Abstract

This work was conducted to characterise the physical and mechanical properties of Physalis angulata. At a moisture content of 76.50 ± 1.10% wb, the study showed that the average polar, equatorial and geometric diameters were 13.49 ± 0.69 mm, 12.92±0.76 mm, 13.10±0.66 mm. The surface area, mass and volume were 540.19±54.55 mm2, 1.39 ± 0.20 gr and 2.63 ± 0.47 cm3 respectively. The particle and bulk densities were 0.53 ± 0.04 gr/cm3 and 0.42± 0.005 gr/cm3. The sphericity, aspect ratio and porosity ranged from, 97.17 ± 3.51 %, 95.84 ± 5.18%, and 20.26 ± 6.63% respectively. The fruits were spherical, and the colour was pale yellow with the value of CIE l*a*b* and CIE l*c*h* of (37.80 ± 0.010, 1.85 ± 0.023, 10.79 ± 0.006), and (37.80 ± 0.010, 10.95 ± 0.007, 0.002 ± 0.002) respectively. The average hardness, gumminess, adhesiveness, chewiness, cohesiveness , resilience and springiness ranged from 625.01± 101.97 gf, 346.74±64.28 gf, -2.27± 0.60 gf/sec, 27.41±5.79 gf/sec, 0.57± 0.13, 0.32 ± 0.12 and 0.08 ± 0.008 respectively. The mean angle of repose on stainless steel, aluminium, acrylic and plywood ranged from 7.97± 3.200, 9.23±3.730, 8.77±3.740 and 7.47 ± 2.910 respectively.
