Abstract

PRADO, Guilherme et al. Effect of gamma irradiation on the inactivation of aflatoxin B1 and fungal flora in peanut. Braz. J. Microbiol. [online]. 2003, vol.34, suppl.1, pp.138-140. ISSN 1678-4405.  https://doi.org/10.1590/S1517-83822003000500047.

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.

Keywords : peanut; gamma irradiation; aflatoxin B1.
