Aflatoxin production by Aspergillus parasiticus on corn, soybean, and cottonseed in the absence or presence of added sodium phytate was examined. No variation in aflatoxin concentrations was found in raw, chemically sterilized, or autoclaved soybeans whereas a five-fold reduction in total aflatoxins was found in cottonseed after addition of 330 micrograms sodium phytate to 10 g of autoclaved material. However, phytate did not affect aflatoxin production on non-sterile cottonseeds, although in corn a slight inhibition was found. Extraction of raw soybeans with hexane allowed production of 20-fold more aflatoxins, but levels were still lower than those found on rice or corn. Part of this relative inhibition in soybeans may arise from a heat-unstable, polar solvent-soluble, dialyzable factor present in soybeans. Our results support the conclusion that phytate is not the factor in soy responsible for its relative resistance to aflatoxin formation.
研究了寄生曲霉在添加或不添加植酸钠的情况下，在玉米、大豆和棉籽上产生黄曲霉毒素的情况。在生大豆、化学灭菌大豆或高压灭菌大豆中，未发现黄曲霉毒素浓度有变化；而在10克高压灭菌的棉籽材料中添加330微克植酸钠后，总黄曲霉毒素含量降低了五倍。然而，植酸对未灭菌棉籽上黄曲霉毒素的产生没有影响，尽管在玉米中发现有轻微抑制作用。用己烷提取生大豆可使黄曲霉毒素的产量增加20倍，但含量仍低于在大米或玉米上发现的含量。大豆中这种相对抑制作用的部分原因可能是大豆中存在一种热不稳定、极性溶剂可溶、可透析的因子。我们的结果支持这样的结论，即植酸不是大豆中对黄曲霉毒素形成具有相对抗性的因素。
