中文摘要:

      镰刀菌毒素是产毒镰刀菌侵染粮食作物时产生的有毒有害次级代谢产物, 其污染威胁主粮安全和人民生命健康。近年来, 随着毒素研究的深入和检测技术的迭代更新, 风险监测过程中发现, 原型毒素可在加工过程、动植物及微生物体内通过化学或生物方式改变结构及生化属性, 而不能被常规检测识别, 称为修饰型毒素。修饰型毒素可以通过食物链传导, 在动物机体释放原型毒素。本文综述了粮食作物中修饰型镰刀菌毒素的修饰类型、污染自然发生及毒理学等研究进展, 以期为镰刀菌毒素污染风险的全面评估及防控策略的研发提供参考。

英文摘要:

      Fusarium toxins are toxic and harmful secondary metabolites produced by toxigenic Fusarium spp. during infection in grains. Contamination with Fusarium toxins threatens the safety of staple grains and animal health. In recent years, with the deepening of toxin research and the development of detection technologies, modified mycotoxins with changed chemical structures and biochemical properties have been detected. These modified mycotoxins are produced during processing, or through chemical or biological reactions in plants, animals or microorganisms, and could not be identified by conventional detection. Modified toxins can be transduced through the food chain and release free toxins after animal consumption. This article reviewed the recent research progress of modified Fusarium toxins, including the modification types, natural occurrence, toxicology, which would provide references for the comprehensive assessment of the contamination risk of Fusarium toxins in grains and control strategies development.
