What it is
Sodium phosphates are salts formed from sodium and phosphate. They are commonly produced industrially by reacting phosphoric acid with a sodium source, like sodium carbonate or sodium hydroxide. In food, they are often used in combination.
Why it's used
Sodium phosphates act as preservatives, emulsifiers, and acidity regulators. They help retain moisture in meats and seafood, prevent spoilage, and improve texture. They are frequently found in processed meats, seafood, dairy products, and baked goods.
Health notes
Sodium phosphates are generally recognized as safe (GRAS) by the FDA when used for their intended purpose in food. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated sodium phosphates and established acceptable daily intakes. High intake of phosphates, particularly from supplements or processed foods, has been linked in some studies to potential cardiovascular and kidney issues, but evidence is mixed and more research is needed to confirm these links at typical dietary intake levels.
Allergen info
Sodium phosphates are not derived from any of the 9 FDA major allergens. They do not contain gluten.
