Effect of different hydration temperatures on the sensory, nutritional, and instrumental profile of black beans
ABSTRACT The objective of this study was to evaluate the effect of temperature using different hydration methods on the sensory profile, nutritional value, instrumental color, hardness, and rupture of the tegument, viscosity, and total soluble solids in the broth of common black beans.

Sumario: | ABSTRACT The objective of this study was to evaluate the effect of temperature using different hydration methods on the sensory profile, nutritional value, instrumental color, hardness, and rupture of the tegument, viscosity, and total soluble solids in the broth of common black beans. The black bean, Guapo Brilhante (Phaseolus vulgaris), was analyzed after treatment with different hydration temperatures. The physico-chemical analysis showed that the treatments did not affect the hydration on protein and fiber content. The evaluation of the sensory profile was performed using the Optimized Descriptive Profile test with 16 evaluators. The evaluators recognized differences in the color, rupture, and viscosity attributes; however, a difference was detected in the hardness only in the sample of cooked beans hydrated at 90°C, which was not consistent with instrumental texturometric analysis. When hydration treatments were conducted the soluble solid content of the broth increased and grains were less hard and chewy. In the optimized descriptive profile, the disposal of the water, it was what differentiated sensorial the samples being that the evaluators perceived colors lighter, and with the lower viscosity of the broth. However, the sensory attributes relating to the instruments on the whole, there was a difference between treatments, and correlations for all variables. |
