Product Application of Phosphoric acid CAS#7664-38-2

Phosphoric Acid is an acidulant that is an inorganic acid produced by using burning phosphorus in an extra of air, producing phosphorus pentoxide which is dissolved in water to shape orthophosphoric acid of various concentrations. it is a robust acid which is soluble in water. the acid salts are termed phosphates. it is used as a flavoring acid in cola and root beer liquids to grant acceptable acidity and sourness. it is used as a synergistic antioxidant in vegetable shorten- ings. in yeast manufacture, it is used to keep the acidic ph and grant a supply for phosphorus. it additionally features as an acidulant in cheese. it is additionally termed orthophosphoric acid.
