  • Confectionery: Candies, gummies, and jellies frequently use Allura Red to achieve a bright red color.
  • Beverages: Soft drinks, flavored waters, sports drinks, and syrups often contain this dye to enhance visual appeal.
  • Baked goods: Used in cakes, pastries, and other baked items.
  • Snacks: Chips and other processed snack foods often use this dye for coloring.
