Colour Chemistry
Allura Red AC is a synthetic monoazo dye. Its colour arises from the extended conjugated π-electron system across the azo (–N=N–) bridge, absorbing maximally at ~504 nm to yield a bright red hue. Disodium sulfonate groups ensure water solubility and stability across food pH 3–8. Resistant to moderate heat and standard food-processing conditions; bleached by strong oxidising agents or prolonged UV irradiation.
