Identificação do carbamato de etila durante o armazenamento da cachaça em tonel de carvalho (Quercus sp) e recipiente de vidro

Abstract

The objective of the present study was the identification and quantification of ethyl carbamate (EC), by HPLC-FLD, after different periods of storage in an oak (Quercus sp) barrel and a glass vessel. The concentration of EC in the cachaça samples varied from <LD to 17.46 μg L-1, for the period during which the cachaça was stored in an oak barrel, and <LQ to 18.51 μg L-1 for the cachaça stored in a glass recipient. The storage of the beverage in both the oak barrel and the glass vessel resulted in a significant increase in the concentration of this contaminant.
