黄曲霉毒素是某些黄曲霉菌和寄生性曲霉菌所产生的肝毒性代谢物。现已证实,像花生、棉籽、小麦、大米、大麦、椰子、玉米、干豌豆、燕麦、甜薯、小米和木薯等农作物均能被黄曲霉菌寄生产生黄曲霉毒素。由于大豆中含有丰富的蛋白质,是人和家禽的最佳营养品,能否被黄曲霉毒素污染的问题甚为重要。关于寄生性曲霉菌在大豆上产生黄曲霉毒素的报道很少,并且是有争议的。Shotwell等在一次现场调查中发现,866份样品中50%有被黄曲霉菌污染,但毒素污染率仅0.8%。Chang等虽然在发霉的大豆上分离出能产生黄曲霉毒素的NRRL 2999菌株,但未检出毒素。可是Davis等在Bragg变种大豆上
Aflatoxins are hepatotoxic metabolites produced by certain Aspergillus flavus and Aspergillus parasiticus. It has been confirmed that crops such as peanut, cottonseed, wheat, rice, barley, coconut, corn, dried peas, oats, sweet potatoes, millet and cassava can all be aflatoxin-parasitized by Aspergillus flavus. As soybean is rich in protein, is the best nutrition for humans and poultry, the issue of whether it is contaminated with aflatoxin is very important. There have been few reports of parasitic Aspergillus producing aflatoxins in soybeans and it is controversial. In a field survey, Shotwell et al. Found that 50% of 866 samples were contaminated with Aspergillus flavus, but the toxin contamination rate was only 0.8%. Although Chang et al. Isolated aflatoxin-producing NRRL 2999 strains on moldy soybeans, no toxins were detected. But Davis et al on the Bragg variant soybean
