Simultaneous Determination of the Colorants Sunset Yellow FCF and Quinoline Yellow by Solid-phase Spectrophotometry Using Partial Least Squares Multivariate Calibration

Abstract

A method for the simultaneous determination of the colorants Sunset Yellow FCF and Quinoline Yellow using solid-phase spectrophotometry is proposed. The colorants were isolated in Sephadex DEAE A-25 gel at pH 5.0, the gel-colorants system was packed in a 1 mm silica cell and spectra were recorded between 400 and 600 nm against a blank. Statistical results were obtained by partial least squares (PLS) multivariate calibration. The optimized matrix by using the PLS-2 method enables the determination of the colorants in artificial mixtures and commercial soft drinks.

Sensitive and rapid determination of quinoline yellow in drinks using polyvinylpyrrolidone-modified electrode

“…1 has been widely used as additives in the food industry (Capitan-Vallvey, Fernandez, deOrbe, Vilchez, & Avidad, 1997). However, studies have proven that quinoline yellow is genotoxic, and its genotoxicity has been confirmed using the cellular model systems, human lymphocytes in vitro (Macioszek & Kononowicz, 2004).…”

Rapid detection of quinoline yellow in soft drinks using polypyrrole/single-walled carbon nanotubes composites modified glass carbon electrode

“…Compared with natural pigments, synthetic dyes have been widely used in foods due to their advantages such as good color uniformity, low production cost, well water solubility, and excellent stability. Quinoline yellow is one of those synthetic colorants [1]. However, studies have shown that quinoline yellow has detrimental effects on children's behavior, such as hyperactivity, irritability, impulsiveness, inattention, lack of basic social skills and self-control, as well as some neurological diseases [2,3].…”

Selective Voltammetric Determination of Tartrazine in the Presence of Red 10B by Nanogold‐modified Carbon Paste Electrode

“…Simultaneous determination of Tartrazine with different colorants or other compounds was studied in the literatures. [18][19][20][21][22][23][24][25][26][27][28] But, to the best of our knowledge, the voltammetric determination of Tartrazine in the presence of Red 10B using a NG-CPE has not hitherto been reported. The electrochemical behavior of Tartrazine suggested that NG-CPE exhibits an electrocatalytic effect on the oxidation of Tartrazine, since it greatly enhances the oxidation peak current of Tartrazine as well as lowering its oxidation overpotential.…”
