Abstract:: Using Shangrao early pear as the experiment material，respiration intensity，vitamin C content and decay rate，the weightlessness rate of early pear during the storage were studied by the coating method.The results showed that N,O-carboxymethyl chitosan could significantly reduce respiration intensity，decay rate and keep the water content of pear during the storage，inhibit the decreasing of vitamin C content，thus maintain the fruit storage quality.The best treatment way of N,O-carboxymethyl chitosan was soaking in the 2.0% for 2 min.
