They are one of the contaminants most common in food and feed, with high toxicity and carcinogenicity. Aflatoxins usually enter animal body together with feed and then enter human body by food chain, thereby seriously threatening human health. In recent years, the degradation of aflatoxins has become a hot research topic. This study overviewed the characteristics and detoxification ways of aflatoxins, specifically for the advances in biodegradation and degradation products of aflatoxins.展开更多

In 2007 deoxynivalenol was found up to 0.27 mg/kg in 2 of 18 samples of winter spelt kernels from organic farms. Also in 3 samples T-2 toxin was found in amount below 0.075 mg/kg. Aflatoxins and ochratoxin A were not found in kernels. Among nine of the examined samples of winter spelt in 2008, DON was identified in all samples （up to 0.31 mg/kg）, while T-2 toxin, aflatoxins and OTA were not found. Among twenty of the examined cultivars of winter spelt, deoxynivalenol was identified in 6 samples （up to 0.3 mg/kg）, T-2 toxin was identified in one sample in very low amount （below 75 μg/kg） while aflatoxins and ochratoxin A were not found. Deoxynivalenol was found in following winter spelt cultivars： T. spelta L. album, T. spelta BG, T. spelta BG 1166, T. spelta, Schwabenspelz and Franckenkorn. T-2 toxin was identified in T. spelta L. album BG 31. Among 13 products from spelt, DON was detected in 1 sample, OTA in 1 sample and zearalenone in 1 sample, T-2 toxins and aflatoxins were not found.展开更多
