A method based on matrix solid phase dispersion extraction was applied to determine aflatoxins B(1), B(2), G(1), and G(2) from tigernuts and tigernut beverages. Recoveries of each aflatoxin from tigernut (spiked at 10 microg/kg level) and from tigernut beverages (spiked at 10 microg/L level) ranged from 72.3 to 82.1% and from 74.0 to 86.3%, respectively. The limits of quantification ranged from 0.21 to 1.49 microg/kg (for tigernuts) and from 0.13 to 0.57 microg/L (for tigernut beverages) studied using liquid chromatography with fluorescence detection. The proposed extraction method followed by liquid chromatography-fluorescence detection determination was applied to 37 and 25 samples of tigernuts and tigernut beverages, respectively, 3 positives being found in each category.
