Spores of Aspergillus flavus (UI, 81) inoculated into some local food materials were irradiated at 62.5, 125.0, 250.0 and 500.0 krad, and the effect on aflatoxin B1 production on subsequent incubation was measured. The results show that aflatoxin B1 production decreased with increasing gamma irradiation dose in soya bean, groundnut, palm juice, while paw paw mash showed a relatively high yield of aflatoxin at 125.0 krad as compared to other irradiation levels tested except for the control. Irradiation of soya bean and groundnut inoculated with spores of Aspergillus flavus at 500.0 krad (pre-irradiation incubation period of 2 h) inhibited aflatoxin B1 production. Analysis of variance showed that media, pre-irradiation incubation periods and irradiation levels affected the total amounts of aflatoxin produced.
将黄曲霉（UI，81）的孢子接种到一些当地食物原料中，分别用62.5、125.0、250.0和500.0千拉德的剂量进行辐照，并测定对后续培养过程中黄曲霉毒素B1产生量的影响。结果表明，在大豆、花生、棕榈汁中，黄曲霉毒素B1的产生量随γ辐照剂量的增加而降低，而与除对照外的其他测试辐照水平相比，番木瓜泥在125.0千拉德时黄曲霉毒素的产量相对较高。用500.0千拉德（辐照前培养2小时）辐照接种了黄曲霉孢子的大豆和花生，可抑制黄曲霉毒素B1的产生。方差分析表明，培养基、辐照前培养时间和辐照水平会影响黄曲霉毒素的总产量。
