PHYSIOLOGICAL STUDIES ON POMEGRANATE FRUITS AND SEEDS DURING COLD STORAGE.

This study was conducted during the two seasons of 2001 and 2002 on fruits of Manfaloti Pomegranate obtained from a private orchard in Assuit Govemorate. The first aim of this research is to study the effect of polyethylene film as a packaging liner to protect fruits duning storage at different cold temperatures. The second aim is to study some safe preserving materials on the keeping quality of Pomegranate seeds (as fresh cut) duning cold storage. Chemical and physical properties were studied. Lining boxes with polyethylene can be a successful method for minimizing weight loss % and keeping freshness of pomegranate fruits during storage and extended its storage life to 60 days at 0°C and 5°C. Concerning the storage of Pomegranate seeds, the storage life was 15 days at 0°C and 5°C. The best treatments for preserving Pomegranate seeds is the treatment by using citric add followed by treating the seeds with ascorbic acid.
