Abstract
Este trabalho determinou aspectos da composição química e aceitação sensorial da aguardente de cana-de-açúcar envelhecida por 3 anos em tonéis de diferentes madeiras (amendoim, araruva, cabreúva, carvalho, cerejeira, grápia, ipê-roxo, jequitibá e pereira). O destilado alcoólico simples que originou a aguardente foi produzido na Destilaria Piloto da ESALQ/USP. Após envelhecimento, as aguardentes foram avaliadas quanto ao grau alcoólico, acidez volátil, furfural, aldeídos, ésteres, álcoois superiores, álcool metílico, cobre, compostos fenólicos totais, cor e aceitação sensorial. Independentemente da madeira com que o tonel foi construído, a aguardente envelhecida apresentou coloração mais escura e maior concentração de acidez volátil, de furfural, de ésteres, de álcoois superiores, de congêneres e de compostos fenólicos totais que o destilado alcoólico simples. Por outro lado, a aguardente envelhecida apresentou menor concentração de aldeídos, de metanol e de cobre que o destilado alcoólico simples. A análise estatística geral, considerando a composição físico-química global das aguardentes envelhecidas nos tonéis das diferentes madeiras indicou similaridades entre as aguardentes envelhecidas nos tonéis de amendoim, araruva e jequitibá; entre as aguardentes envelhecidas nos tonéis de cabreúva e pereira; e entre as aguardentes envelhecidas nos tonéis de carvalho, cerejeira, grápia e ipê-roxo. A aguardente envelhecida nos tonéis das diferentes madeiras manteve-se dentro de todos os padrões de qualidade estabelecidos pela legislação nacional em vigor. A aguardente envelhecida na madeira carvalho foi a que apresentou a melhor aceitação sensorial. Dentre as madeiras nacionais, ipê-roxo, amendoim, cabreúva, cerejeira e pereira foram aquelas que propiciaram as melhores qualidades sensoriais à aguardente.
This study evaluated some aspects of the chemical composition and sensorial acceptance of sugar cane spirit aged for 3 years in casks of different types of wood (peanut wood, araruva or striped wood, red cabreuva, oak, cherrywood, Brazilian gold wood, purple tabebuia, cariniana legalis, and pear tree). The simple alcoholic distillate which originated the sugar cane spirit was produced at the Distillery of ESALQ/USP. After aging, the sugar cane spirits were analyzed in terms of ethanol concentrations o, volatile acidity, furfural, aldehydes, esters, higher alcohols, methanol, copper, total phenolic compounds, color, and sensorial acceptance. Regardless the type of wood the casks were made of, the aged sugar cane spirits became darker and presented higher concentrations of volatile acidity, furfural, esters, higher alcohols, congeners, and total phenolic compounds than the simple alcoholic distillate. On the other hand, the aged sugar cane spirits presented lower concentrations of aldehydes, methanol, and copper than the simple alcoholic distillate. The statistical analysis, considering the global physicochemical composition of the sugar cane spirits aged in the casks made of different types of wood, showed similarities among the sugar cane spirits aged in the casks of peanut wood, araruva or striped wood, and cariniana legalis. It also indicates similarities among the sugar cane spirits aged in the casks of red cabreuva and pear tree and among the sugar cane spirits aged in the casks of oak, cherrywood, Brazilian gold wood, and purple tabebuia. The sugar cane spirits aged in the casks of the different types of wood were in accordance with the composition and quality standards established by the Brazilian laws. The sugar cane spirit aged in oak presented the best sensorial acceptance. Among the Brazilian woods, purple tabebuia, peanut wood, red cabreuva, cherrywood and pear tree were those that produced sugar cane spirits with better sensorial qualities.
