Short and medium‐chain fatty acids (SMCFAs) are known as essential metabolites found in gut microbiota that function as modulators in the development and progression of many inflammatory conditions as well as in the regulation of cell metabolism. Currently, there are few simple and low‐cost analytical methods available for the determination of SMCFA. This report focuses on SMCFA analysis utilizing CE with indirect photometric detection (CE‐IPD). A ribonucleotide electrolyte, 5’‐adenosine mono‐phosphate (5’‐AMP), is investigated as an IPD reagent due to its high molar absorptivity and dynamic reserve compatible with separation and detection of SMCFA. The operating parameters like the composition of organic solvent, millimolar concentrations of the complexing agent (alpha‐cyclodextrin), 5’‐AMP and non‐absorbing electrolyte (boric acid), as well as the applied voltage, are optimized for resolution, efficiency, and signal‐to‐noise ratio. A baseline resolution of all nine SMCFAs is achieved in less than 15 min. Additionally, the developed CE‐IPD method shows promising potential to identifying SMCFA in rat fecal supernatant. The presented analytical assay is simple, economical, and has considerably good repeatability. The intraday and interday RSD of less than 1 and 2% for relative migration time, as well as less than 14 and 15% for peak area, respectively, were obtained for SMCFA in fecal solution.

“…The large number of applications of CE-MS has demonstrated its suitability for several -omics approaches [22,23]. In the recent bibliography, novel CE methods were applied to the analysis of wines, among other different fruit juices and beverages [39][40][41]. However, its use in the field of oenology for metabolomics applications to wine authentication is limited to a few studies.…”

“…CE has also given impressive results for the analysis of organic and inorganic anions . A procedure for the CE determination of lactic, malic, tartaric, and citric acids in fruits, juices, nectars, wines, and beer was developed using 3‐nitrobenzoic acid as a light‐absorbing component of the running buffer and indirect photometric detection . CE was also used to determine the concentrations of nitrate, nitrite, and oxalate in two vegetables that are popular at Black Sea coast, namely kale ( B. oleracea var.…”

Recent advances in the application of capillary electromigration methods for food analysis and Foodomics

et al. 2013

View full text Add to dashboard Cite

In this work, the analysis of foods and food components using capillary electromigration methods is reviewed. The present work presents and discusses the main CE applications performed in Food Science and Technology including the new field of Foodomics, reviewing recent results on food quality and safety, nutritional value, storage, bioactivity, as well as applications of CE for monitoring food interactions and food processing. The CE analysis of a large variety of food-related molecules with different chemical properties, including amino acids, peptides, proteins, phenolic compounds, carbohydrates, DNA fragments, vitamins, toxins, pesticides, additives, and other minor compounds is described. The use of microchips, CE-MS, and chiral-CE in food analysis is also discussed as well as other current and foreseen trends in this area of research. Following the previous review by Castro-Puyana et al. (Electrophoresis, 2012, 33, 147–167), the current review covers the papers that were published from February 2011 to February 2013.
