Disodium phosphate is a chemical added to foods, cosmetics, and other products. It’s useful as a

preservative and a flavor enhancer, among other things.

This artificial type of salt is made from the elements sodium and phosphorus. Chemists create it in a lab.

They break down naturally-occurring phosphate rock and combine it with sulfuric acid and other substances.

Some foods like legumes and wheat products naturally have similar phosphates. Processed foods usually have much higher levels of disodium phosphate as an additive.

Disodium phosphate falls into the larger category of sodium phosphates that are used in consumer products. It looks like a white, grainy powder.

Disodium phosphate is a food additive that combines the minerals phosphate, or phosphorus, and sodium. Phosphate salts are also sometimes used as medicine, and they're generally regarded as safe by the U.S. Food and Drug Administration. People with certain health conditions requiring low phosphorus intakes, however, may want to minimize the amount of disodium phosphate they consume.

Use in Food

When used as a food additive, disodium phosphate plays a number of roles. It can help regulate the acidity of food, thicken it, stabilize it and maintain it at the proper moisture level. Disodium phosphate also helps keep oil-based and water-based ingredients, which would otherwise separate, mixed together.

Potential Food Sources

Fish and seafood sometimes contain disodium phosphate to help keep them moist. Otherwise, they lose significant amounts of water during processing and storage. Disodium phosphate also helps preserve sausages and cooked meats and make soft drinks and cheese smooth. It helps preserve bakery products and enriched farina and maintain the smoothness of ice cream and artificially sweetened jelly. A wide variety of other foods can also contain disodium phosphate, including breading or batters, breakfast cereal, candied fruit, butter, chewing gum, cocoa and chocolate products, fruit juice products, coffee, tea, cider, dairy products, candy, processed vegetables, pudding, pasta, alcoholic beverages, sausage casings, egg- or fat-based desserts, salt, salt substitutes, soups, tofu, sweeteners and water-based beverages.

Other Uses

Disodium phosphate has nonfood applications, too. It can be used in water treatment and as a flame retardant. In medicine, it may help lower high blood levels of calcium or increase low blood levels of phosphate. It may also be helpful for limiting some types of kidney stones, but the evidence for this is still preliminary, according to MedlinePlus.
