Potassium Phosphates And Sodium Phosphates

Potassium and sodium phosphates are mineral salts that occur naturally in the body and in foods. They are manufactured by combining phosphorus compounds with potassium or sodium. These salts are commonly used as food additives.

Manufacturers add potassium and sodium phosphates to foods to help control acidity, improve texture, and act as emulsifiers, helping to blend ingredients like oil and water. They are frequently found in dairy products, processed meats, and baked goods.

Potassium and sodium phosphates are generally recognized as safe (GRAS) by the FDA when used as food additives. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated phosphates and established acceptable daily intakes. While essential minerals, excessive intake of phosphates, particularly from processed foods, may be a concern for individuals with kidney disease. Evidence on the long-term effects of high phosphate intake from food additives is still being studied.
