Avaliação multivariada da composição fenólica de cachaças envelhecidas em diferentes barris de madeira

Abstract

This study sought to evaluate the phenolic composition of cachaças aged in barrels constructed of oak, jequitibá, chestnut, amburana, balm, bay and cinnamon jatoba employing Principal Component Analysis (PCA). The levels of phenolic compounds were centered on the mean and subjected to ACP. The results indicated that the cachaça aged in chestnut (36 months), oak (48 months) cinnamon and bay differed from the others by possessing a higher content of gallic acid, ellagic acid and eugenol, respectively. The samples aged in amburana (48 months), balsam (36 and 48 months), jequitibá, oak (24 and 36 months) and jatoba showed characteristics similar to one another, highlighting the importance of the ACP analysis to show the effect of the type of wood on the phenolic composition of aged cachaça.
