Resumo
A cachaça, bebida fermento-destilada mais consumida no Brasil, tem uma produção anual estimada em 1,3 bilhão de litros, envolvendo mais de 5 mil marcas registradas e a estimativa é de que existam ainda mais de 40 mil produtores não registrados, em todo país. Para obtermos uma cachaça de boa qualidade, além dos cuidados que devem ser tomados durante seu processo de produção e o atendimento às exigências dos padrões de qualidade exigidos pela Legislação Brasileira, essa bebida deve apresentar qualidade sensorial que satisfaça ou supere as expectativas de seus consumidores. Para isso, os compostos voláteis, tais como ésteres, álcoois superiores e compostos carbonílicos, assumem papel de grande importância na caracterização do aroma e sabor característicos da cachaça. O processo de bidestilação para a obtenção da cachaça vem sendo atualmente estudado mas, com a revisão bilbiográfica, pode-se observar que o perfil aromático dessa nova bebida e da cachaça tradicionalmente obtida é geralmente determinado pelos compostos presentes maioritariamente nessas bebidas, exigidos pela Legislação Brasileira, não se conhecendo o efeito desse processo de destilação nos compostos odoríferos importantes para a qualidade sensorial dessas bebidas. Portanto, os compostos voláteis de amostras de cachaça obtidas tradicionalmente e pelo processo de bidestilação, submetidas ou não ao processo de envelhecimento, foram determinados por CG-Olfatometria, sendo encontrados 54 compostos odorantes importantes, dos quais 47 foram identificados. Essa técnica evidenciou a maior complexidade aromática das cachaças bidestiladas, pela presença, nessas amostras, de um maior número de compostos odorantes importantes, em relação às amostras tradicionais. Dentre os compostos considerados importantes para o aroma da cachaça, 12 foram destacados...
The sugar cane spirit, distilled beverage yeast-most consumed in Brazil, has an estimated annual production of 1.3 billion liters, involving more than 5000 trademark and it is estimated that there are more than 40 thousand farmers not registered in any country. To obtain a good quality of sugar cane spit, and care should be taken during their production process and meeting the requirements of the quality standards required by Brazilian law, this drink should have sensory quality that meets or exceeds the expectations of its consumers. For this, the volatile compounds such as esters, higher alcohols and carbonyl compounds, assume major role in the characterization of the aroma and flavor of sugar cane spirit. The process of bidistilled for obtaining the cachaça is currently being studied but with the bibliography review, we can observe that the flavor profile of this new beverage and sugar cane spirit traditionally obtained is generally determined mainly by compounds present in these beverages, as required by Brazilian law , not knowing that the effect distillation process in important odoriferous compounds for the sensory quality of these beverages. Therefore, the volatiles compounds of sugar cane spirit samples traditionally obtained and obtained by the bidistilled process, subjected or not to the aging process were determined by GC-Olfactometry, founded 54 important odorant compounds, 47 of which were identified. This technique showed the greater aromatic complexity of bidistilled cachaças by the presence in these samples, a greater number of important odorous compounds for traditional samples. Among the compounds considered important to the aroma of sugar cane spirit, 12 were highlighted for their contribution in defining the aromatic base of this beverage, and 10 were considered responsible for promoting the sensory differences observed among samples. The Quantitative Descriptive Analysis of cachaça samples was carried out by nine judg
