Mechanical damages to fruits and vegetables are mostly induced during harvest and postharvest stages. One of the sources of postharvest mechanical damage is fruit and vegetable traortation. During fruit traortation, mechanical damages are generated by vibration, which is due to interaction of the road and truck’s suspension system. Severity of fruit damages during vibration depends on characteristics of vibration (frequency, acceleration and duration of vibration), fruit (fruit vibratory characteristics), traort type (specification of vehicle suspension system), road conditions, vehicle speed, fruit packaging type and position of fruit packages in the truck. Apple is an important product in our country and has a high production volume. Fruits and vegetable are exposed to mechanical damages due to unsuitable storing, packaging and traorting. To study the effect of packaging type on the damages caused by vibration, in this study, a vibratory table was designed and developed for the tests. The design of the system was based on rotary unbalanced masses. The vibratory table consisted of two parts. The first part is the suspension system which includes upper and lower springs and a fixed frame; the second part includes the vibrating table and a movable frame, and an eccentric mechanism which is installed on this part. The eccentric mechanism includes masses that are connected to rotary axes which rotate by a belt and pulley system. In this study, the effects of vibration frequencies (9 and 13 Hz), vibration during (30 and 60 min) and packaging type (net-foam, shredded paper and tray pack), and position of each apple row in the box on the apple bruising, using a factorial experiment in a completely randomized design with three replications, were investigated. The degree of damage on each apple was defined by a relative bruise index (RBI). The index is defined as the ratio of total bruise area on each apple to surface area of the same fruit. The effect of vibration frequency, vibration during, packaging type and position of fruit row in the box on RBI was significant ( P 0/05). The lowest RBI was obtained at frequency of 13 Hz and vibration duration of 30 minutes for the net-foam packaging; and the highest was obtain at frequency of 9 Hz and vibration duration of 60 minutes for the tray packaging. After vibration test, in order to study the vibration effects on the flesh strength؛ penetration tests on the whole fruit and compression tests on cylindrical samples of apples were conducted. The cubic equation of Henry and et al. (2000) was fitted to the force-deformation of the compression tests. The results showed that the effect of vibration characteristics (vibration frequency and duration), as well as the effect of packaging type and location (row) of apples in the box on the coefficients of a and c of the Henry’s model was not significant. However, the effect of frequency on the b coefficient was significant ( P 0.05) and the values of this coefficient at frequency of 9 Hz was significantly higher than 13 Hz. The effect of vibration frequency and duration on the penetration force of the apple flesh was significant ( P 0.01) and, the flesh strength was lowest at frequency of 13 Hz and duration of 60 minutes. The effect of frequency, vibration duration and type of packaging on the apple flesh fracture stress was significant. Increasing the frequency and duration of vibration caused a reduction in the fracture strength of apple flesh (failure point). Therefor, the vibration could have surface effect as bruising as well as bulk effect as reduction in flesh strength.
