The objective of this study was to evaluate the effect of drying temperature on physical properties of soybeans. To evaluate the effect of temperature, soybean samples with an initial moisture content of 0.244 (db) were dried in an standard hot air oven at temperatures of 40, 50, 60, 70 and 80 °C until reaching the final moisture content of 0.136 (db), followed by determining the physical properties: angle of repose, bulk density, real density, one thousand grain weight, color and electrical conductivity of the solution of the soybean exudates. It was noted that the drying temperature significantly influenced the physical properties of soybeans, resulting in increased angle of repose and electrical conductivity of the exudate solutions. The bulk and real densities, one thousand grain weight and the characteristic color of soybeans decreased with increasing drying temperature. It was concluded that as the drying temperature increase there was a decrease in quality of the grains analyzed.
