Aflatoxins are of difuran cyclotoxins produced by Aspergillus flavus and Aspergillus parasiticus, and own good chemical stability, thermal stability, strong hepatotoxicity, carcinogenicity, teratogenicity and other toxicity to human body. Due to the low content of aflatoxins in food and the complex food matrix, these food samples contain a large number of carbohydrates, fats, proteins, food additives, etc., which have great interference to the accurate qualitative and quantitative detection of aflatoxins. Therefore, it is of great significance to explore new sample pretreatment techniques and establish rapid and practical detection methods for aflatoxins. This paper reviewed the application of aflatoxin pretreatment techniques (liquid phase extraction, solid phase extraction, ultrasonic microwave assisted extraction, immunoaffinity chromatography) and detection methods(thin-layer analysis, high performance liquid chromatography-mass spectrometry, enzyme-linked immunosorbent assay, immunochromatography, nucleic acid aptamer sensing) in the analysis of aflatoxins in food, prospected the development trends towards online combination, the integration of new technologies with traditional equipment, ease of operation, and low cost, providing reliable support for the development of mycotoxin detection.
