Aflatoxin production by Aspergillus Flavus on irradiated and non-irradiated stored egyptian bread

Aflatoxins production by Aspergillus Flavus isolate on several types of egyptian bread samples through a period of 45 days at different temperatures reveled that there was detectable fungal growth but no aflatoxins were produced at 5±1 degree or 37 degree. At 25 degree or 30 degree aflatoxin were produced after 5-6 days on the different bread types. Gamma irradiation of kaiser bread, previously inoculated with Aspergillus Flavus, reduced the amount of aflatoxins produced on subsequent storage for 8 weeks at 26±1 degree. The 5 KGy dose eliminated fungal growth and aflatoxin production. 4 tab
