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

Abstract

This review work presents and discusses the main applications of capillary electromigration methods in food analysis and Foodomics. Papers that were published during the period February 2013-February 2015 are included following the previous review by Garcia-Cañas et al. (Electrophoresis, 2014, 35, 147-169). Analysis by CE of a large variety of food-related molecules with different chemical properties, including amino acids, hazardous amines, peptides, proteins, phenols, polyphenols, lipids, carbohydrates, DNAs, vitamins, toxins, contaminants, pesticides, residues, food additives, as well as small organic and inorganic compounds. This work includes recent results on food quality and safety, nutritional value, storage, bioactivity, as well as applications of CE for monitoring food processing. The use, among other CE developments, of microchips, CE-MS, and chiral CE in food analysis and Foodomics is also discussed.

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

“…Moreover, food quality validation as well as the evaluation of other biological properties of foods imply the use of robust, efficient, sensitive, and cost‐effective analytical methodologies. CE has been applied to analyze a huge number of food matrices related to either food analysis or Foodomics , as can be also confirmed by the information given in Table . Thus, due to its high separation efficiency and speed, together with the extremely small sample and reagents requirements, CE has demonstrated to be a very useful analytical tool in food science.…”

Capillary Electrophoresis Based on Nucleic Acid Detection as Used in Food Analysis

“…Thus, finding an approach that limits the influence of these factors as much as possible and consistently provides relatively accurate authentication is critical for food authentication and traceability. CE‐based genetic food safety analyses (Agrimonti and others ; Rodríguez‐Ramírez and others ; Costa and others ; Woolfe and others ; García‐Cañas and others ; Madesis and others ; Sentandreu and Sentandreu ; Acunha and others ) have numerous applications due to several advantages over these methods, as mentioned in introduction. For example, to prevent fraudulent labeling and to certify the origin of products, short sequence repeat (SSR)‐PCR‐MCE analysis was applied to discriminate pure Italian pigmented rice varieties from imported Asian blends (Garino and others ); simultaneously, a special algorithm was developed to analyze the raw output of the experiment to further improve the resolution of this technique.…”

A first approach using micellar electrokinetic capillary chromatography for the determination of fipronil and fipronil‐sulfone in eggs

“…However, to the best of our knowledge, there is no previous information related to the determination of fipronil using CE. It is well known that CE has been integrated in analytical laboratories within many fields, especially in pharmaceutical science and biochemistry, although its use has been extended to environmental and food analysis . Among all the previous mentioned separation techniques, CE is an interesting and green alternative due to its high separation efficiency and low solvent and sample consumption.…”
