Abstract:Cherries are rich in nutrients，but easy to deteriorate，of which oxidative decay is one of the main reasons. This paper explored the role of bamboo leaf antioxidant（AOB）on cherry preservation. Konjac glucomannannone（KGM），chitosan（CTS），and citric acid（CA）were used as film-forming materials，to which bamboo leaf antioxidants were added.Then，the KTC（KGM/CTS/CA）/AOB activate packaging film was made by the solvent casting method.The efficacy of this packaging film in cherry preservation was evaluated by determining the changes in hardness，decay rate，anthocyanin content，and color difference of cherries after wrapping.The results showed that the hardness of cherries wrapped with KTC/AOB2（AOB concentration was 0.2%)active packaging film was 1.32 N/cm2 on the 6th day of storage，which was the lowest decrease compared with the polyethylene cling film group and the blank group，while the decay rate was only 37.1% of the blank group.Moreover，the anthocyanin content of cherries treated with KTC/AOB2 active packaging film was decreased by 27.71% compared with the blank group. In conclusion，KTC/AOB activate packaging film added with AOB was effective in cherry preservation.
