Reduction in Aflatoxin Contamination of Rice by Milling Procedures.

Aflatoxins developed rapidly in rough rice inoculated with a toxin-producing strain of Aspergillus parasiticus and stored in a highly humid atmosphere (about 100% relative humidity) at 30 C. Maximum concentrations of the toxins were produced and accumulated after 15-33 days. More than 90% of the kernels were infected with A. Flavus spp. within 3 to 6 days. After 21 days in storage, an average of about 60-80% of the toxins by weight were found in the combined bran and polish fraction after milling. The bran and polish fraction contained the toxins in a concentration more than 10 times that of the milled kernels.
