fruits at 12◦C caused slight chilling injury (CI) symptoms on the fruit peel, expressed as red spots around the lenticels (lenticel spotting). A modified atmosphere
(5% CO2 and 10% O2) was created in 4-kg film-lined cartons by using microperforated polyethylene (PE) or Xtend film (XF). For ‘Keitt’ fruit, a similar atmosphere was also applied using controlled atmosphere chambers. After 3 weeks of storage at 12◦C plus 1 week at 20◦C, both modified and controlled atmosphere treatments were effective in reducing CI. The most effective reduction was found in fruits that were packed in the XF film. A second
advantage of using XF film was the reduction in the level of sap inside the package due to the lower relative humidity in the XF film (90%) compared with that of PE packaging (99%).
