Resumo
Ações para incentivar a produção de cafés especiais têm resultado no aumento do interesse dos cafeicultores em produzir cafés de qualidade, principalmente no Estado de Minas Gerais. Com base nessa informação, o objetivo desse trabalho foi caracterizar a qualidade de amostras de cafés especiais do Concurso de Qualidade dos Cafés de Minas Gerais principais regiões cafeeiras de Minas Gerais (Sul de Minas, Matas de Minas, Cerrado e Chapadas de Minas), verificando se existe uma relação entre os atributos sensoriais e a região onde foram produzidos. O método adotado foi a análise sensorial onde as variáveis acidez, doçura, corpo, balanço, nota geral, retrogosto, bebida limpa e sabor são analisadas e pontuadas. A Análise estatística adotada foi a de Componentes Principais, uma técnica estatística multivariada, que determina as variáveis de maior influência na formação de cada componente. Em uma análise geral as regiões não foram caracterizadas por um ou mais atributos sensoriais especificamente. Todas as regiões apresentam cafés de qualidade caracterizados por todas as variáveis estudadas.
Actions to encourage the production of specialty coffee have resulted in increased interest from growers in producing quality, mainly in the Minas Gerais State. Based on this information, the purpose of this study was to characterize the quality of coffees for the stages of competitions Quality Coffees of Minas Gerais of the 2009 edition, verify if there was a relationship between sensory attributes and the region where they were produced. Samples of Coffea arabica L. were submitted by producers of the four main coffee regions of Minas Gerais (Sul de Minas, Matas de Minas, Cerrado and Chapada de Minas). The method of sensory analysis was by the sensory analysis with the help of statement of evidence where eight variables are analyzed and scored. The statistical analysis used was principal components of a multivariate statistical technique that allows to determine the variables that influence the formation of each component. In a general analysis, one can note that the regions were not characterized by one or more sensory attributes and that all regions are characterized by different coffees all the variables and quality.
