Mycotoxins are considered one of the most dangerous agricultural and food contaminants.

Abstract

Mycotoxins are considered one of the most dangerous agricultural and food contaminants. They are toxic and the development of rapid and sensitive analytical methods to detect and quantify them is a very important issue in the context of food safety and animal/human health. The need to detect mycotoxins at trace levels and to simultaneously analyze many dierent mycotoxin types became mandatory to protect public health. In fact, European Commission regulations specified both their limits in foodstus and ocial sample preparation protocols in addition to analytical methods to verify their presence. Capillary Electrophoresis (CE) includes dierent separation modes, allowing many versatile applications in food analysis and safety. In the context of mycotoxins, recent advances to improve CE sensitivity, particularly pre-concentration techniques or miniaturized systems, deserve remarkable attention, as they provide an interesting approach in the analysis of such contaminants in complex food matrices. This review summarizes the applications of CE combined with dierent pre-concentration approaches, which have been proposed in the literature (mainly) in the last ten years. A section is also dedicated to recent microchip–CE devices since they represent the most promising CE mode for this application.
