Two lots of aflatoxin-contaminated maize (527 p.p.b. and 3317 p.p.b.) were used to determine if a physical difference exists between aflatoxin-contaminated and aflatoxin-free maize. The 2 lots were segregated into buoyant and nonbuoyant portions b...

It involves extraction of grain with methanol and then thin-layer chromatography. The presence of aflatoxins B1, B2, G1 and G2 is indicated by a blue fluorescent spot.
