The knowledge of engineering properties is vital in designing postharvest equipment. In this research work, some physical and thermal properties of kariya (Hildegardia barteri) kernel were studied with respect to moisture content in the range of 8.83 to 27.42 % dry basis (d.b). The surface area, geometric mean diameter, arithmetic mean diameter, bulk density, true density, aspect ratio, sphericity, volume and porosity ranged between 154.09 and 200.29 mm2, 7.75 and 8.64 mm, 144.40 and 216.66 mm, 0.65 and 0.72 kg/m3, 1.01 and 1.29 kg/m3, 0.64 and 0.69 mm3, 12.40 and 14.59, 226.94 and 340.23 cm3 and 40.28 and 98.46, respectively. The static coefficient of friction ranged from 0.42 and 0.53; 0.40 and 0.51; 0.42 and 0.52 for galvanized steel, stainless steel and glass surface respectively. Thermal properties were found to increase from 0.17 to 0.51 kJ/kgK, 1.2 to 2.0 x 10-7m2/s and 1.43 to 2.73 W/moC, for specific heat, thermal diffusivity and thermal conductivity respectively. Models were established for all the parameters measured for the kariya kernel as a function of moisture content, with high correlation coefficients. These models can adequately predict the properties within the moisture range examined.
