Abstract :This study compared the postharvest quality of Hicaznar pomegranate fruit unpackaged and packaged with 5-kg or 12-kg bags of two different modified atmosphere packaging insert ignore into journalissuearticles values(MAP); materials insert ignore into journalissuearticles values(X5, X12, L5, and L12); during 6 months of storage at 6 °C. The fruits were also evaluated during a simulated shelf life period at 20 °C for 7 days after each cold storage period. The MAP bags significantly reduced the loss of titratable acidity and ascorbic acid content and retarded husk discoloration of the fruit during cold storage and the shelf life period. The incidence of fungal decay was lower in fruit packaged with MAP bags than unpackaged fruit. X5 and X12 MAP bags were more effective in reducing weight loss and husk scald than L5 and L12 MAP bags. X5 and X12 MAP bags maintained initial red aril color intensity and antioxidant properties of Hicaznar pomegranates throughout cold storage and the shelf life period. Unpackaged control fruit remained marketable for only 4 months at 6 °C plus shelf life period, while packaged fruit maintained visual quality for up to 6 months at 6 °C plus shelf life period.
