Physical properties of raw PTS 10 turmeric variety

Author(s): Wasiya Farzana, Pricy Niruba P and Adu Emmanuel Adeyemi
Abstract: A sample of 30 turmeric rhizomes (var. PTS 10) was selected for analysing their physical properties. The average values of their geometric properties viz. length (90.73 ± 12.12 mm), breadth (22.03 ± 2.25 mm), thickness (20.64 ± 2.2mm), Geometric mean diameter (34.45 ± 2.96 mm), Arithmetic mean diameter (44.46 ± 4.49 mm), Square mean diameter (44.46 ± 4.49 mm), Equivalent diameter (48.18 ± 4.41 mm), Aspect ratio (0.25 ± 0.04), Unit volume (12413.53 ± 3185.09mm2), Surface area (3451.72 ± 585.75mm3), sphericity (0.38 ± 0.04), shape factor (0.97 ± 0.03) were reported. The gravimetric properties viz. Bulk density (468.417 ± 3.304kg m-3), True density (785.13±9.141 kg m-3) and Porosity (0.403±0.009 %) were reported. The frictional properties viz. Angle of repose (50.47º), Coefficient of friction for Stainless steel (1.128±0.13), Coefficient of friction for Mild steel (1.172 ±0.097), Coefficient of friction for Galvanized iron (0.903 ±0.012) and Coefficient of friction for Aluminium (0.903±0.023). The rhizomes were classified based on size into different grades.
