Mechanical bruising to strawberry caused by vibrational equipment

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 1200 J/kg 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 (2100 J/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.
