Abstract

Taking 'Lvhua 9' peaches as material,the effects of 2 g/100mL chitosan,hot water(50℃,20 min)and combination of chitosan and hot water treatments on the quality of cold stored peaches were studied.The results showed that all treatments were able to relieve the injure of peaches,decreased the respiration rate of the peaches.The firmness and the incidence of decay were decreased(P0.05).The change of soluble solids content was not obviously(P0.05).Among the three treatments,the third one showed significantly higher inhibitory effect than the former two.Combination of 2 g/100mL chitosan and hot water treatments could effectively extend the shelf-life of 'Lvhua 9' peaches.
