The 87Sr/86Sr strontium isotopic systematics applied to Glera vineyards: A tracer for the geographical origin of the Prosecco

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

“…environments, whereas its isotope signature is often considered as a reliable tracer of the geographic origin of agri-food products, by assuming that it is mainly derived from geological reservoirs of the cultivated area (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). However, little is still known about the contribution of the agricultural practice on the bioavailable reservoir, especially the impact of irrigation and fertilization.…”

“…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).…”

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.…”

Food traceability using the 87Sr/86Sr isotopic ratio mass spectrometry

“…This technique was indeed able to detect chaptalization, adding water, and by determining geographical origin and vintage of the wine. In the following years, numerous studies on the geographical traceability of wine were carried out with the use of the 87 Sr/ 86 Sr ratio in different countries: South Africa [57]; Argentina [58]; Romania [59]; Portugal [60]; Italy [61][62][63][64]; and Canada [65]. Subsequently, we will briefly examine and comment on one of these papers, because of its particularly interesting results.…”
