The synthetic food dyes studied were rose bengal (RB), phroxine (PL), amaranth, erythrosine B (ET), allura red, new coccine, acid red (AR), tartrazine, sunset yellow FCF, brilliant blue FCF, and indigo carmine. First, data confirmed that these dyes were not substrates for CYP2A6, UGT1A6, and UGT2B7. ET inhibited UGT1A6 (glucuronidation of p-nitrophenol) and UGT2B7 (glucuronidation of androstero...

Dental plaque is a bacterial biofilm structure, neatly organized and attached to the tooth surface, which contains inorganic components such as calcium phosphorus derived from saliva. Bacteria in that stick surface of teeth will provide place for new bacteria grow. Disclosing solution coloring agent works change color dental contrast with white surface. Erythrosine red commonly used disclosing ...

Erythrosine (ErB) is a xanthene and an US Food and Drug Administration approved dye used in foods, drugs and cosmetics. Although its utilization is permitted, ErB is described as inhibitor of enzymes and protein-protein interactions and is toxic to pituitary and spermatogenesis processes. However, the genotoxicity and mutagenicity of ErB is inconclusive in the literature. This study aimed to an...

in this study, the trace amounts of erythrosine, as a food dye is determined by cloud point extraction-scanometry (cpe-scanometry) as a new, facile, available, fast, sensitive, and low cost method. the method is based on the cpe of analyte from aqueous solution, diluting the extracted surfactant-rich phase with ethanol, transfer to plexiglas®cell and scanning the cells containing the analyte so...

In this study, Copper oxide as a good and inexpensive adsorbent has been introduced and used for the removal of erythrosine and red carmoisine dyes from several water solutions successfully. The effect of various parameters such as pH, dye concentration, amount of adsorbent, contact time and temperature on removal processing was investigated. Adsorption isothermal data could be interpreted by t...

Male rats were treated of with a diet supplemented daily by the synthetic food colour erythrosine (0.08 and 0.4 g/kg diet) for 30 days. Changes in mutagenic activities, as an index for evaluating of possible toxic effects, were monitored by measuring chromosomal aberrations of rat bone marrow, nucleic acids and total protein concentrations of rat liver and brain. The present study found that er...

The present work was designed to test the toxic impacts exerted by the colour additives erythrosine on the histology, ultrastructure and some serum liver function parameters in male albino rats. Erythrosine in a dose level equals 136 mg/kg bw was given orally to male albino rats for 4, 6 and 8 weeks. This caused time-dependent histological alterations in liver such as cytoplasmic vacuolization ...
