The plum fruits (cv. Fraiar) were packaged with polyvinyl chloride resin (PVC) film and then stored at 0°C for 60 days, the results showed that modified atmosphere packaging (MAP) delayed the fruit softening, suppressed the increase of the soluble solid and anthocyanin content and browning degree, decreased the activity of polyphenolic oxidase (PPO) and content of phenolics substance and suppressed the accumulation of malondialdehyde (MDA) and production of superoxide radical (O2-), but had less effect on the superoxide dismutase (SOD) activity. Thus, it suggested that the MAP inhibiting plum fruits from softening and browning, closely correlated with the regulation on phenolics metabolism and membrane lipid peroxidation.
