For each procedure, 18 samples were prepared involving dry comminuting/homogenization or dry roughly comminuting followed by the preparation of a aqueous slurry. Ten analytical samples were withdrawn from each sample/procedure and analyzed by thin layer chromatography. The coefficient of variation (CV%) among each set of 10 analytical samples was assumed to be associated with the sample preparation procedure. The procedure that made use of a subsample mill and preparation of a subsample slurry, showed lower variability (CV%) among the analytical subsamples.1409-1495porsample preparationaflatoxinvariabilityArtigo10.1590/S0100-40422010000700012S0100-40422010000700012Acesso abertoS0100-40422010000700012.pdf0000-0001-5478-4996
