Physical properties of cassava (Manihot esculenta crantz) root and physico-chemical properties of its starch

In present investigation the physical properties of Cassava root and physico-chemical properties of its starch have been determined. Physical properties of cassava root such as size, shape, True density, Bulk density and porosity was studied. Also physico-chemical properties of cassava starch such as ash content, pH, Moisture content, Gelatinization temperature, Water absorption capacity, Bulk density, Particle size, Swelling volume, Swelling power and Solubility were investigated. The cassava root has average values of length, head diameter (D_H), middle diameter (D_M), tail diameter (D_T), sphericity, true density, bulk density and porosity were 254.58 ± ± 36.44 mm, 44.31 ± 7.11 mm, 38.58 ± 7.42 mm, 22.04 ± 2.80 mm, 1.136 ± 0.027 g/cc, 0.498 ± 0.028 g/cc and 56.14 ± 2.701 % respectively. The cassava starch contains average values of ash content, pH, bulk density, particle size, moisture content, gelatinization temperature, water absorption capacity, swelling volume, swelling power and solubility were 0.61 ± 0.04 %, 5.28 ± 0.45, 0.54 ± 0.054 g/cc, 6.12 ± 1.829 μm, 11.41 ± 0.007 %, 73.00 ± 3.57 °C, 1.09 ± 0.05 g/g, 1.42 ± 0.231 ml, 8.73 ± 0.794 g/g and 1.744 ± 0.335 % respectively.
