[Method] Silverdoped nano-TiO2 preservative film was prepared, to investigate its preservation effects on Nanfeng citrus ripe fruits under novel preservation conditions and detect the influences of nano-composite coating on physiological quality indicators of Nanfeng citrus ripe fruits. [ Result ] Compared with the control, applying nano-compesite coating preservation technology could prevent fruit corruption and water loss and delay the rapid reductioh in contents of citric acid and Vc, without adverse influences on fruit quality. [ Conclusion] Silver-doped nano-TiO2 composite coating can be promoted and applied in frozen storage and preservation practices of Nanfeng citrus.展开更多

Three agent samples were characterized by X-ray diffraction （XRD） analysis to investigate the crystal structure, which confirmed a synergistic antibacterial effect. The antibacterial and preservative effects of silver-doped titanium dioxide coating film on Nanfeng citrus were investigated preliminarily. Nutritional indicators of ripe Nanfeng citrus before and after preservation were detected to investigate the preservative properties of silver-doped titanium dioxide coating film and compare the effects of different components of composite coating film. The results showed that Ag＋/TiO2 composite coating film exhibited high antibacterial and preservative effects on Nanfeng citrus under visible light illumination condition.展开更多
