What is Sunset Yellow?

Sunset Yellow (E number E110) is chemically known as potassium sodium disulfonate tartrate or lemon yellow, with a molecular formula of C16H10N4Na2O7S2 and a molecular weight of 452.38 g/mol. It belongs to the azo pigment class and is formed by the condensation of aromatic amines derived from coal tar (such as p-aminobenzenesulfonic acid) with phenols (such as 2-naphthol) under acidic conditions.

Sunset Yellow has good solubility in water and exhibits a bright yellow color. It has relatively good light resistance, heat resistance, and acid and alkali resistance, which makes it a widely used food additive, especially in food processing where color stability is required.

During the synthesis process, the starting material is converted into the target molecular structure through a specific chemical reaction, followed by purification and treatment to ensure that it meets food safety standards.
