Shock tests on Golden Delicious apples from Victoria, Australia, were performed using a programmable shock tester. Bruise volumes were measured on apples undergoing durations of impact varying from 2 to 10 milliseconds. The same set of tests was repeated for the same batch of fruits stored for different periods, ranging from freshly purchased to stored for 3 weeks. It was found that the duration of impact had a significant effect on bruise volume, which was also affected by storage period, but to a lesser degree. Another experimental set-up for drop tests, using load cell sensors, was carried out on the same batch of apples. The purpose of these drop tests was to compare the results obtained from these direct tests with those from the shock tester. It was found that the bruise volumes from these 2 types of tests differed significantly with comparable drop heights. Both types of test were performed with drop heights ranging from 5 to 20 cm. It was concluded that some adjustment to the results fro
m the shock tester would be necessary before the data could simulate practical applications.
