The influence of drop heights on apple's storage life was studied using Luochuan fushi apple as samples. The apples were dropped using the drop test system made by ourselves. The hardness and storage life of apples after drop in different drop heights were tested under below critical drop height. The data were analyzed with statistics method. The results showed that apple does not bruise under below critical; the storage life of apples is shortened after dropped; the storage life of apples decreases with drop height.
