Abstract

Naturally contaminated corn containing 450 and 54 ppb aflatoxins Bi and B2, respectively was treated with Ca(OH)2 for making tortillas. The cleaned corn and tortillas were analyzed for aflatoxins B1 and B2 by high performance liquid chromatography (HPLC) and confirmed by thin layer chromatography (TLC). The average concentrations of aflatoxins B1 and B2 in the final products (tortillas) were only 40% and 28% lower than that in starting materials (corn kernels), respectively. Aflatoxins G1 and G2 were not detected in either corn or tortilla samples.
