Description
Two varieties of com grains namely, triple hybrid 310 and Giza 2 were used in this study. Samples were irradiated at different doses of gamma rays (0.0-10.0 kGy) and stored at room temperature for 12 months. Total molds on grains treated or not with 5% Na O Cl were reduced by increasing the applied radiation dose. Eight fungi were isolated and identified. Production of mycotoxins by fungi was detected. Asp. flavus produced B1 and B2 aflatoxin while Asp. fumigatus produced B1, B2, G 1 and G 2 aflatoxin, and Asp. Ochraceus produced ochratoxin A. The production by fungi was not prohibited up to the radiation dose level 3 kGy. The most sensitive spore to gamma rays was Asp. Ochraceus (D10 =0.42 kGy) while the most resistant was F. moniliforme (D10 = 1.0 kGy). 7 tabs
