| Abstract | ||
| The aim of this research work was to determine the physical and elasticity characteristics of date fruits (Phoenix dactylifera) cv Sukari. The physical characteristic included the date mass, volume, dimensions, moisture content, bulk density, flesh thickness, projected area, and elasticity of fruits, also seed mass and volume. Meanwhile, the elasticity characteristics of fruit included the stiffness coefficient (sc), bioyield stress (σb), rupture stress (σr) and Young's modulus of elasticity (E). The results showed that a good correlation was found between the sc and other properties; σb, σr and E. Also, the average values of sc, σb, σr and E were 0.017 N/mm, 1158.3Pa, 1485.9 Pa and 6.94 kPa respectively. | ||
