Abstract

Thirty bean samples of different brands were chosen in the Goiânia retail market to be analized by thin-layer chromatography in order to detect the possible presence of aflatoxins. Only one sample showed a very low concentration of aflatoxins B1 and G1. The level of contaminants was inferior to 2.5 ppb (the standard). The process was repeated by boiling the sample at 116ºC for 30 minutes under 0.7 kgf/cm2 of pressure and then analyzed once again. The same level of contaminants was found proving the insufficiency of the thermal combustion method.

KEY-WORDS: Micotoxin; food; Leguminoseae.
