Author(s): MK Ghosal and Jyoti Ranjan Rath
Abstract: Some physical properties of groundnut pod and kernel of variety TMV2, widely cultivated in Odisha, India, were evaluated as a function of moisture content. The physical properties were studied as dependent variables and moisture content as independent variable. The different moisture contents during the study were 8.68, 9.57, 11.31, 14.46, 18.47, 20.08 and 22.39% (d.b) for the pod and 10.98, 13.57, 16.31, 20.46, 22.47, 23.08 and 24.39% (d.b.) for the kernels. The results revealed that at an increasing moisture content 8.68-22.39% (d.b.) for pods, the average length, width, thickness, arithmetic mean diameter, geometric mean diameter, sphericity, surface area, bulk density, true density, porosity, 1000-unit mass, angle of repose and crushing strength were respectively 24.32-27.42 mm, 11.13-13.08 mm, 11.54-13.74 mm, 15.67-18.08 mm, 14.54-17.01 mm, 0.59-0.629, 668.15-818.23 mm2, 255.12-150.98 kg/m3, 470.53-810.56 kg/m3, 44.36-81.37%, 798.23-1053.35 g, 39.61-43.01 degrees and 11.23-8.07 N. Similarly, for the kernels at an increasing moisture contents 10.98-24.39% (d.b.), the corresponding values were respectively 10.32-10.67 mm, 6.84-7.93 mm, 6.72-7.57 mm, 7.96-8.72 mm, 7.79-8.62 mm, 0.75-0.80, 187.43-201.24 mm2, 547.65-477.86 kg/m3, 950.56-1062.89 kg/m3, 42.38-55.04%, 294.89-546.78 g, 30.99-38.12 degrees and 7.23-4.45 N. The mean static coefficient of friction on GI sheet, plywood and plastic sheet increased at increasing moisture content for both pods and kernels. Information obtained through the experiments would not only be the useful data for engineer in designing planting and post-harvest equipment of groundnut but also for food scientists, food processor and plant breeders.
