The effect of 1% chitosan with 0.03% zinc acetate or cerium acetate on the qualitative properties of harvested cherry tomato under ambient temperature was investigated. The results showed that chitosan maintained its crystal structure, but its crystallinity decreased in chitosan-zinc composite coating. While in chitosan- cerium composite coating, the chitosan crystal structure was changed. Two composite coating could inhibit the decrease of cherry tomato firmness and soluble solids, and suppress the increase of weight loss and malondialdehyde content. In addition, the respiratory rate was maintained lower level, and the activities of superoxide dismutase, peroxidase and catalase were maintained higher level during the cherry tomato storage time. Besides, after coating, more vitamin C and lycopene in cherry tomato were reserved compared with control sample.
