Abstract
The presence of lactic acid bacteria (LAB) in oak barrels induces an increase in wood volatile compounds concentration. This phenomenon could be due to the glycosidic activity of LAB. The glucosidic precursor of a major woody aroma compound (oak lactone) was identified and quantified in oak wood but no data was available concerning the presence of other flavor precursors in oak wood. This study showed that monoglycosidic precursors did not exist in oak, in spirits and in wines. The study was performed by UPLC-FT/MS, using vanillin-β-D-glucopyranoside, vanillin-β-D-xylopyranoside, and coniferaldehyde-β-D-glucopyranoside as standards. These molecules were synthesi...
