What ingredient, traditionally present in Coca-Cola since the 1880s, was omitted to produce the colorless White Coke syrup?

Answer

Caramel coloring

The standard, iconic brown hue of Coca-Cola is derived from the caramel coloring added to the syrup base, a component that had been integral to the formula since the late 19th century. For White Coke, this coloring agent was intentionally excluded. The process was relatively straightforward in terms of chemical removal, resulting in a liquid visually resembling water or clear alcohol. Crucially, removing the color was purely an aesthetic modification; the underlying flavor profile of the cola syrup itself was intended to remain identical to that of the standard, caramel-colored product.
