ABSTRACT

Apple fruits are subjected to different loading from harvesting to supermarket shelf. Bruising has been attracted by many researchers as one of the most important damage criterian. In the present research, the effects of some factors such as counter-face material, drop height and linear velocity of apples (conveyor speed) were investigated. Influence of these factors on bruising of "Golden Delicious" variety was analyzed by a completely randomized design (CRD) with factorial test at three level of drop height (10, 20 and 30 cm), conveyor speed (0.05, 0.1 and 0.15 ms-1) and four counter-face materials (wooden, steel, plastic and cardboard). Tests were conducted at three replications with 108 treatments. Analysis of variance results showed that the effects of drop height and counter-face material on bruising area at 1% level was significant while bruising volume only affected by contact surface material (P
