摘要
赭曲霉素A(Ochratoxin A,OTA)是青霉菌属与曲霉菌属共同产生的具有 7 种结构的二级代谢产物,在小麦、玉米、大米及大麦等粮食中广泛存在.赭曲霉素A可致畸,具有肾毒性、神经毒性、免疫毒性等危害,可引起动物肾脏、肝脏损伤、坏死以及肠黏膜损坏.本文综述了粮食中赭曲霉素A的主要检验方法,重点分析与讨论了不同检验方法优缺点,以期为更加准确、高效、便捷的检测粮食中赭曲霉素A提供依据.
Abstract
Ochratoxin A is a secondary metabolite with seven structures produced by Penicillium and Aspergillus.It is widely found in wheat,corn,rice and barley.Ochratoxin A can cause teratogenicity,nephrotoxicity,neurotoxicity,immunotoxicity and other hazards,which can cause kidney,liver damage,necrosis and intestinal mucosal damage in animals.In this paper,the main detection methods of ochratoxin A in grain were reviewed,and the advantages and disadvantages of different detection methods were analyzed and discussed in order to provide a basis for more accurate,efficient and convenient detection of ochratoxin A in grain.
