Food quality control has become much more important during the last decade and demanded the development of robust, efficient, sensitive, and cost-effective analytical techniques. Capillary electrophoresis with capacitively coupled contactless conductivity detection (CE-C4D) is a powerful separation method based on the different migration time rate of components in the background electrolyte solution, and it is suitable for all charged ions. There is a large number of compound groups in food that can be determined by the CE-C4D method, such as amino acids, biogenic amines, fatty acids, food additives, sweeteners, and nutrients. This paper provides an overview of recent applications of the CE-C4D in food analysis over the last decade. General conclusions and future prospects of applicability of the CE-C4D method in food analysis are presented.

This article introduces capillary electrophoresis using capacitively coupled contactless conduction detector (CE-C4D) and several applications that were developed for food analysis in Vietnam. The target analyte groups include: oxalate, sweeteners (acesulfam potassium, aspartame, cyclamate, saccharine) and food preservation (citric, benzoic and sorbic acids). This study aims to develop simple, easy to operate analytical procedures that are suitable for quick analysis or screening in food analysis in field or at local laboratories. The obtained results were compared with those measured by conventional standards method (HPLC) and proved the high reliability of CE-C4D method.
