abstract Physical properties are often required for the development of post harvest equipment. The study was conducted to investigate the physical properties of Simarouba glauca L. fruit and kernel, namely, dimensions, 1000 unit mass, fruit part fraction, arithmetic mean diameter, geometric mean diameter, surface area, sphericity, aspect ratio, bulk density, true density, porosity and angle of repose. The kernel had 8.51% (w.b.) moisture and 61.04% oil content, which is higher than the fruit and shell. The average fruit length, width, thickness and 1000 unit mass were 21.26, 13.81, 11.03 mm; and 1120.16 g, while the corresponding value for kernel were 13.78, 7.77, 6.71 mm; and 330.26 g, respectively. The sphericity and surface area of fruit were 5.8 and 63.36% more, respectively, than those of kernel. Bulk densities of fruits and kernels were 622.27 and 727.73 kg m-3, the corresponding true densities were 931.96 and 1019.3 kg m-3, and the corresponding porosities were 33.23 and 28.61%, respectively. The angle of repose of fruit and kernel were 31.35 and 35.02, respectively.
