Abstract:

The purpose of this work was to examine the effect of different saline concentrations on the cooking time of aged bean seeds. This experiment was conducted at the Molecular Genetics and Improvement Institute (IMEGEM / CAV), employing random block design with two repetitions, in a 2 x 4 factorial arrangement (two cultivars and four doses of NaCl). Two cultivars were tested, one belonging to the carioca group (Pérola) and the other belonging to the black group (Uirapuru). After weighing, the grains were imbibed in different sodium chloride (NaCl) concentrations (0g, 5g, 10g and 25g) for 12 hours at 25°C. Subsequently, these grains were submitted to a cooking test, using the Mattson cooking apparatus. It was then possible to determine the NaCl concentrations in which the cooking time presented a significant reduction. The Pérola cultivar cooking time was reduced by 31 minutes by the addition of 11g of NaCl and the Uirapuru cooking time was reduced by 25 minutes by the addition of 16.75g of NaCl.
