Abstract: In order to study the effects of chitosan-plant extracts composite coating on the fresh-keeping effects of cherry tomatoes, the composite film solution prepared by chitosan and different concentrations of clove/lotus leaf extracts was used for coating treatments, and the changes of hardness, weight loss rates, decay rates and nutritional components of cherry tomatoes during cold storage at 4 ℃ were investigated. The results showed that the fresh-keeping effects of cherry tomatoes were significantly improved after chitosan-plant extracts composite coating treatments, and the fruits color and freshness were well maintained. The hardness of 10 g/L chitosan-clove（10 g/L） extract treated fruits was the highest with a value of 220.8 g, the fruits decay rate was 10.00 percentage points lower,and the weight loss rate was 0.06 percentage points lower compared with blank control group, and the effects in inhibiting the loss of soluble solids, titratable acid, VC and other nutrients loss were the best compared with other treatments groups. This study provided a theoretical basis for developing novel biological preservatives for fruits and vegetables.
