Abstract: Using Lonicera edulis as experimental material, the property and affecting factors of coating antistaling agent and its application on preservation of Lonicera edulis were investigated.The formula of chitosany edible coating antistaling agent is 1% acetic acid used as dissolvent, 1%～2% chitosan and 0.35% sodium chloride used as form aid, and coating temperature is 40～ 60 ℃. The optimum technology parameters of preservation were obtained through single factor and orthogonal tests, which are as follows: 1.5% chitosan used as staling agent, 4% lactic acid calcium added as coalescing aid and peservation temperature 4 ℃.
