Abstract
Solvent systems used to extract aflatoxins from groundnuts also extract measurable amounts of other compounds such as oils, fats, sugars and protein, and the vol. of these causes error in measuring the proportion of solvent solution analysed for aflatoxin. Also, as cleanup procedures for some methods are inadequate, the volume of some of these extracted compounds also causes error in measuring the proportion of the extracted aflatoxin placed on thin layer chromatography (TLC) plates. Studies reported showed that these 2 errors cause underestimation of aflatoxin concs. by approx. 11, 14 and 5% for the CB method, the AMS modified version of the BF method generally used for new groundnuts, and a water slurry method, respectively. The correction specified by the CB method for fats in the extraction solvent reduces the approximate error for the CB method from 11 to 1%.
