Mechanical properties of three sweet Cherries varieties (Greece, Spain and German sweet cherries) and one sour cherry variety (German sour cherry) fruits were studied by using Instron Universal Testing Machine model 4301. The effects of varieties and storage at different temperatures for Cherries fruits on physico-mechanical properties were studied by using the flat plate compression test.. The maximum compression force for cherry fruit is the most suitable single mechanical parameter that can be used to classify the batches unambiguously and to distinguish between varieties. The maximum compression force varied from 26.97 N (Spanish sweet cherry) to 16.94 N (Werder German sweet cherry). The Young’s modulus ranged from 0.0315 MPa (Spanish sweet cherry) to 0.0197 MPa (Werder German sweet cherry). Maximum force, elastic modulus values and energy for all cherry fruits were decreased in the non chilled condition and with increasing storage time. The effect of the heat treatment on mechanical properties of cherries fruits was studied also.
