Lignin-based hydrophobic DESs extracts Sudan dyes from aqueous solution
International Journal of Biological Macromolecules, 2023As a synthetic pigment, Sudan red is commonly used as a food additive and is harmful to the human kidney and can even cause cancer. In this work, we developed a one-step strategy to synthesize lignin-based hydrophobic deep eutectic solvents (LHDES), which were fabricated via methyltrioctylammonium chloride (TAC) as hydrogen bond acceptor and alkali ...

“Fast peaks” in chromatograms of Sudan dyes
Journal of Chromatography A, 2007The analysis of Sudan dyes has gained considerable attention during last years. In several publications multiple peaks in chromatograms of Sudan III and Sudan IV have been detected. It is demonstrated in this work that if the sample is kept in darkness before analysis, only one chromatographic peak appears for Sudan III or Sudan IV.

Synthesis of Deuterium-Labeled Azo Dyes of the Sudan Family
Synthesis, 2008Carcinogenic amines are formed in vivo during the metabolism of Sudan azo dyes. The identification and assay of these polluting agents requires the availability of deuterated analogues. Accordingly, two series of derivatives labeled on the phenylazo and naphthol moieties were synthesized.

The induction of cytochrome P450 1A1 by Sudan Dyes
Journal of Biochemical and Molecular Toxicology, 2008AbstractAzo dyes form a major class of chemically related compounds that are ubiquitous in foods, paints, printing inks, cosmetics, and also used as biological stains in histological and histopathological laboratories and clinics. Sudan I, sudan III, and sudan IV have been classified as category 3 carcinogens by International Agency for Research on ...

Comparison of the toxicity of the dyes Sudan II and Sudan IV to catalase
Journal of Biochemical and Molecular Toxicology, 2017AbstractThe mechanisms of the toxicity of Sudan dyes to the key antioxidant enzyme catalase (CAT) were investigated by spectroscopic methods, calorimetry techniques, enzyme activity assay, and molecular docking. Results showed that Sudan dyes bound to CAT through hydrophobic force, which changed the microenvironment of tryptophan and tyrosine residues,

Electrochemical detection of Sudan red series azo dyes: Bibliometrics based analysis
Food and Chemical Toxicology, 2022Sudan red azo dyes are banned from food because of their carcinogenic properties. It is necessary to establish a method for the detection of Sudan azo dyes in food. Among them, electrochemical sensing technology has become a very potential analytical method for food detection because of its fast, sensitive and low price.

Production of the monoclonal antibody against Sudan 2 for immunoassay of Sudan dyes in egg
Analytical Biochemistry, 2012Many methods have been reported to determine the residues of Sudan dyes in food samples. Among the reported methods, enzyme-linked immunosorbent assay (ELISA) was a frequently used practical screen tool. In this study, a novel hapten of Sudan 2 was synthesized by coupling 4-amino-3-methylbenzoic acid to β-naphthol, and the monoclonal antibody against ...
