It was recognized in the early 1960s that a rapid screening method for aflatoxin was needed. Holaday first proposed the minicolumn chromatography method as a rapid screening method in 1968. Since that time, many improvements have been made in this method. The latest minicolumn method has a limit of detection of 5 μ g/kg and can be completed in 5‐7 min. The minicolumn technique has been expanded to include screening commodities other than peanuts for aflatoxin, as well as for other mycotoxins including ochratoxin, zearalenone and aflatoxin M 1.
