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.
