Abstract
In this study, four tuber sizes (28

45
mm, 45
S2
55
mm, 55
S3
65 mm and 
S4
65 mm) and three potato cultivars (Jelly, Milva and Sante) were used to assess the variations of physico-mechanical, chemical and colour properties depending on tuber size and potato cultivars. Physico-mechanical properties (geometric mean diameter, sphericity, surface area, bulk and tuber densities, volume, static coefficient of friction, puncture force and deformation), chemical properties (pH, total acidity [TA] and total soluble solid content [TSSC]), and colour characteristics (L
, a
, b
) were determined. The physico-mechanical (geometric properties and puncture force) and chemical properties of potatoes were significantly affected by tuber sizes and cultivars, respectively. pH, TA and TSSC of potato tuber were higher in Milva, TA was higher in Jelly and TSSC was higher in Sante than in those of the other cultivars, respectively.
