Sodium And Potassium Phosphate

Sodium and potassium phosphates are salts made from combining sodium or potassium with phosphate. They are often produced industrially by reacting a source of sodium or potassium with phosphoric acid. These compounds can exist in various forms, such as monosodium phosphate, disodium phosphate, monopotassium phosphate, and dipotassium phosphate.

These phosphates are added to foods to help control acidity, improve texture, and act as emulsifiers, meaning they help ingredients like oil and water mix and stay mixed. They are commonly found in processed cheeses, dairy products, meats, and baked goods to improve moisture retention and stability.

Sodium and potassium phosphates are generally recognized as safe (GRAS) by the FDA for use in food. The FDA monitors their use to ensure they are safe when consumed at levels typically found in food. JECFA and EFSA have evaluated phosphates and established acceptable intake levels. While essential minerals, excessive intake of phosphates, particularly from supplements or in individuals with kidney issues, can be a health concern, though this is rarely due to food sources alone.
