Abstract
AbstractIn food analysis, conventional one‐dimensional liquid chromatography methods sometimes lack sufficient separation power due to the complexity and heterogeneity of the analyzed matrices. Therefore, the use of two‐dimensional liquid chromatography (2D‐LC) turns out to be a powerful tool to consider, especially when coupled to mass spectrometry (MS). This review presents the most remarkable 2D‐LC–MS food applications reported in the last 10 years, including a critical discussion of the multiple approaches, modulation strategies as well as the importance of the optimization of the different analytical aspects that will condition the 2D‐LC–MS performance. The presence of contaminants in food (food safety), the food quality, and authenticity or the relationship between the beneficial effects of food and human health are some of the fields in which most of the 2D‐LC–MS applications are mainly focused. Both heart‐cutting and comprehensive applications are described and discussed in this review, highlighting the potential of 2D‐LC–MS for the analysis of such complex samples.
