The study aimed to evaluate the characteristics of the physical and mechanical properties of Physalis peruviana . The sample had a moisture content of 76.71±1.10 %wb. The results showed that the P. peruviana physically had an average mass, volume, polar diameter, equatorial diameter, geometric diameter, and surface area ranged from 3.03±0.45 gram, 2.91 cm3, 16.99 mm, 17.53 mm, 17.10 mm, and 927.61 mm2, respectively. Furthermore, the average particle, bulk density, sphericity, aspect ratio, and porosity ranged from 1.04 gr/cm3, 0.62 gr/cm3, 97.97±2.64%, 97.00±3.92%, and 59.41±3.39 %, respectively. Based on mechanical properties analysis, P. peruviana had hardness, gumminess, adhesiveness, and chewiness ranged from 1640.52± 371.71 g. force, 406.67±171.75 g. force, -1.22±1.00 g.force/sec, and 102.19±41.60 g. force/sec. The average cohesiveness, resilience, and springiness of P. peruviana ranged from 0.25±0.07 g/force, 0.11±0.04 g/force, 0.25±0.02 g/force, respectively. Regarding the angle of repose, the highest angle of repose occurred on the surface of stainless steel. In general, the angle of repose had a tangential relationship with the samples’ physical biometric dimensions.
