“…4B presents the results found for the determination of catechin in the cocoa matrix by the proposed procedure. As a further validation study and with the aim to prove the reliability of the proposed catechin sensor, the cocoa sample was also submitted to a previously validated electrophoretic method, 27 slightly modified, to estimate the flavonoid concentration. The analyses were performed by five-fold.…”

“…22 To date, the determination of catechin content in food samples was mostly carried out based on high-performance liquid chromatography-UV/uorescent detection (HPLC-UV/FL), gas chromatographymass spectrometry (GC-MS) and capillary electrophoresis-UV (CE-UV). [23][24][25][26][27] However, HPLC-DAD/FL, GC-MS or CE-DAD require complex separation and determination systems and long analysis times. Compared to the above methods, uorescence technology is highly efficient and easy to operate and it has become an effective method for routine analysis.…”

“…In the same line, the use of cyclodextrin-modified graphene quantum dots has been presented for the determination of polyphenols in dietary supplements in less than 13 min. This additive allowed to avoid the use of organic solvents or sur-factants in the BGE, improving the analytical features of the developed method [45].…”

This work presents a revision of the main applications of capillary electromigration (CE) methods in food analysis and Foodomics. Papers that were published during the period March 2021 to March 2023 are included. The work shows the multiple CE methods that have been developed and applied to analyze different types of molecules in foods and beverages. Namely, CE methods have been applied to analyze amino acids, biogenic amines, heterocyclic amines, peptides, proteins, phenols, polyphenols, pigments, lipids, carbohydrates, vitamins, DNAs, contaminants, toxins, pesticides, additives, residues, small organic and inorganic compounds, and other minor compounds. In addition, new CE procedures to perform chiral separation and for evaluating the effects of food processing as well as the last developments of microchip CE and new applications in Foodomics will be also discussed. The new procedures of CE to investigate food quality and safety, nutritional value, storage, and bioactivity are also included in the present review work.

The development and application of faster and more powerful analytical methodologies in Food Science is essential to face the demands from regulatory agencies, official laboratories, and consumers. In this field, capillary electrophoresis (CE) is nowadays a well‐established separation technique for food analysis that possesses exceptional properties related to high analysis speed and separation efficiencies combined with the small samples and reagent requirements. Moreover, it is a very versatile technique since different CE modes can be employed for a broad range of applications and separation challenges. In fact, CE should be considered as the first option when dealing with highly polar, charged, or chiral analytes. In the past two decades, a high amount of research work has been published, demonstrating the high potential of CE to analyze different food components in a broad variety of food matrices. The aim of this article is to provide an overview of the use of CE for food analysis including a summary of the characteristics of the CE modes and the main detectors mostly employed in this field. Besides, a wide view of the latest applications of CE in food analysis (2021–2023) is also provided, demonstrating the exceptional possibilities of this analytical technique.
