Determination of Some Physical Properties of Cornelian Cherries (Cornus mas L,)

In this study, the physical properties were determined for one type of Cornelian cherry (Cornus mas L.) fruit and pit from the Alamout region of Qazvin. The average values for length, width, thickness, 1000 fruit mass, unit mass, geometric mean diameter, unit volume, surface and projected areas, sphericity, fruit (true) and bulk densities, porosity and terminal velocity were 18.91, 13.74, 13.33 mm, 2309.78 and 2.31 g, 15.12 mm, 1841.96 mm3. 722.65 mm2, 180.66 mm2, 80.21%, 1.10 g/cm3, 0.63 g/cm3, 43.30% and 13.8 m/s, respectively. The respective values for the pits were 13.61, 6.07, 5.79 mm, 299.67 and 0.3g, 7.81 mm, 252.93 mm3, 192.57 mm2, 48.14 mm2, 57.59%, 1.21 g/cm3, 0.68 g/cm3, 44.05% and 7.4 m/s. The flesh/pit ratio obtained was 6.8. The static coefficient of friction was 0.38 for galvanized iron, 0.33 for plexiglass, 0.34 for steel and 0.43 for plywood.
