“…Various methods for the determination of dyes in foods have been reported, including capillary electrophoresis [6][7][8][9][10], thinlayer chromatography [11], ion-pair chromatography [12,13], high performance liquid chromatography (HPLC) with ultraviolet/visible (UV/Vis) or diode-array detector (DAD) detection [14][15][16][17][18][19][20][21][22][23][24][25] and liquid chromatography-mass spectrometry (LC-MS) [26][27][28][29][30][31][32]. HPLC coupled with UV/Vis or DAD detection is the most commonly used technique because dyes absorb strongly at the ultraviolet and/or visible wavelength.…”

“…Besides, false positives caused by complex food matrices are frequently encountered [6,18]. To solve these problems, the selective detection by liquid chromatography tandem mass spectrometry (LC-MS/MS) has been used [26][27][28][29][30][31][32] for it can provide detailed structural information. In the selective reaction monitoring (SRM) mode, the specific MS transition (precursor ion → product ion) can exclude the presence of interference substances, improving the accuracy of the quantification.…”

a b s t r a c tA method combining solid phase extraction with high performance liquid chromatography-electrospray ionization tandem mass spectrometry was developed for the highly sensitive and accurate screening of 40 dyes, most of which are banned in foods. Electrospray ionization tandem mass spectrometry was used to identify and quantify a large number of dyes for the first time, and demonstrated greater accuracy and sensitivity than the conventional liquid chromatography-ultraviolet/visible methods. The limits of detection at a signal-to-noise ratio of 3 for the dyes are 0.0001-0.01 mg/L except for Tartrazine, Amaranth, New Red and Ponceau 4R, with detection limits of 0.5, 0.25, 0.125 and 0.125 mg/L, respectively. When this method was applied to screening of dyes in soft drinks, the recoveries ranged from 91.1 to 105%. This method has been successfully applied to screening of illegal dyes in commercial soft drink samples, and it is valuable to ensure the safety of food.

“…Dyes in their anionic forms are poorly retained in RP-LC systems, which may be explained by electrostatic repulsion between anions and the deprotonated residual silanol groups present on the silicabased stationary phase. Separation of different dyes is most often performed in reversed phase (RP) or ion pair (IP) systems, while quantitative analysis is usually based on measurements via UV-VIS detection, especially using diode array detector (DAD) (Fuh and Chia 2002;Kiseleva et al 2003, Tuzimski andWoźniak 2008;Culzoni et al 2009;Tuzimski 2011;Yan et al 2012;Petigara Harp et al 2013;Zou et al 2013;De Andrade et al 2014;Li et al 2015;Qi et al 2015;Šuleková et al 2016), or employing MS (Fuh and Chia 2002;Sun et al 2007;Pardo et al 2009;Feng et al 2011;Liu et al 2011;Chen et al 2013;Li et al 2013;Zou et al 2013;Li et al 2014;Jia et al 2014;Li et al 2015;Tsai et al 2015;Qi et al 2015). There are also some literature reports devoted to utilization of gas chromatography coupled with MS (GC-MS) (Otero et al 2016) or capillary electrophoresis (CE) (Del Giovine and Bocca 2003;Huang et al 2005;Prado et al 2006) for food colours analysis.…”

A simple, inexpensive and robust high-performance liquid chromatography diode array detector (HPC-DAD) procedures are proposed to analyse food dyes in beverages, hard candy and fish roe samples. An ether-linked phenyl stationary phase provides sufficient selectivity and chromatographic performance for separation of 11 sulfonated azo dyes. Beverage samples were only diluted (and degassed when needed) before analysis. Solidphase extraction (SPE) or matrix solid-phase dispersion (MSPD) procedures are proposed for efficient extraction of the analytes from candies or fish roe samples, respectively. Limits of detection (LODs) were from 0.005 to 0.013 μg mL −1 and limits of quantification (LOQs) between 0.014 and 0.038 μg mL −1. HPLC-DAD method was validated in terms of intra-and inter-day accuracy and precision at three concentration levels 2, 1, and 0.1 μg mL −1. Validation was also performed for SPE and MSPD extraction procedures including intra-and inter-day accuracy (Recovery %) and precision (RSD%), as well as intralaboratory reproducibility. Application to analysis of beverages and food samples available to consumers proved that described methods are suitable for the routine analysis of dyes in food products.

A sensitive and fast method for the quantification of the illegal dye chrysoidine in aquaculture products with ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) is presented. Muscle tissues were made alkaline with sodium hydroxide and extracted with ethyl acetate. After evaporation and subsequent defatting with n-hexane, extracts were directly injected onto the UPLC-column. Chromatography was performed on a C(18) column using 0.1% formic acid in water and an acetonitrile gradient within 6 min. Mass spectrometric analysis was performed in the positive electrospray MS/MS mode. The limit of quantification was 0.25 ng/g, which was 30 times lower than the only previously published method with gas chromatographic detection. A complete validation according to the scientific literature and as defined by the European Union was performed. The applicability of the method was shown in the analysis of more than 50 unknown samples in the framework of a monitoring program.
