Abstract
The objective of this work was to determine some of the physical properties of naturally aged brown rice which
may influence the rice processing operations. The physical properties Length or Longitudinal (L), Width (W), Thickness
(T), Mass (M) and Volume (V) were measured and the following results were obtained: the average Length, Width,
Thickness, Equivalent diameter, Sphericity, Aspect ratio, Surface area, Bulk density, true density, Porosity, 1000 grains
weight and Angle of repose were 4.81 mm, 2.12 mm, 1.84 mm, 3.18 mm, 40.74%, 0.42, 26.58 mm2, 740.6 kg/m3, 1276.32
kg/m3, 43.18, 19.53 g and 30.68o respectively. From the color analysis of brown rice, L*, a* and b* values were ranged
from 58.10 to 62.19, 4.23 to 6.73, and 22.41 to 24.29 respectively. The calculated cooking properties like Optimum
cooking time, Elongation ratio, Solid loss in gruel and Width expansion ratio were 25.88 mins, 1.39 %, 3.53 and 1.74
respectively. The information of the present study would be useful for designing the post-harvest machineries for
processing and storage structures in food processing industry.
