Not phosphoric acid.

Processed food use (of phosphoric acid)

It is also used to acidify foods and beverages such as various colas, but not without controversy as to its health effects. It provides a tangy taste, and being a mass produced chemical, is available cheaply and in large quantities. The low cost and bulk availability is unlike more expensive natural seasonings that give comparable flavors, such as ginger for tangyness, or citric acid for sourness, obtainable from lemons and limes. (However most citric acid in the food industry is not extracted from citrus fruit, but fermented by Aspergillus niger mould from scrap molasses, waste starch hydrolysates and phosphoric acid.)

What I meant was phosphoric acid is not mentioned in the list of ingredients on the bottles' labels.
