  Wheat (Triticum aestivum) is one of the most important agricultural crops. Requirements, wheat must be produced free of hazardous contaminants. However, previous investigations showed that wheat could be contaminated by aflatoxins above the limits that may be critical for health. In this study, use of the high oxidising power of ozone achieved degradation of aflatoxin B1. Samples were subjected to ozonation at various ozone concentrations (20, 40ppm) and exposure time (5, 10, 15, 20 min). The reduction percentages of aflatoxin B1 in artificially contaminated wheat 10 μg/kg were 84.1 and 86.75% after exposures to 20 and 40 ppm ozone for 20min respectively, and 86.7 and 96.66 % with 20 μg/kg after exposures 20 and 40 ppm ozone for 20 min, respectively. The percentage of inhibition zone from Aspergillus flavus was 46.4 % to 87.8 % after ozonation using concentration 20 ppm for .. Read More»
