Abstract

The present work was carried out to investigate the effects gamma rays on phenolic content and antioxidant activity of common date variety in Kerman Province, Iran, namely, Mazafati .In the present study, the radiation processing of dates samples was carried out at dose levels of 0, 0.5, 1 and 2.5 kGy. The phenolic content was measured by the Folin–Ciocalteau method and the antioxidant activity by reducing-power assay, total antioxidant capacity and DPPH methods. The results of the effect of different doses of gamma radiation (0.5 and 1kGy ) on the dates shows that no significant effect on antioxidant and the amount of phenolic content was observed. Gamma irradiation of dates at 2.5 kGy increased antioxidant activity and total phenolic content. In summary, gamma irradiation(2.5 kGy) increased the total phenolic content, as well as enhancing the free radical-scavenging activity.
