Cellulose is commonly degraded by the thermal treatment of wood during coopering giving rise to HMF and 5- methylfurfural, while hemicellulose can generate pentose by hydrolysis, and posteriorly, furfural and its derivatives. Lignin transformations during ageing process of distillates are among the most important factors that may influence the quality of aged wine spirit (WS).engWoodCelluloseLigninconference object
