| Abstract | ||
| The present study was undertaken at the postharvest laboratory,Horticulture Research Institute, Giza and development of horticulture, AinShamsUniversity. during 2002, 2003 and 2004 seasons to evaluate storability and maintain the physical and visual quality of sweet corn ears of Endeavor F1 hybrid were picked at 25 day after silking (the optimum harvest stage) using cleaning stretch film and polyolefin film wrapping films at 0 and 5ºC storage temperature at different storage periods. The main results showed that holding the ears at 5ºC storage temperature increased the weight loss percent, denting, decay and reduced the visual quality values compared to holding at 0ºC. Carbon dioxide percent inside the package was higher when ears were stored at 5ºC compared to 0ºC and when ears were wrapped with polyolefin film. Wrapping films reduced the weight loss percent of ears compared to unwrapping, the lowest values were by polyolefin film. In addition, wrapping with polyolefin film decreased kernel denting but the decay value was higher with polyolefin film compared to cleaning stretch film. Also, unwrapped ears had higher total sugar percent compared to ears wrapped with polyolefin film or cleaning stretch film. Cleaning stretch film, generally, gave best visual appearance during storage. Wrapping ears with polyolefin film maintained the sucrose percent higher than those of cleaning stretch film or check treatments. Sweet corn ears held at 0ºC had higher percent of non-reducing sugars compared to 5ºC. Storing ears at 0ºC maintained higher TSS compared to 5ºC. With prolonging the storage period, weight loss, decay, denting and discoloration for cut ends were increased. But, visual quality, TSS, total and non-reducing sugars were decreased. | ||
