Abstract
The effects of a novel nano-ZnO coated PVC film on physicochemical quality and microbiological changes of fresh-cut ‘Fuji’ apple were evaluated. Fruit decay were efficiently reduced in nano-packing samples. The content of ascorbic acid and total phenolic dropped to 0.2 g•kg-1, 1.2 g•kg-1 in nano-packing samples and 0.02 g•kg-1, 0.6 g•kg-1 in control on day 12. In addition, the nano-ZnO coated PVC film not only inhibited the growth of total aerobic psychrophilic microorganisms, the count of which did not exceed 5 log cfu g−1 FW, but also suppressed the increasing of yeast and mould, the maximum growth of which reached only 3.6 log cfu g−1 in the nano-packing but 6 log cfu g−1 in control.
