| Some moisture-dependent physical properties of sour-sop seed were investigated. Results of experiments on rewetted sour-sop seed showed increasing in length, width, thickness, arithmetic and geometric mean diameter, volume, surface area, sphericity, and 1000 seeds weight from 14.91-15.69, 8.71-9.24, 5.39-5.56, 9.67 - 10.16, 8.81 - 9.27 mm, 0.57 – 11.67 cm3, 244.98 - 270.89 mm2, 0.56 - 0.59 and 255.7 – 285 g, respectively within moisture range of 8 – 32.5% (db). An increasing trend for bulk density and true density was observed from 0.52 – 0.59 g/cm3 and 0.47 – 0.60 gcm-3. Porosity of the seed decreased from 9.62 – 4.73 %. Angle of repose was increased linearly from 25.7 – 33.3o with increase in moisture content from 8.0 – 32.5% (db). At all moisture... |
