Integrated process for ammonia inactivation of aflatoxin-contaminated corn and ethanol fermentation

A process is described for converting aflatoxin-contaminated corn to ethanol via combining ammonia inactivation with the liquefaction step of the ethanol fermentation process. Better ethanol yields were obtained when ammonia was added during liquefaction than when no ammonia was added. Aflatoxin B1 levels were reduced 80 to 85% by the process.
