    Abstract:

    In this study,the effects of caboxymethyl chitosan(CMC) coating on the crisp quality of Shanghaimi Pears during 60 days of storage at 4 ℃ were studied.The results showed that the firmness of carboxymethyl chitosan-coated pears reached 1.13 times than that of the control pears after 60 days of cold storage(p<0.05).This is mainly due to carboxymethyl chitosan coating repressed the increasing activities of cell wall hydrolytic enzymes(including pectinesterase,polygalacturonase and cellulase),then reducing degradation changes in such cell wall materials as pectin,hemicellulose and cellulose,thereby delaying soft changes in Shanghaimi pears during cold storage.
