Recent studies on postharvest behaviour of peaches.

Peach fruits suffer woolliness, internal browning and other physiological disorders or chilling injuries (CI) when stored at 0 or 2 deg C for up to 2 weeks. Intermittent warming (IW) for 1 day at 20 deg C every 6 days alleviated woolliness by promoting normal ripening. Ripening was measured as softening and colour development, the capacity to synthesize a suitable amount of ethylene and maintaining the ability to produce high enough levels of endopolygalacturonase, regardless of exopolygalacturonase activity. IW for 1 day at 15 deg C every 6 or 8 days for fruits stored at 0 deg C exacerbated CI; however this treatment alleviated scald. High CO2 and low O2 concentrations in modified atmosphere packaging (MAP) reduced CI, but ethanol and acetaldehyde accumulated in the bags. The use of polypropylene bags was beneficial only when peaches were stored at 0 deg C. IW combined with MAP did not improve results obtained with IW alone.
