ABSTRACT
The effect of gamma irradiation on aflatoxin B1 levels and fungal infection were investigated in peanut samples, Tatu Vermelho cultivar. At a radiation dose of 10 KGy, growth of molds was completely inhibited. Doses of 15, 20, 25 and 30 KGy were sufficient for destruction of aflatoxin B1 by 55-74%. The results suggested that the decontamination of molds by irradiation, before production of aflatoxin B1, is the most acceptable method in the preservation of peanut.
RESUMO
O efeito da irradiação gama nos níveis de aflatoxina B1 e na infecção fúngica foram investigadas em amostras de amendoim, cultivar Tatu Vermelho. Dose de irradiação gama (60Co) de 10 KGy inibiu completamente o crescimento de fungos. Doses de 15, 20, 25 e 30 KGy foram suficientes para destruição de aflatoxina B1 de 55 a 74%. Pode-se concluir do presente trabalho, que a descontaminação de fungos por irradiação gama antes da produção de aflatoxina B1 é o método apropriado na preservação de amendoim.
