SOMMARIO Campioni di olio extravergine di oliva monovarietale o in blend sono stati ottenuti da quattro cultivar autoctone toscane di Olea Europaea L., e due non autoctone. Tutte le cultivar sono state coltivate in Toscana. I composti organici volatili (VOCs) sono stati analizzati in modo non distruttivo utilizzando un approccio PTR-ToF-MS, che fornisce una definizione autentica del profilo aromatico dell'olio di oliva, grazie all'assenza di pre-trattamento dei campioni. L'approccio analitico ha permesso di identificare il valatoma di ciascun campione di olio, monovarietale o in blend, e di individuare quei VOCs che determinano la qualità e la classe merceologica del prodotto (olio extravergine o vergine di oliva, EVOO o VOO).
SUMMARY Monovarietal and blended extra virgin olive oil samples were obtained from 4 autochthonous Tuscan cultivars of Olea Europaea L., and two non-autochthonous ones. All cultivars were grown in Tuscany. Volatile organic compounds (VOCs) were analyzed non-destructively using a PTR-ToF-MS approach, which allows getting a genuine definition of olive oil aromatic profiles thanks to the absence of pre-treatment of the samples. The analytical approach allowed to identify the volatomic of each monovarietal or blended oil under study, and to determine those VOCs influencing the quality and the merceological class of the product (extra virgin or virgin olive oil, EVOO or VOO)
