Effectiveness of hand sorting, flotation/washing, dehulling and combinations thereof on the decontamination of mycotoxin-contaminated white maize

摘要: Maize is one of the major staple foods Sub-Saharan Africa and consumed as whole or dehulled grain. In this region, where environmental conditions favour fungal growth mycotoxin production, majority population are subsistence consumers who, unfortunately, have little no access to testing their food. an attempt develop feasible reduction strategies in dietary exposure population, a three-factorial design experiment was conducted examine compare efficacy hand sorting, flotation, dehulling combinations thereof removing naturally occurring aflatoxins, fumonisins, nivalenol, deoxynivalenol alternariol shelled white maize. Regression analysis used determine significant (p < 0.05) process variables on removal mycotoxins from Results indicated that sorting had greatest effect removal, while flotation yielded least effect. particular left 6% aflatoxin B1 5% fumonisin B1. Based these results, maize grains being recommended last line defence against among consumers.
