O objetivo dessa pesquisa foi o de avaliar os aspectos sensoriais do feijão preto submetido à radiação gama do 60Co. O estudo envolveu oito provadores, na faixa etária de 17 a 23 anos, selecionados e treinados para Análise Descritiva Quantitativa. Os provadores verificaram alterações quanto à aparência, aroma, sabor e textura em feijão preto irradiado com doses 2, 4, 6, 8 e 10kGy e feijão preto não irradiado. Para a análise estatística dos resultados obtidos foram aplicados, o teste F, ANOVA e o teste de Tukey (5%) com o uso de computadores e do programa específico para análise sensorial Compusense Five e SAS. As amostras irradiadas apresentaram diminuição do sabor amargo, cor acentuada e brilhante e a não irradiada textura seca. Deste modo, a irradiação como método de conservação pode ser utilizada para o feijão preto com as doses avaliadas no presente estudo. The objective of this research was to evaluate the sensory aspects of black beans submitted to gamma radiation from 60Co. The study involved eight panelists, between 17 to 23 years old, who were selected and trained for the descriptive analysis of appearance, aroma, flavor and texture. The panelists analyzed alterations of appearance, aroma, flavor and texture of non-irradiated and irradiated black beans with doses 2, 4, 6, 8 and 10kGy. The results were analyzed by test F, ANOVA and the Tukey test (5%), with the use of computers and the sensory analysis software Compusense Five and SAS. The results showed that irradiated samples decreased the bitter flavor, accentuated color and brightness and samples non-irradiated dry texture. The radiation treatment is a good method for conservation of black beans in doses evaluated in this study
