Effect of gamma irradiation doses and salting solutions (NaCl %) on the fumonisins (B1 &B2) of infected and row maize

Ahmed A. Aly, Khaled, M. Elmeleigy


The objectives of this investigation were to evaluate the effects and ability of gamma irradiation doses (4, 8 and 12 kGy) and salting solutions (7 %, 14% and 21% NaCl) to remove fumonisins (B1&B2) contaminated maize. Moreover, chemical and microbiological properties of maize affected by gamma irradiation doses were studied. The results indicated that: (i) there were not differences between non-irradiated and irradiated maize samples for its chemical composition; (ii)gamma rays had completely inactivated counts of total bacteria, molds and yeasts; (iii) a dose of 4, 8 and 12 kGy were sufficient for complete destruction of fumonisins infected maize; (iv) the fumonisins content in the row and deliberately infected maize decreased with the increasing concentration of  NaCl; and (v) the combination of gamma irradiation and NaCl solutions inhibited of fumonisins. It can be concluded that gamma irradiation and NaCl solutions can be used for detoxification of fumonisin-contaminated maize and improving its microbial loud.
