Online published on 11 March, 2024. Abstract Effect of moisture content (9.43 to 101.7 and 11.37 to 130.68 % db) on physical properties (geometric, gravimetric and frictional properties of jackfruit seed i.e., firm flesh (Kapa) and soft flesh (Barka) were determined. The geometric properties (linear dimensions, sphericity, geometric mean diameter and surface area), gravimetric properties (bulk density, true density and porosity) and frictional property (angle of repose) were determined at moisture content 9.4, 19.9, 35.9 65.8, 101.7 (% db) for firm flesh (Kapa) and at 11.3, 37.3, 52, 89.5 and 130.6 for soft flesh (Barka). The geometric properties increase with increase in moisture content for both the types of jackfruit seeds. Bulk density, true density increases with increase moisture content while porosity decreases with decrease in moisture content in both types of jackfruit seeds. Bulk density was 626.2-383.7 kg/m3 for firm flesh (Kapa) and 657.6-362.9 kg /m3 soft flesh (Barka). The angle of repose was in range of 57.34-66.71° and 58.39-66.36° for firm flesh (Kapa) and soft flesh (Barka) respectively and it increases at moisture content (9.4 to 101.7 % db) and (11.3 to 130.6 % db) respectively. Top Keywords Firm flesh (Kapa), Soft flesh (Barka), Linear dimensions, Sphericity, Geometric mean diameter and surface area bulk density, Truedensity, Porosity, Angle of repose. Top |
