Water activity influence on aflatoxin accumulation in corn

The influence of water activity on the production of B1, B2, G1 and G2 aflatoxins in corn has been examined. Viable corn kernels were conditioned at three water activity levels (0.87, 0.90 and 0.97) and inoculated with Aspergillus parasiticus at 30° C. Aflatoxin accumulation was determined at select...

Sumario:The influence of water activity on the production of B1, B2, G1 and G2 aflatoxins in corn has been examined. Viable corn kernels were conditioned at three water activity levels (0.87, 0.90 and 0.97) and inoculated with Aspergillus parasiticus at 30° C. Aflatoxin accumulation was determined at selected times by thin-layer chromatography. For the strain used total aflatoxin accumulation was greater at water activity 0.90 than at 0.87 and 0.97 for the incubation times studied. © 1988.
