Abstract

We report for the first time the detection of glucoseacetates in balsamicvinegars. It is well known that during traditional balsamicvinegar (TBV) ageing several modifications occur. In this paper it was experimentally determined that some modifications take also place during the short maturation time of balsamicvinegar of Modena (BVM), with an increase of the esters content due to the reaction between acetic acid and sugars, in particular glucose. The formation of esters was observed both on reference solutions containing glucose and acetic acid, subjected to an accelerated ageing by heating at 50 °C, and on real balsamicvinegar samples. Glucose esters were mainly detected as α- and β-glucopyranose acetates. The formation of fructoseacetates in reference solutions, was also studied, recording a more complex pattern of products. The structures of the esters were determined by GC/MS analyses and NMR spectroscopy.
