Tartrazine (E102) is a synthetic lemon-yellow azo dye used as a food coloring.

It is found in a wide range of products such as soft drinks, desserts, candies, and snack foods to give them a vibrant yellow appearance.

While approved by many regulatory agencies, tartrazine has been linked to allergic reactions, such as hives, in a small portion of the population. Some studies have also suggested a link to increased hyperactivity in children, particularly when consumed with other additives like benzoates.

Sunset Yellow FCF (also known as Orange Yellow S, or C.I. 15985) is a petroleum-derived orange azo dye with a pH dependent maximum absorption at about 480 nm at pH 1 and 443 nm at pH 13 with a shoulder at 500 nm. When added to foods sold in the US it is known as FD&C Yellow 6; when sold in Europe, it is denoted by E Number E110.

Allura Red AC is a red azo dye that goes by several names, including FD&C Red 40. It is used as a food dye and has the E number E129. It is usually supplied as its red sodium salt, but can also be used as the calcium and potassium salts. These salts are soluble in water. In solution, its maximum absorbance lies at about 504 nm.

BRILLIANT BLUE FCF (Blue 1) is an organic compound classified as a blue triarylmethane dye, reflecting its chemical structure. Known under various commercial names, it is a colorant for foods and other substances.

Citric acid is a natural organic acid found in citrus fruits such as lemons, oranges, and limes.

It is widely used in the food industry as a flavor enhancer, acidulant, and preservative due to its tart and refreshing taste.
