Abstract
The effects of gamma radiation on Mozafati date were evaluated in order to find microbial and chemical changes. For this purpose, the date samples were stored at different temperatures, 25°C (room temperature), 4°C (refrigerator) and -18°C (freezer) for a period of 6 months. At each temperature, 4 samples were considered as a control (unirradiated) and three others as irradiated with doses of 0.5, 1.0 and 2.5 kGy by the use of gamma irradiation. Every month, the samples, at each condition, were checked to detect the total microbial, mold and yeast contaminations. The same date samples were also analyzed to chemical and quality controls (sugar and moisture). Finally, the unirradiated samples were compared with the irradiated ones. It was concluded that the proper condition to decrease microbial contaminations and chemical changes, and to increase the shelf-life and stabilize quality of the Mazafati date is the dose rate of 0.5 kGy at 4°C temperature.
