Resumo
Descrevem-se técnicas de cromatografia em papel e em camada delgada para pesquisa e determinação de aflatoxina em alimentos para consumo humano e em rações para animais. Usando essas técnicas foram analisados 32 alimentos, dos quais 20 continham aflatoxina, e 130 rações das quais 104 estavam contaminadas, Além da farinha de amendoim e outros produtos de amendoim, a farinha de mandioca mostrou-se altamente contaminada com aflatoxina. Bissulfíto de sódio a 1: 10000 mostrou-se efetivo para evitar o desenvolvimento do Aspergillus flavus na farinha de amendoim.
