Research Progress on the Detection Method of Ochratoxin A in Grain
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.
