Abstract
ABSTRACT: The objective of this research was to determine the mechanical properties of beans (BRSMG Majestuoso) coated with carnauba wax solution. Grains with 0.1481 (d.b.) moisture content was used. Treatments 0, 1 and 2 were respectively defined as the control sample, application of the wax diluted 1/1 (carnauba wax solution/water) and application of carnauba wax without dilution. Uniaxial compression tests were performed in the universal test apparatus, TA HD Texture Analyzer with 500 N load cell. Compression tests were carried out during the storage period of in-nature grains, in those that underwent the hydration process at 40 and 50 °C of temperature and in grains during the cooking process. Only the storage time had a significant effect (P<0.05) on the rupture force and the proportional deformity module. Hydration and cooking of the grains provided a reduction in the values of the studied variables.
