Teores de carbamato de etila e outros componentes secundários em diferentes aguardentes produzidas em Minas Gerais

Abstract

Minas Gerais is considered the most productive state of artisanal spirits, its manufacturers are seeking more and more new implements and technologies to make their product more suitable to the market. Similarly, researches have been carried out aiming contribute to this progress. Thus, this work had as a goal, to evaluate the quality of spirits in three different regions in Minas Gerais state. It was analyzed the carbamate ethyl concentrations and other compounds, as wellas, alcoholic degree, volatile acidity, superior alcohol, aldehyde, steres, methanol, furfural and copper. The samples of spirits were analyzed according the patterns of identily and quality estabilished by the legislation in Brazil. The physic chemical analyses were carried out at the physic chemical analysis laboratory of spirits (LAFQA/DQI) at Federal University of Lavras. The carbamate ethyl substances were determined by gaz chromatography coupled to spectrometer of masses and performed in the chemical larb of spirits, São Carlos institute, São Paulo university. The concentrations of carbamate ethyl varied frour one sample to another and from a region to another. The values obtained varied from non detected at 643,5 µgL-1, with only one region not following the legislation (150 µgL-1). However further studies with several samples should be carried out in the region. Most of compounds of the studied spirits were present into the limits estabilished by the legislation.
