Khalas, Shiashy and Rizez were selected for study. Freshly harvested date fruit
is prone to insect-pest infestation. It is, therefore, important to preserve
it properly to maintain fruit quality and enhance shelf life for human consumption.
The main aim of this study was to evaluate the effect of sunning as insect-pest
post-harvest control treatment on the quality characteristics and the antioxidants
of mature date fruit before and after sunning treatment. Dates treatments of
exposure to direct sun light for two days (48 h) significantly increased the
level of total phenolic compounds to more than 175% in all cultivars. The trend
was found in both assays for total phenolics and total flavonoids with the same
percentage in Khalas, Rizez than Shiashy. The FRAP value of fresh (control)
Shiashy (151.14 mg/100 g) was significantly higher than fresh Rizez and Khalas
dates (145.31 mg/100 g; 79.33 mg/100 g, respectively). Khalas cultivar showed
highest antiradical activity (240%) than Shiashy (178%) and Rizez (171%), respectively.
The results suggested that treatment of date fruit by exposing to direct sunlight
is an excellent substitute to chemical fumigation for safety and to maintain
quality characteristics for human consumption.]]>Abd El-Mohsen, M. and M.N. El-Din,199523229239Al-Farsi, M., C. Alasalvar, M. Al-Abid, K. Al-Shoaily, M. Al-Amry and F.
