摘　　要：真菌毒素是由特定真菌产生的次生代谢产物,在整个动物食物链中都能发现。农业和畜牧业中主要的真菌毒素有黄曲霉毒素B1、呕吐毒素、玉米赤霉烯酮、伏马毒素、赭曲霉毒素和T2毒素。霉菌毒素造成的经济损失和健康问题引起了人们对探索新的灭活和解毒方法的研究兴趣,如从被污染的谷物中去除霉菌毒素,降低动物胃肠道中此类霉菌毒素的生物利用度,或直接降解饲料中的霉菌毒素。在此基础上,开发和优化降解微生物/酶的吸附、化学处理和生物转化等方法。本文综述了近年来报告的脱毒技术和应用,对这种新型的解毒方法和发展趋势有一个清晰的认识,将有利于饲料和畜牧业,最大限度地提高消费者的安全和畜牧业及相关产业的利润。Mycotoxins are secondary metabolites produced by specific fungi and are found throughout the food chain of animal feed.The main mycotoxins in agriculture and animal husbandry are aflatoxin B1,vomiting toxin,zearalenone,fumarin,ochratoxin and T2 toxin.The economic losses and health problems caused by mycotoxin contamination have led to interest in exploring new methods of inactivation and detoxification,such as removing mycotoxins from contaminated grains,reducing the bioavailability of such mycotoxins in the animal gastrointestinal tract,or directly degrading mycotoxins in feed.On this basis,the methods of adsorption,chemical treatment and bioconversion of degrading microorganisms/enzymes were developed and optimized.This paper reviews the reported detoxification technologies and applications in recent years,and has a clear understanding of the new detoxification methods and development trends,which will be beneficial to feed and animal husbandry,maximizing consumer safety and profit of animal husbandry and related industries.
