Today, preserving the quality and reducing the losses of agricultural products is an important topic and has attracted the attention of many scholars in the field. This study aims at investigating the engineering properties (physical, mechanical, and hydrodynamic properties) of cantaloupe in order to manage and reduce the losses that is produced postharvest. The results show that the mean values physical properties measured for the geometric mean diameter, arithmetic mean diameter, sphericity, surface area, volume, and true density of the cantaloupes were 130.13 mm, 130.26 mm, 0.94%, 53,367.59 mm2, 633.30 cm3, and 0.83 g/cm3, respectively. Maximum force required for bruising and shearing cantaloupes in the investigation of their mechanical properties were 248.20 and 108.30 N. The hydrodynamic properties of cantaloupes such as the terminal velocity, the cantaloupes' rise time in the water column, the buoyance force and the drag force were obtained to be equal to 0.12 m/s, 4.10 S, 6.21 N, and 0.11 N, respectively. The results obtained through this study can be used in designing harvest machines, optimization, processing, transport, separation of impurities, and grading equipment for the purpose of reducing cantaloupe waste.
