Advances in Sample Pretreatment of Aflatoxin Analysis
Aflatoxins in foods possess the carcinogenic,teratogenic and mutagenic feature,and other hazards.Efficient analysis of aflatoxin concentration is of great significance to ensure food safety and human health.Due to the low content of aflatoxins,complex sample matrix and various impurities,it is crucial to improve the sensitivity of sample pretreatment and detection method with the high selectivity,strong enrichment ability and preferable decontamination effect.In this paper,the advance in sample pretreatment of aflatoxin analysis in recent years was reviewed,including packed-fiber solid-phase extraction,liquid-phase extraction,immunoaffinity chromatography,ultrasonic and microwave-assisted extraction.Lastly,the prospect of its development in the field of food analysis was presented and significative reference for the development of food safety was provided.
