| Abstract:
Packaging fresh fruits in polymeric films of selective permeability has been found to delay their ripening and senescence process during storage by modified atmosphere. The present work was performed to investigate the potential of modified atmosphere storage of apples cv. "Pilafa Delicious" inside cold stores. The apples used for this study were seal-packaged inside low and medium density Polyethylene (PE) film sachets of different thickness and known permeability to oxygen and carbon dioxide. Atmospheres inside PE sachets varied from 1.5 to 18 % O2 and 3 to 12 % CO2 depending on film density and thickness. Modified atmosphere storage using PE film reduced weight loss and decay, but caused intense fermentation phenomena when CO2 concentrations exceeded certain limits. Atmospheres of type 1.5–3% O2 and 6–8% CO2 remarkably reduced flesh softening. This type of M.A. enables fruit to maintain good quality after a long-term storage of 7 months. | |
