Abstract：This experiment studies in the changes of the relations among moisture content, temperature, growth of fungus and major hazard fungaltoxin in the storage of grain in Foshan. Through the experimental data, we set up an early prediction of quality and trend of content in hazard fungaltoxin of storing grain. Adjusted the moisture content of samples to 12.0%, 12.8%, 13.6%, 14.4%, 15.2%, then put the samples respectively into constant temperature incubator at 15℃, 20℃, 25℃, 30℃, 35℃, 40℃for 140 days. Meanwhile, took a sample to test the growth of fungus and major hazard fungaltoxin. The results showed that the grain was suit for a long-term storage while the moisture content was either 12.0% or 12.8%. As the moisture content was 13.6%, the grain stored for 49 days was easily infected fungal above 35℃. The fungus were detected while the moisture content was 15.2% in grain stored for 21 days at 6 temperature gradient. Morever, the content of hazard fungaltoxin exceeded badly. When the temperature range from 15℃to 40℃, the growth of fungal was proportional to the increasing temperature.
