Each Of The Following: Phosphoric Acid

Phosphoric acid is a mineral acid that occurs naturally in many foods, including fruits and grains. It is manufactured industrially from phosphate rock. In food processing, it is typically used as an acidulant, providing a tart or sour taste.

Phosphoric acid is used to add acidity and a sharp, tangy flavor to foods and beverages, especially colas and other soft drinks. It also acts as a preservative by lowering pH, and can be used as a chelating agent to bind metal ions.

Phosphoric acid is generally recognized as safe (GRAS) by the FDA for use in food. High intake of phosphoric acid, particularly from sodas, has been linked in some studies to lower bone mineral density, though evidence is mixed and other factors like calcium intake are important. JECFA and EFSA have evaluated phosphoric acid and its salts, establishing acceptable daily intakes. Concerns about its effect on bone health are debated, with some research suggesting a link and others finding no significant association when calcium intake is adequate.
