“…These data are shown in Table 3. The recovery of ER from standard solutions was 61 -73.5 % in accordance with that reported by Kirschbaum et al (2006) for the recovery rates of standard ER solution (0.28 mM) retained on various types of polyamide adsorbents. These authors had noticed that the performance of the adsorbent may vary depending on the manufacturing process or/and lot-to-lot variability of the polymeric material.…”

“…Traditional methods use HPLC coupled with UV/Vis or DAD detection for determining dyes in foods [20][21][22]. However, multiple isomers and structural analogs of the dyes are difficult to separate and determine.…”

“…However, SPE cleanup was still necessary for some fruit drinks or juices. Traditionally used for dye cleanup, polyamide column, however, does not retain xanthenes dyes such as erythrosine [21,23]. In this study, a HLB SPE column was chosen for its dual functionality: hydrophilic N-vinylpyrrolidone and lipophilic divinylbenzene.…”

“…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.…”

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.

“…Detected amounts of dyes in fish roe samples (from 67.3 to 237.8 μg g To the authors best knowledge, this is the second analytical procedure devoted to artificial colourants analysis in caviar/ ) and RSD% on the basis of triplicates are given in Table 6 fish roe samples. According to Web of Science search (queries in topic area: 'caviar and dye' or 'fish roe and dye' or 'caviar and colourants'), only one article by Kirschbaum et al is found (Kirschbaum et al 2006). The method elaborated by the authors relays on ultrasound-assisted extractions with 1 M aqueous ammonia followed by extraction of dyes using polyamide A sorbent.…”

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.
