Side Effects of Phosphoric acid

03/04/2016 admin

Phosphoric acid, also called orthophosphoric acid, (H3PO4), is the most important oxygen acid of phosphorus. It is a clear colorless solid or syrupy liquid. Phosphoric acid is deliberately added to soft drinks to give them a sharper flavor. Food-grade phosphoric acid (additive E338) is used to acidify foods and beverages such as various colas and jams. It provides a tangy or sour taste. Various salts of phosphoric acid, such as monocalcium phosphate, are used as leavening agents.
