Abstract

Wheat (Triticum vulgare L.) samples were collected from different villages in three Centers of Minoufiya Governorate, Egypt during the period (2013-2014) and used immediately for Aflatoxin B₁ (AFB₁), moisture and fat content determination. AFB₁, moisture and fat content in samples were varied from 0.98 to 3.19 µg.kg-1, 13.57 to 16.11% and 1.39 to 1.89%, respectively. Samples with the higher AFB₁ concentration are the samples of higher moisture and fat content. Half of the tested wheat grains samples recorded AFB₁ concentration more than the maximum permissible limits for human consumption (2 μg/kg AFB₁). When all wheat samples were included in the statistical analysis, there was a positive significant (p≤ 0.05) relationship between moisture content (r²= 0.694), fat content (r²= 0.527) and AFB1 concentration. These correlations confirm that moisture content is mainly participate for the AFB₁ concentration of the tested wheat grain samples while fat content are partially participated. In conclusion, consumption of some wheat sampled storaged by traditional methods can pose a potential risk of development of various diseases in human and animals. Also, for the proper storage of wheat grain, environmental factors such as moisture content and temperature must be controlled.
