Abstract
Abstract The Food Authorities are intensifying their efforts to assess the risks to human health from the exposure to (natural and anthropogenic) food contaminants. Therefore, regular surveillance studies are required to monitor the increasing number of toxicant residues in food. In this sense, an essential component is the development of new analytical approaches to reduce sample manipulation time and analysis costs without compromising the reliability of the results. This chapter will assess the prospects of the different ambient ionization techniques such as the direct analysis in real time (DART), desorption atmospheric pressure chemical ionization (DAPCI), low-temperature plasma ionization (LTP), and atmospheric solids analysis probe (ASAP) coupled to various types of MS analyzers for both target and nontarget analysis of complex food matrices. The prospects of these techniques as a simple, high-throughput tool for qualitative confirmation of chemical identity; metabolomic fingerprinting/profiling; and quantification of food components are presented and discussed.
