Phosphoric Acid

What is Phosphoric Acid?

Phosphoric acid also known as orthophosphoric acid or phosphoric(V) acid, is a mineral. 

Phosphoric Acid Usage in Food

Food-grade phosphoric acid is used to acidify foods and beverages such as various colas, but not without controversy regarding 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.

Phosphoric acid, used in many soft drinks (primarily cola), has been linked to lower bone density in epidemiological studies. [1]
