Advances in Lipid Capillary Electromigration Methods to Food Analysis Within the 2010s Decade

Capillary electrophoresis (CE) is a technique that may offer high-resolution separations in complex matrices with a short analysis time. It generally employs straightforward sample preparation protocols and requires low amounts of sample and reagents, which follows the green chemistry concept. This review presents several methods developed within the 2010s decade, aiming simpler and faster food analyses in the determination of lipids applying CE. It summarizes sample preparation protocols, background electrolyte, and instrumental conditions optimized in each method. Different CE modes and detection systems are discussed, as well as figures of merit of the developed analytical methods. Moreover, it approaches significant challenges involved with lipid assay by CE and opportunities for innovation in the lipid research.
