Abstract : Ammoniation pressures the best techniques to detoxify aflatoxin-contaminated grain. It considered as economically practicable for commercial applications. In the present study yellow corn was contaminated by aflatoxin using a strain of Aspergillus parasiticus to produce total aflatoxin 4000 µg/kg corn. Two procedures of ammoniation (in aqueous ammonia concentrations, 0.25, 0.5, 1, 1.5 and 2%) were adopted for aflatoxin destruction. The frist procedure was under atmospheric pressure at ambient temperature (AP/AT) for 24 hr. And the second procedure was under high pressure (2 bar) at high temperature (121°C) (HP/HT) for 15 min. Aflatoxin concentrations were determined by HPLC using fluorescence detector. The effect of HP/HT procedure was compared with the ammoniation procedure under AP/AT. The detoxification pattern of the two ammoniation procedures as well as the detoxification pattern of the different types of aflatoxins under the two procedures was studied
