The several physical properties of a new registered common bean cultivar ‘Elkoca-05’ were determined according to three selected moisture content namely, 7.50, 15.28, and 19.85% d.b. In addition, some chemical and color parameter of the grain were studied. The average length, width, and thickness of grain were 14.38, 6.83, and 5.86 mm at 7.50% d.b moisture content. The values of bulk density of the grains were determined as 811.57, 755.17 and 726.10 kg m-3 at the 7.50, 15.28 and 19.85% moisture content. The coefficients of dynamic friction increased from 0.173 to 0.353, 0.174 to 0.261, and 0.214 to 0.316 for steel, plywood, and wood with increasing moisture content. The force of rupture decreased from 138.09 to 100.65 N with increasing moisture content. The antioxidant activity and phenolic content of grains were found to be 53.53%, and 23.91 mgGAE mg-1 d.b.
