The analysis of food components using capillary electromigration methods is reviewed in this work. Papers that were published from February 2009 to February 2011 are included following the previous review by Herrero et al. (Electrophoresis, 2010, 31, 205-228). The analysis of amino acids, biogenic amines, peptides, proteins, DNAs, carbohydrates, phenols, polyphenols, pigments, toxins, pesticides, vitamins, additives, small organic and inorganic ions and other compounds found in foods and beverages are reviewed, as well as those applications of CE for monitoring food interactions and food processing. 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 including new developments in Foodomics.

“…4 Fast green FCF (Scheme 1) is a sea green triarylmethane synthetic food dye, also known as Food Green 3, FD and C Green no. The electro and spectrochromatographic methods reported for the determination of color additives in food products such as high performance liquid chromatography (HPLC) with photodiode array detection, 6,7 HPLC with UV detection, 8 HPLC-diode array detection, 9 green chromatography, 10 HPLC-diode array detector-electrospray mass spectrometry, 11 capillary electrophoresis spectrophotometric detection, 12 HPLC with UV-DAD detection, 13 LC-UV detection, 14 LC-electrospray mass spectrometry, 15 HPLC and TLC-spectrophotometry, 16 The social claim for newly developed analytical methods is not only selectivity and sensitivity but also the method needs to be Green. It can be used for tinned green peas and other vegetables, jellies, sauces, fish, desserts, and dry bakery mix at levels of up to 100 mg/kg.…”

However the optical methods based on absorption and uorescence are more simple and less expensive.…”

Fluorescent Tetracene Nanoparticles (TNPs) have been prepared by a reprecipitation method using cetyl trimethyl ammonium bromide (CTAB) as a stabilizer. These TNPs are more photostable against photobleaching and high solubility in water minimize the utilization of hazardous organic solvents compared with single organic fluorophore in sensing applications. The method based on fluorescence quenching TNPs as a novel fluorescent sensor for selective recognition of fast green FCF dye in aqueous solution. The fluorescence intensity of TNPs was quenched by the successive addition on increasing concentrations of fast green FCF dye. The fluorescence quenching results were found to fit the Stern-Volmer (S-V) relationship in the range of 0.5-7.0 µg L -1 with a correlation coefficient of 0.999. The limit of detection (LOD) was 0.136 µg L -1 . Moreover, the excited state lifetime of TNPs remains unchanged even after increasing concentration fast green FCF dye suggest that fast green FCF dye adsorbed over the surface of the nanoparticles to form non-fluorescent ground state complex i.e. nature of quenching process is static. The proposed method was successfully applied for the quantitative analysis of fast green FCF dye in commercial samples with no necessity of prior separation of analyte molecules form the interfering constituents.
