Effects of Chitosan/TiO2 Composite Coating on Keeping-Fresh of Stauntonvine

The effects of Chitosan/Nano-TiO2 composite coating in extending postharvest life of stauntonvine and maintaining their qualities were investigated. Stauntonvine were treated by chitosan/nano-TiO2 composite coating and chitosan coating respectively. Changes in respiration rate, ascorbic acid content, titrable acidity, soluble total sugar were measured and compared. Compared with chitosan coating, the application of Chitosan/Nano-TiO2 composite coating could reduce the respiration rate and the loss of ascorbic acid, and also could increase the titrable acidity, soluble total sugar, and partially inhibited decay of fruit during storage.
