“…The method allowed rapid monitoring of food quality with minimum sample pretreatment and low LOQs in the range of 2.3-7.3 mg/L. In addition, to minimize dilution of the dialysate, a new type of FGI was developed, in which the sample was transferred into the air, not to the gating solution [31]. A drop of the dialysate was forced from the delivery capillary into the empty injection space by the air pump and hydrodynamically injected into the separation capillary.…”

Development of new capillary electrophoresis (CE) methodology and instrumentation, as well as application of CE to solve new problems, remains an active research area because of the attractive features of CE compared to other separation techniques. In this review, we focus on the representative works about sample preconcentration, separation media or capillary coating development, detector construction, and multidimensional separation in CE, which are judiciously selected from the papers published in 2018-2020.

“…Besides, the current strict regulations require not only accurate but also sensitive, simple, and fast procedures that allow efficient, rapid, and easy evaluation of nutritional values. In this regard, Opekar et al developed a methodology based on CE separation coupled to C 4 D for the evaluation of majority cations present in unflavored yogurts after digestion with acid treatment (boiling 6 mol/L HCl) and dialysis purification in miniaturised mode [96]. The microdialysis unit was directly connected with the CE system through a flow-gating interface, simplifying the procedure.…”

This work presents a revision of the main applications of capillary electromigration methods in food analysis and Foodomics. Articles that were published during the period February 2019‐February 2021 are included. The work shows the multiple CE methods that have been developed and applied to analyze different types of molecules in foods. Namely, CE methods have been applied to analyze amino acids, biogenic amines, carbohydrates, chiral compounds, contaminants, DNAs, food additives, heterocyclic amines, lipids, secondary metabolites, peptides, pesticides, phenols, pigments, polyphenols, proteins, residues, toxins, vitamins, small organic and inorganic compounds, as well as other minor compounds. The last results on the use of CE for monitoring food interactions and food processing, including recent microchips developments and new applications of CE in Foodomics, are discussed too. The new procedures of CE to investigate food quality and safety, nutritional value, storage and bioactivity are also included in the present review work.
