Controlling aflatoxin contamination in maize stored under tropical conditions.

The effectiveness of a prototype in-store drying system in controlling aflatoxin contamination in maize was studied and the energy consumption of the system was determined. Tests were done using air with a defined relative humidity and temp. Results showed that to limit aflatoxin production, high moisture maize should be dried to 18 or 19% moisture content (wet basis) within 2 d and continuously dried to 14% within 14 d. To decrease moisture content from 19 to 12-13% using an airflow rate of 3.6-4.6 m3/min per m3 of maize, required an electrical energy consumption of 0.46-0.9 MJ/kg water evaporated or 16-27 baht/t of maize.
