Multi-element and multi-isotope-ratio analysis to determine the geographical origin of foods in the European Union
TL;DR: In this paper, the authors reviewed the application of multi-element and multi-isotope methods and the statistical tools used to determine the geographical origin of food and beverages in the European Union from 2008 to early 2012.
Journal ArticleDOI
Progress in authentication, typification and traceability of grapes and wines by chemometric approaches
TL;DR: The recent findings on wine typification and authentication herein reviewed, highlight that several challenges need to be solved in order to improve the assessment of wine authenticity and confirm potential mistakes or product adulteration.
Journal ArticleDOI
Trace-element composition and stable-isotope ratio for discrimination of foods with Protected Designation of Origin
TL;DR: In this article, the authors review the literature on authentication of foods with Protected Designation of Origin (PDO) from their trace-element composition or stable-isotope ratios in order to evaluate the state of the art of this field and to identify the main parameters of analytical techniques and chemometric data treatments that permit accurate discrimination of samples of different geographical origins and with different characteristics.

TL;DR: This is the first report combining independent variables, constructing a fingerprint including elemental composition, isotopic, and polyphenol patterns to differentiate wines, matching part of this fingerprint with the soil provenance.
Journal ArticleDOI
Characterization of wines using compositional profiles and chemometrics
TL;DR: A review of strategies for characterizing wines based on compositional profiles as sources of information can be found in this paper, where the authors discuss strategies to characterize wines using compositional information.

The determination of the authenticity of wine from its trace element composition
TL;DR: In this article, multi-element analysis of 112 Spanish and English wines by inductively coupled plasma mass spectrometry (ICP-MS) was undertaken to ascertain whether or not this method could provide data for determining the region of origin of wine.
