Ammonia treatment of maize to control Aspergillus spp. and so prevent aflatoxin contamination

1992

Application of 0.5 percent ammonia to sample weight could inhibit multiplication of Aspergillus spp. In laboratory scale experiment, ammonia could control it and necessary concentration of ammonia depended on moisture content of samples. In farm scale experiment, ammonia on shelled maize worked better at higher moisture content. But effect of ammonia could not maintained long time if maize were not dried. Ammonia also could be obtained from urea solution mixed with soybean extract. Liquid ammonia worked better than that from urea at same concentration. Any ammonia treatment resulted in discoloration, however it was not so severe by ammonia from urea.
