Allgemeine Beschreibung

Allura red AC (E29) is a mono azo dye, added as a synthetic colorant to various drinks, juices, bakery, meat, and sweets products. It has been approved for use as a food additive by European Union (EU) Register as per Annex I of Directive 94/36/EC. The USA Food and Drug Administration (FDA) has approved its use in food, drugs, and cosmetics as a substitution for amaranth (Red 2) and erythrosine (Red 3). It is commonly known as Food Red No. 40 and Food, Drug, and Cosmetics Red No. 40 (FD&C Red No. 40).

Anwendung

The analytical standards can also be used as follows:
  • Hydrophobic deep eutectic solvents (HDES) based liquid-phase microextraction (LPME) of Allura Red AC and tartrazine in food samples for their quantification by UV-Vis spectrophotometry
  • Nanomolar-level determination of Allura red in soft drink powder samples using a voltammetric electrochemical sensor based on a glassy carbon electrode (GCE) modified with cross-linked chitosan film incorporated with carbon black particles and ionic liquid,1 -butyl-3-methylimidazolium tetrafluoroborate
  • Simultaneous analysis of Sunset Yellow FCF, Allura Red AC, Quinoline Yellow WS, and Tartrazine in gummy bears, chewing gum, and sweet candy samples by reversed phase-high-performance liquid chromatography (RP-HPLC) coupled with UV detection
  • Construction of an electrochemical sensor based on cobalt complex decorated carbon paste electrode (CoC/CPE) for the cyclic voltametric determination of tartrazine, sunset yellow, and Allura red in gelatin and pharmaceutical dosages of acetaminophen
  • Multi-residue analysis of 20 synthetic dyes in 18 chili powders and six syrup-preserved fruit samples by liquid chromatography-tandem mass spectrometry (LC-MS/MS)
