“…Due to these regulatory restrictions, new methods are still demanded for rapid detection and identification of colorants in food products . Following this trend, a new method based on partial filling MEKC for the quantitative determination of Sudan dyes (I, II, III, and IV) in chilli sauces was developed Under optimized conditions, the azo dyes are baseline separated in less than 8 min with LODs ranging from 0.57 to 0.71 μg/mL (S/N > 3). Using an internal standard, the repeatability of the quantitative determination is improved almost four times.…”

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.

“…As stated above, the PF approach is one of the most widely used choices for developing practical MEKC‐MS determinations; however, there have been relatively few reports on these topics in the reviewed period. Fukuji et al accomplished the fast determination of Sudan dyes in chilli tomato sauces by PF‐MEKC; for separation, they filled 25% of the capillary with a BGE consisting of 40 mM NH 4 HCO 3 , 25 mM SDS, and 32.5% v/v ACN, and the rest of the capillary with a similar BGE containing no SDS. These experimental conditions are compatible with MS detection and allowed the rapid screening and determination of Sudan dyes in spiked chilli sauce samples with recoveries from 85 to 99%.…”

This review article addresses recent methodological and instrumental innovations in MEKC with emphasis on practical aspects. Like its predecessors, this review is intended to provide an updated overview covering work on the most salient methodological contributions to enhancing sensitivity and resolution in MEKC-based determinations published over the past two years. The most widespread approaches to enhancing sensitivity, which include improving "classical" online sample concentration techniques, combinations of on- and off-line sample concentration protocols and recent developments are discussed, and so are modifications of existing MEKC systems with various micellar phases, the use of BGE additives (organic modifiers, chiral selectors, gold nanoparticles) and coated capillaries, and the implementation of 2D separations and chemometric methods to enhance resolution. Instrumental approaches such as MS and LIF are also discussed, and proposals for overcoming the problems typically encountered in directly coupling MEKC with MS, and the recent inception of quantum dots with a great potential for LIF detection in MEKC, are also dealt with. Finally, foreseeable developments on potential future directions are also expressed.

“…In the past decade, in light of the increasing and widespread illegal uses of Sudan dyes in food around the world, many studies have been developed to identify and quantify Sudan dyes in foodstuff [10–14]. Previous studies have adopted micellar electrokinetic chromatography and capillary electrophoresis to detect Sudan dyes in foodstuff [15–17]. More recently, liquid chromatography mass spectrometry (LC-MS) or liquid chromatography tandem mass spectrometry (LC-MS/MS) has been used for the analysis of Sudan dyes because of its high sensitivity and selectivity [18–21].…”

A rapid and simple ultra-high-performance supercritical fluid chromatography (UHPSFC) with photodiode array (PDA) method was developed and validated for simultaneous determination of eight Sudan dyes in chili oil. In particular, a pair of isomer, Sudan red B and Sudan IV, was included in the analysis. After being diluted with dichloromethane, the analytes were separated on an Acquity UPC2 HSS C18 SB column with gradient elution using CO2 as the mobile phase and acetonitrile/methanol (v/v, 45/55, containing 0.1% formic acid) as the organic modifier. Analytes were quantified by external calibration curves over ranges of 0.5–50 mg/L, with correlation coefficients above 0.999. The method gave recoveries of the target compounds (spiked at levels of 1, 5, and 25 mg/kg) ranging from 82.6 to 108.3%, with intraday and interday relative standard deviations of less than 8.0% and 8.6%, respectively. The limits of detection (LODs) and the limits of quantification (LOQs) for eight dyes were from 0.10 to 0.30 mg/kg and 0.30–1.00 mg/kg, respectively. This method was applied for the analysis of chili oil samples collected from the supermarket in Beijing. This validated that the UHPSFC-PDA method provides a useful strategy for the simultaneous determination of Sudan dyes in chili oil for routine analysis.
