Influence of regionality and maturation time on the chemical fingerprint of whisky.
2020
International audience; Understanding the chemical composition of whisky and the impact of each step in the manufacturing process provides a basis for responding to the challenges of producing high quality spirits. In this study, the objective was to discriminate whiskies according to their geographical origin and authenticate the maturation time in cask based on the non-volatile profiles. The combination of FT-ICR-MS and chemometrics allowed the distinction of whiskies from four geographical origins in Scotland (Highlands, Lowlands, Speyside and Islay). Statistical modeling was also used to discriminate whiskies according to the maturation time in cask and reveal chemical markers associate…
Utilizzo di traccianti geochimici nella Limonicoltura Siciliana.
2018
Nell’ultimo decennio i consumatori hanno sviluppato un interesse crescente per la tracciabilità dei prodotti agroalimentari in particolare in relazione all’origine geografica. La conoscenza di una possibile relazione chimica tra suolo e prodotti agroalimentari è importante per valutare la provenienza e autenticità dei prodotti. Tutto ciò va a favore del consumatore e si traduce in maggiore sicurezza e qualità dell’alimento. La coltivazione del Limone (Citrus Limon (L.) Osbeck) è una delle più importanti colture al mondo e l'individuazione di potenziali frodi potrebbe essere migliorata studiando la sua composizione chimica che lo lega all’area di origine. Questo studio ha utilizzato le terre…
DETERMINATION OF YLOID IN SOIL AND GRAPEVINE SYSTEM (VITIS VINIFERA L.) BY ICP-MS TECHNIQUE: A HOPEFUL PROXY FOR THE GEOGRAPHICAL CHARACTERIZATION OF…
2013
The rising importance given from legislators and consumers to provenance of food purchased and/or eaten, in last years motivated several researches to identification of the geographical origin of food. The knowledge of a chemistry relationship between the soil and the agricultural products is an important tool for the quality assessment of food. YLOID (Y, La and Lanthanides) have recognized as very useful tracers because of their generally coherent and predictable behavior. This behavior can also be applied to explain the mechanisms of element intake by plants. Current knowledge suggests no preferential sorption of any element in overall root samples as well as in epigeal samples of several…
Distribution of YLOID in soil-grapevine system (Vitis vinifera L.) as tool for geographical characterization of agro-food products. A two years case …

The knowledge of a chemistry relationship between the soil and the agricultural products is an important tool for the quality assessment of food. We studied YLOID (Y, La and lanthanoids), recognized as very useful tracers due their coherent and predictable behavior, to trace and evaluate their distribution from soil to the grape in Vitis vinifera L. Because much of the world’s viticulture is based on grafting, and rootstocks have proved affect vine growth, yield, fruit and wine quality, we carried out experimental trials to analyse the YLOID distribution of two different red cultivars, grafted onto six different rootstocks, on the same soil. The YLOID amounts, the relationship Heavy vs Ligh…
