Abstract |
Recently, special attention has been given to kiwifruits production in Egypt due to its great nutritive and economic values. This research aims to study the effect of packages on cooling capacity and quality of kiwifruits during different cold storage periods of 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165 and 180 days followed by three different exposure periods (10, 20 and 30 days) to the normal ambient air temperature. This research was carried out in Mansoura commercial refrigerator (Mansoura City – Dakahlia Governorate) during the product season of 2001. Cardboard boxes and polyethylene bags package were used to store kiwifruits at 4 °C and 90% air relative humidity and compared with the stored kiwifruits without package. The obtained data revealed that:
- The stored kiwifruits using cardboard box packages: It required cooling capacity of 140.71 Kcal/h. ton during 15 days of cold storage. As the cold storage period was elongated to be 180 days, it required cooling capacity of 73.49 Kcal/h. ton. All the fruits were kept fresh during the cold storage periods. During the exposure periods of 10, 20 and 30 days to the normal ambient air temperature, the fruits were decayed after 150, 105 and 75 days of cold storage respectively.
- The stored kiwifruits using polyethylene bag packages: It required cooling capacity of 138.47 Kcal/h.ton during 15 days of cold storage. As the cold storage period was elongated to be 180 days, it required cooling capacity of 73.38 Kcal/h.ton. All fruits were kept fresh during the studied cold storage periods and ambient storage of 10 days after all cold storage periods. During 20 and 30 days of ambient storage, the fruits seemed to be decayed after 165 and 105 days of cold storage respectively.
- The stored kiwifruits without package: It required cooling capacity of 139.61 Kcal/h.ton during 15 days of cold storage. As the cold storage period was elongated to be 180 days, it required cooling capacity of 73.40 Kcal/h.ton. All fruits were kept fresh during the studied cold storage periods. During 10, 20 and 30 days of ambient storage, the fruits seemed to be decayed after 105, 75 and 45 days respectively.
Finally, the stored kiwifruits using polyethylene bag packages achieved lower cooling capacity and higher fruit quality under both cold and ambient storage conditions. Also, it enlarges the producer profit through extending the season for which kiwifruits are available in the market.
