Effet de différents facteurs (y compris l'irradiation gamma) sur la croissance et la production d'aflatoxines par l'Aspergillus flavus dans les graines de sésame.

Résumé

Sesame seeds were inoculated with a spore suspension of an aflatoxigenic isolate of A. flavus. The effect of different moisture content levels on total A. flavus count and on chemical quality attributes of inoculated sesame seeds was studied. The minimum moisture content of sesame seeds required for aflatoxin production was 10%. There was no aflatoxin production at 15 or at 40 °C, and maximum production at 30 °C. The highest production of aflatoxin was observed after 15 days of incubation. Irradiation decreased aflatoxin production in the seeds and the decrease was proportional to the irradiation dose.
