Abstract
Aflatoxin production in rough rice (Oryza sativa), inoculated with Aspergillus flavus with an initial moisture content of 18 and 21%, respectively, was determined 3 times during a 20 day period. The range of aflatoxin concentrations after 20 days storage was 2430-10,643 .mu.g/kg B1 and 205-737 .mu.g/kg B2. Production of aflatoxin was higher at 21% moisture than at 18%, and more aflatoxin was produced at 30.degree. C than at 25.degree. C. Inoculum density was also important, with higher initial spore concentration yielding higher amounts of aflatoxin.
