Study on effect of chitosan film coating on mango storage

The article studies to use chitosan coating with effective microbe inhibiting treatment on mango preservation. The results show that the optimal formula of the preservative is 1.5% chitosan, 0.10% preservative, pH5.45. The preservative may keep retention period of mango smoothly up to more than 18 days when treated with it at room temperature (26~30℃) and make weight-loss be less than 35.2%. Meanwhile, the rate of unvarnished mango is 100%, the rigidity of mango decrease 13.7%. The quality of the mango can be retained and the good quality period can be prolonged.
