Resumen:
The TRACE project was a five year research project funded by the European Commission that aimed to establish food provenance using trace element, isotopic and genetic analysis. TRACE was an integrated project which involved research centers from Europe, South America and China. European costumers have a growing interest for high quality food with clear regional identity. TRACE has developed methods and systems for verifying species, geographical and production origin and methods that can discriminate between adulterated and authentic products and sometimes quantify the adulterant (Brereton, 2010). For the validation of the prediction model it was necessary to demonstrate that the model could be expanded outside of Europe. The expansion to Argentina increased the capability of the prediction model to be used to differentiate between European food products and those from one of its importing countries. Five provinces of Argentina were selected for the Project: Buenos Aires, Córdoba, Entre Ríos, San Juan and Mendoza covering humid-template areas and semi-arid regions with different geological settings (Figure 1). The investigated commodities were wheat, wine, olive oil, honey and beef. Soils and irrigation waters from the sampled areas were also analyzed. Isotopic ratios of light elements hydrogen (δ2H), carbon (δ13C), nitrogen (δ15N), oxygen (δ18O) and sulfur (δ34S), heavy isotopes ratios (87Sr/86Sr) and trace element contents were measured.
