Intermittent warming during cold storage of peaches packed in perforated polypropylene.

Peaches (cv. Paraguayo), harvested at the firm-breaker stage from an orchard in Italy, were sealed in perforated polypropylene bags (PPP) or placed in plastic boxes and stored at 0.5 deg C for 3 weeks. Some fruits were exposed to intermittent warming (IW; 20 deg for 1 day, applied twice every 6 days). After storage, some fruits were allowed to ripen for 3 days at 20 deg . PPP and PPP + IW maintained fruit quality and prevented chilling injuries. PPP fruits required a post-storage ripening period. IW slightly increased senescence, but shelf-life was extended and fruits had a good colour and taste. Fruits stored at 0.5 deg did not exhibit much evolution of ethylene, but produced ethylene when exposed to IW treatments and when placed at 20 deg for post-storage ripening.
