Grain Preservatives: Effect on Aflatoxin and Ochratoxin Production.

E. E. Vandegraft, C. W. Hesseltine, and O. L. Shotwell. Copyright 1975 by the American Association of Cereal Chemists, Inc. 

Corn was treated with either 2% ammonia or 1% propionic acid. Both ammonia and propionic acid significantly reduced mold growth and subsequent aflatoxin and ochratoxin formation. Growth and the formation of mycotoxins were inhibited more by propionic acid than by ammonia. Both ammonia and propionic acid remained effective in inhibiting mold growth and aflatoxin production and in preventing ochratoxin production when treated corn stood as long as 19 to 29 weeks, respectively, before inoculation.
