcelos, 2004;Durante et al, 2013;Catarino et al, 2016). Recently, within a research program regarding strategies for wine fingerprinting, the authors confirmed 87 Sr/ 86 Sr as a viable tool for traceability of Romanian PDO and GI wines (Geana et al, 2016), Portuguese PDO, where soils were developed on different geological formations (Martins et al, 2014;Catarino et al, 2016).…”

“…The most used chemical parameters for discriminating the geographical origin of wine are the stable isotope ration of oxygen, carbon and hydrogen (Dordevic et al, 2012;Raco et al, 2015;Geana et al, 2016) and also the elemental composition (Fabani et al, 2010;Selih et al, 2014) including rare elements (Gonzálvez et al, 2009) Sr isotope ratio (Durante et al, 2013;Marchionni et al, 2013;Geana et al, 2016) or a combination of them (Dutra et al, 2011). The ability to differentiate wines by regions through their elemental patterns suggests that elements are mainly regulated by their migration from rock to soil and from vineyard soil to grapes.…”
