‘‘Aceto Balsamico Tradizionale’’ (ABT) is gaining increasing attention due to its peculiar characteristics, not only within the production area. A first approach to understanding the complex ageing process was performed by studying ABT furanic compounds, quantified by HPLC: hydroxymethylfurfural, furoic acid, furfural, and 5-acetoxymethylfurfural (HMF, FA, Fal, AMFA). Also, other parameters, expressing the acidic and sugar contents (pH, total acidity and Brix), were quantified.Furanic compounds arise during the must concentration process. Moreover, they tend to rise on ageing, as a consequence of thewater loss during the process. However, due to the great reactivity of these substances, which rapidly evolve into other compounds, differences in the accumulation kinetics are likely.While the separate analyses of the single variables did not lead to any significant contribution in the understanding of the phenomenainvolved in the product transformation, principal component analysis showed a common trend on ageing for all the studied sets.
