Disodium phosphate is the inorganic compound with the formula Na2HPO4 and it is the sodium salt derived from phosphate rock in the earth. It is made by combining phosphoric acid, derived from phosphate rock, with soda ash.
It is crystallized and purified for use in products. Disodium hydrogen orthophosphate as a curing agent helps in maintaining the pH or acidity of the product produced.
By combining this material with fluoride and phosphoric acid acidulated phosphate fluoride solution as outlined in the FDA’s Antiquaries monograph is formed. That solution promotes remineralization and helps prevent enamel dissolution. This product is a food additive that contains phosphate or phosphorus and sodium minerals.
Phosphate salts also have some drug use and are generally considered safe by the US Food and Drug Administration.

Applications of Disodium phosphate
Disodium phosphate plays many roles as a food additive This can help regulate the acidity of the food, its shelf life, and maintain the proper moisture level.
Potential Food Sources
Fish and seafood sometimes contain Disodium hydrogen orthophosphate to help keep them moist
Disodium phosphate was sometimes used to preserve the moisture of fish and seafood because it helps maintain its moisture. Otherwise, these products lose a significant amount of water during processing and storage.
It is also used as a preservative in the production of breads, artificial sweeteners and ice cream sausages and cooked meats.
To produce a wide variety of food products, disodium phosphate is used as a preservative, including: Bread and cereals, fruit candies and add-ons such as coffee juice, pasta and sausages, etc.
It also has non-food uses. It can be used in water treatment and as a flame retardant. In medicine, it may also help lower blood calcium levels or increase blood phosphate levels. According to MedlinePlus, it may also be useful to limit some types of kidney stones
