dc.description.abstract | Hazelnuts' features and price are influenced by their geographical origin, making them susceptible to fraud,
especially counterfeit claims regarding their provenance. Stable isotope analysis is a recognised approach to
establish the geographical origin of foods, yet its potential in hazelnut authentication remains unexplored. In this
prospective study, we assessed multiple isotopic markers in hazelnuts from different origins and evaluated the
most promising variables for geographical authentication by chemometric tools. Our findings indicate that bulk
δ18O, along with δ2H and δ13C in the main fatty acid methyl esters, exhibit significant potential in discriminating
geographical origins, and 87Sr/86Sr analysis could serve as a proficient confirmatory tool. Though no single
marker alone can differentiate between all the studied origins, employing a multi-isotopic approach based on
PLS-DA models achieved up to 92.5 % accuracy in leave-10 %-out cross-validation. These findings will probably
lay the groundwork for developing robust models for hazelnut geographical authentication based on larger
datasets. | ca |
