“…Indeed, drought stress is also a variable parameter that influences the isotopic content, thus it is also possible to discriminate between plants belonging to the same species grown in different years and at different locations, enabling fraud detection for the origin of commodities. This method is already of common use to fight fraud in wines [37] or honeys [38,39], for which frauds about the origin are not rare. They are therefore usable for cosmetic ingredients for which a region of origin is claimed.…”

“…The most used chemical parameters for discriminating the geographical origin of wines are the stable isotope ratios of hydrogen, carbon, and oxygen (Adami et al 2010;Dordevic et al 2012;Raco et al 2015), and also the elemental composition (Fabani et al 2010;Martin et al 2012;Selih et al 2014) including rare earth elements (Gonzálvez et al 2009) and 87 Sr/ 86 Sr isotope ratio (Marchionni et al 2013;Durante et al 2015) or a combination of them (Dutra et al 2011).…”

Elemental Profile and 87Sr/86Sr Isotope Ratio as Fingerprints for Geographical Traceability of Wines: an Approach on Romanian Wines

et al. 2016

Wine geographical traceability is an important topic in the context of wine authentication and for that, many researchers worldwide have addressed this subject by developing different methodologies based on multivariate analysis of natural chemical composition data (inorganic or organic parameters) and isotopic signature. The goal of this work was to assess the potential of elemental composition and strontium isotope ratio ( 87 Sr/ 86 Sr) of wines from important wineproducing regions in Romania, located in relatively small geographical areas, in order to highlight reliable markers for wine geographical origin discrimination. Elemental profile determinations were performed by ICP-MS, GFAAS, and FAAS techniques after microwave acid digestion of the wine samples. The 87 Sr/ 86 Sr isotope ratio of the resulted extracts was determined by quadrupole inductively coupled plasma mass spectrometry (Q-ICP-MS), after separating strontium and rubidium using cation-exchange chromatography with Dowex 50W-X8 resin and the complexation ability of the carboxylic acid EDTA. The variation of elemental composition (Ga, Sr, and Al), Ca/Sr ratio, and the 87 Sr/ 86 Sr ratio of the investigated wine clearly demonstrated that these variables are suitable tracers for wine geographic origin determination. The proposed methodology allowed a 100 % successful classification of wines according to the region of provenance.

“…In previous work, the stable isotopes of wine water (d 18 O, d 2 H) and ethanol (d 13 C) have been used to authenticate the location of wine production (Christoph, Rossmann, Schlicht, & Voerkelius (2009, chap. 11);Calderone & Guillou, 2008;Raco, Dotsika, Poutoukis, Battaglini, & Chantzi 2015).…”

Keywords:Isotope ratio mass spectrometry Gas chromatography Geographic origin Food products authenticity Linear discriminant analysis Likelihood ratio Bell peppers Capsicum annuum a b s t r a c t Two approaches were investigated to discriminate between bell peppers of different geographic origins. Firstly, d 18 O fruit water and corresponding source water were analyzed and correlated to the regional GNIP (Global Network of Isotopes in Precipitation) values. The water and GNIP data showed good correlation with the pepper data, with constant isotope fractionation of about À4. Secondly, compoundspecific stable hydrogen isotope data was used for classification. Using n-alkane fingerprinting data, both linear discriminant analysis (LDA) and a likelihood-based classification, using the kernel-density smoothed data, were developed to discriminate between peppers from different origins. Both methods were evaluated using the d 2 H values and n-alkanes relative composition as variables. Misclassification rates were calculated using a Monte-Carlo 5-fold cross-validation procedure. Comparable overall classification performance was achieved, however, the two methods showed sensitivity to different samples. The combined values of d 2 H IRMS, and complimentary information regarding the relative abundance of four main alkanes in bell pepper fruit water, has proven effective for geographic origin discrimination. Evaluation of the rarity of observing particular ranges for these characteristics coul...
