Ocorrência de aflatoxinas em feijões comercializados no mercado varejista de Goiânia-Go. Pesquisa Agropecuária Tropical, Goiânia, v. 32, n. 2, p. 109-114, jul./dez. 2002. Disponível em: <https://www.revistas.ufg.br/pat/article/view/2421>.1517-6398http://repositorio.bc.ufg.br/handle/ri/13047Thirty 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 inferi-or 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.porAcesso AbertoMicotoxinaAlimentoLeguminoseaeMicotoxinFoodArtigo
