Is e151 vegan?

E151 is a synthetic food coloring known by the common name Brilliant Black BN or Black PN. It is an artificial black azo dye that is manufactured through chemical synthesis derived from petroleum products. Food producers use this water-soluble coloring agent to provide a deep violet to black tint to a variety of commercially processed foods. Common applications include confectionery, liquorice, cake decorations, soft drinks, dessert mixes, ice cream, sauces, and artificial caviar substitutes.

This ingredient is vegan because it is entirely synthetic and contains no animal products. The synthesis of Brilliant Black BN relies exclusively on petrochemical and mineral chemical precursors that undergo standardized industrial chemical reactions. Neither animal tissues, animal-derived enzymes, nor animal byproducts are involved in the formulation or purification of the dye. Because E151 has no animal origin at any stage of its production, it is considered suitable for vegans.
