In order to study the effect of nano-SiO₂ modified low density polyethylene (LDPE) film on Gonggan storage, the influences of unpacked, LDPE film and nano-SiO₂ LDPE film packaging treatments on postharvest quality of Gonggan were investigated. The results showed that both of the packing materials could improve the postharvest quality of Gonggan, and nano-SiO₂ LDPE film was better in slowing down the increase of the decay rate and weight loss ratio, and the decrease of firmness. Moreover, the nano-SiO₂ LDPE film was found to be better in inhibited the accumulation of malonaldehyde (MDA), and maintained higher content of total-soluble solids (TSS) and titratable acid (TA) content at the later period of storage. Furthermore, maintaining higher antioxidant capacity and hedonic scale of Gonggan fruits were also confirmed.
