Abstract


Packaged strawberry of two cultivars grown in Egypt were submitted to ‎vibrational equipment. During test, the accelerations at three different ‎positions of the column of crates were measured. Vibrational energy ‎during transportation fruits was 1204 kJ/kg ((m/s 2)2.s/Hz) resulting ‎bruise 7, 7.3% for the two cultivars Festival and Fortuna, resp. Bruise ‎due to vibration stress occurred in 25 and 48.2% for Festival and ‎Fortuna cultivars, respectively. The degree of maturity of 80-85% to ‎less damage, where the proportion of the damage with the highest ‎vibratory energy (2094 kJ/kg), while 25%. Exposed strawberries placed ‎in the middle crate into the biggest damage where the percentage of ‎damage to 50% at the end of the storage period. ‎
