Sigma-Aldrich offers a number of Allura Red AC products. The decolorization and mineralization of solutions containing 230 mg L(-1) of the food azo dye Allura Red AC at pH 3.0 have been studied upon treatment by electrochemical oxidation with electrogenerated H2O2 (EO-H2O2), electro-Fenton (EF) and photoelectro-Fenton (PEF).METHODS AND RESULTS: Experiments were performed with a stirred tank reactor containing a boron-doped diamond (BDD) or Pt anode and an air-diffusion cathode to generate H2O2. The CD and Raman spectra showed that the binding of Allura Red AC to HSA induces the rearrangement of the carbonyl hydrogen-bonding network of polypeptides, which changes the HSA secondary structure. Absorbance(E1%1cm) min. Allura Red AC has the ability to quench the intrinsic fluorescence of HSA through static quenching. COLOUR- Dark Red Powder WATER (gm/ltr) - 220.00 GLYCERIN (gm/ltr) - 30.00 PROPYLENE GLYCON (gm/ltr) - 15.00 ETHANOL (95%) (gm/ltr) - … Enter C1, C2 & V2 to calculate V1. The decolorization and mineralization of solutions containing 230 mg L(-1) of the food azo dye Allura Red AC at pH 3.0 have been studied upon treatment by electrochemical oxidation with electrogenerated H2O2 (EO-H2O2), electro-Fenton (EF) and photoelectro-Fenton (PEF). The safety of several azo colouring agents, used as food additives, has during the years been questioned. Allura Red AC dye's production and use as a color additive in foods, drugs and cosmetics may result in its release to the environment through various waste streams. Results show that Allura Red AC has the ability to quench the intrinsic fluorescence of HSA through static quenching. The effective oxidation of final oxalic and oxamic acids by BDD along with the photolysis of Fe(III)-oxalate species by UVA light accounted for the superiority of PEF with BDD.

In this study we have evaluated whether Allura Red is genotoxic using a flow cytometer-based micronucleus assay in peripheral blood of mice. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed
If released to air, Allura Red AC dye will exist solely in the particulate phase in the atmosphere since it is a salt and will be nonvolatile. Antibodies, Dye

What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution? It has very good stability to light, fair to poor stability to oxidation, good stability to heat, and shows no appreciable change in stability in 10% sugar systems. We do not sell to patients.

NH4(+), NO3(-) and SO4(2-) ions were released during the mineralization. TCI utilise des cookies pour personnaliser et améliorer votre expérience utilisateur. The analyses did not show any significant difference in the %PCE or in the fMNPCE. In fact, in the European Union, Allura Red is permitted as a food additive in human food, but, surprisingly, it was not acceptable as an additive for use in animal feed. The answer of 100 microliter (0.1 ml) appears in the Volume (start) box. It has a yellowish-red hue and has a very good … The CD spectrum of β-LG contains single minima at ∼218nm, which shifts towards higher wavelength minima at ∼225nm in the presence of Allura Red, characteristics of the cross β-sheet structure.

At 37 degrees C the minimum concentration of Amaranth and Allura red at which significant DNA damage observed through comet assay was 1,250 mug/mL in 2nd h post exposure time. More... Validated by Experts, Validated by Users, Non-Validated, Removed by Users. METHODS AND RESULTS:Concentrations of Amaranth and Allura red were maintained in sorbitol buffer starting from 9.76 to 5,000 μg/mL and 1 × 10(4) cells were incubated at two different incubation temperatures 28 and 37°C. Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
The tested doses were 0, 100, 200, 400, 600, 800, 1000, 1500, and 2000 mg/kg body weight (b.w.). Allura Red AC Dye. Allura Red AC. 497.0 to 501.0 nm(0.02mol/L AcONH4 sol.) PEF process with BDD yielded almost total mineralization following similar trends in SO4(2-), ClO4(-) and NO3(-) media, whereas in Cl(-) medium, mineralization was inhibited by the formation of recalcitrant chloroderivatives. Allura Red AC (FD&C Red #40) is a colorant. disodium;6-hydroxy-5-[(2-methoxy-5-methyl-4-sulfonatophenyl)diazenyl]naphthalene-2-sulfonate, CC1=CC(=C(C=C1S(=O)(=O)[O-])OC)N=NC2=C(C=CC3=C2C=CC(=C3)S(=O)(=O)[O-])O.[Na+]. The oxidation ability increased in the sequence EO-H2O2 < EF < PEF and faster degradation was always obtained using BDD.
