Physical and mechanical properties of ginger rhizome are helpful in the design of new and appropriate s)'stems for handling, processing, and mechanical slicing. In this study, both physical and mechanical properties of selected Indonesian ginger are investigated and evaluated at different moisture contents (89, 71, 60, 51 and 41 %wet basis). The physical properties included the three axial dimensions, actual volume, true density, the coefficient of static friction and shrinkage. The mechanical properties included puncture' resistance, toughness, and modulus of elasticity. When the moisture content decreased from 89 to 41%. The obtained results showed that the axial dimensions (major; intermediate, and minor) decreased by an average of 26, 79.23, and 87.54%, respectively; the actual volume decreased by an average 60%; the true density increased by an average 43%; and the modulus of elasticity at each moisture level was higher on the lateral orientation than that at longitudinal loading orientation.
