In the recent years the way of thinking about human health necessarily passes by human food. Recent discoveries do not only concern about valuable biomolecules but also contaminants. Thus, the screening of substances in animal and vegetable matrices by analytical techniques is focused on the presence and absence of target substance. In both cases, the majority of these substances are present as traces or in very low levels. Contaminants could be naturally present in the food, inserted on it or even developed on it as a consequence of food processing or cooking. Pesticides, mycotoxins, dioxins, acrylamide, Sudan red, melamine and now 4(5)-methylimidazole can be, at present, be listed as some of the world big problems related to food contaminants and adulterants. With the development of liquid chromatography coupled to mass spectrometry (LC-MS-MS), in the last few decades, analysis of some food contaminants in trace levels trace become less laborious, more accurate and precise. The multiple approach of those techniques make possible to obtain many results in one single run. On the other hand, European Union (2002/657/EC) established regulations for analytical methods regarding mass spectrometry as detection tool, showing the importance of this technique in food quality control. The EU criteria uses identification points (IPs) that could be achieved basically with four product ions (including molecular ion) or reduced with the use of high resolution equipments. This kind of mass spectrometers made the IPs criteria more accessible, as the exact mass information is a differential tool. In view of this the aim of this review is to present the actual scenario for mass spectrometry analysis in a complex vegetable food matrix such as roasted coffee, with emphasis on needs and challenges regarding the LC-MS technique in order to meet and contribute to food safety standards in this complex matrix.
