Ochratoxin A was produced, at concentrations of about 200 mg kg1 of dry beans (Phaseolus vulgaris L.) of each of five Brazilian commercial varieties. Both intact and decorticated kernels of the varieties Preto, Branco, Rosinha, Roxo and Carioca (22% moisture) were inoculated withAspergillus alutaceous and incubated at 25°C for 28 days. Results from thin-layer and column chromatography, mass, infrared, 1H-nuclear magnetic resonance and UV-spectrometry showed that 1) the common bean is a highly stimulatory substrate for the bioproduction of ochratoxin A and 2) the putative toxin extracted by the method of Soares & Rodriguez-Amaya was in fact ochratoxin A. Removal of the seed coat resulted in increased OTA production for all varieties, particularly for the Rosinha, Roxo and Carioca.
