Rapid and simple determination of aflatoxin M1 in milk in the low parts per 10(12) range.
A method for extracting aflatoxin M1 from milk is proposed in which the use of disposable Extrelut clean-up columns simplifies the analysis considerably in comparison with existing methods. The quantitative determination is based on one-dimensional thin-layer chromatography and fluorescence densitometric measurement. The detection limit is 5 ppt (parts per 10(12)) in milk and the recovery is 78 +/- 4% at a level of 50 ppt.
