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.
