Phosphoric Acid (Food use)

Its purpose in the food industry is to give a sharp flavour to food or to serve as a preservative. The most widely consumed source of phosphoric acid is soft drinks. Phosphoric acid is responsible for the characteristic biting taste associated with colas.

In addition to colas, many sports drinks, bottled teas, punches and fruit-flavoured beverages contain phosphoric acid. The salts of phosphoric acid are used in many dairy products to modify the proteins and alter the pH to produce a higher-quality product. The addition of phosphates derived from phosphoric acid to cheese results in smooth, shelf-stable products. Phosphoric acid or phosphates can also be found in milk, buttermilk, cottage cheese and non-dairy coffee creamers.
