Determination of additives and organic contaminants in food by CE and CEC

Abstract

The application of CE to the analysis of additives and organic contaminants in food since 2001 has been reviewed. Additives included in the review are dyes, preservatives, antioxidants and sweeteners. Organic contaminants included in the review are pesticides, antibiotics and those produced during processing or cooking food. The review highlights the strategies and approaches adopted in making CE suitable for the determination of analytes at residue level and in complicated matrices.

A rapid quantitative determination of phenolic acids in Brassica oleracea by capillary zone electrophoresis

“…CE is a modern separation technique which has been used increasingly in the last decade for food analysis (Boyce, 2007;Cifuentes, 2006;Lee, Boyce, & Breadmore, 2010). Due to short analysis time, low sample volume required, minimal reagents used and low running costs, it has proved to be a highly efficient analytical technique that both rivals and complements HPLC.…”

Recent food safety and food quality applications of CE‐MS

“…In spite of the strong efforts that have been made over the last years to extend the applications of CE in food safety and food quality [4][5][6][7][8][9][10][11], the number of works published in these fields is still low when compared with other analytical techniques such as GC or HPLC (the most pronounced prospects of CE-MS lie in the fields of proteomics and metabolomics.). Even though, in the last decade, and especially in the last years, CE-MS has gained popularity in food analysis as an alternative to GC or HPLC because of the inherent characteristics/advantages of the technique [4][5][6][7][8][9][10][11].…”

An Analytical Task: a Miniaturized and Portable µConductometer as a Tool for Detection of Pesticides

“…Therefore monitoring of environment pollution by pesticides is still concern in both developed and developing countries ( Analytical task: Development of low cost and sensitive methods for the determination of pesticides in the environment is needed (Andrade-Eiroa et al, 2002;Heinisch et al, 2005;Heinisch et al, 2004;Taylor & Grate, 1995;Wegner et al, 2005). For direct detection of these molecules hyphenated techniques such gas or liquid chromatography with mass spectrometry (Alder et al, 2006;Hercegova et al, 2007;Hernandez et al, 2005;Lacorte & Barcelo, 1996;Lambropoulou & Albanis, 2007;Popp et al, 1997;Rodriguez-Mozaz et al, 2007;Sancho et al, 2006), capillary electrophoresis (Boyce, 2007;Ravelo-Perez et al, 2006), thin layer chromatography (Sherma, 2007) coupled with various detectors are used. These methods are often time-consuming, demanding on high-cost instrumentation and most of all, lack any no possibility of miniaturization.…”
