Abstract

The main aim of this work was to study the physical, mechanical and chemical properties of potato tubers (Spunta variety), to help in designing and developing of specific machine and their operations. The length, width and thickness of potato tubers values ranged from 60.03 to 89.93, 44.67 to 60.02 and 37.69 to 44.64 mm, respectively for all treatments under study. The geometric mean diameter and arithmetic mean diameter of the potato tubers ranged from 46.41 to 61.97 and 47.96 to 64.86 mm, respectively. The potato tuber mass was 63.72, 119.51 and 152.07 g for small, medium and large of potato tuber size, respectively. The potato tuber volume was 53.54, 112.96 and 135.12 cm3 for small, medium and large of potato tuber size, respectively. The true density of the potato tuber ranged from 1190 to 1125 kg m-3 for all treatments under study. The potato tubers surface area was 67.61, 104.68 and 120.58 cm2 for small, medium and large of potato tuber size, respectively. The sphericity and moisture content potato tuber were 77.30, 75.02 and 68.91 and 83.64, 80.83 and 83.19 % for small, medium and large of potato tuber size, respectively. Total soluble solids, firmness, lightness and repose angle of potato tubers ranged from 4.43 to 4.65, 5.40 to 5.70, 69.93 to 73.22% and 30.61 to 33.04º. The total sugar and reducing sugar of potato tubers were 2.76, 2.30 and 2.55 and 0.49, 0.43 and 0.45 % for small, medium and large of potato tuber size, respectively.
