What it is

Monosodium phosphate (MSP) is a salt made from sodium and phosphate. It is produced by reacting phosphoric acid with a sodium source, such as sodium hydroxide or sodium carbonate. It is commonly found in powder or granular form.

Why it's used

Manufacturers add MSP to foods for several reasons, including as an acidity regulator, emulsifier, and nutrient supplement. It helps control the pH of foods, improves texture, and can be used in processed cheese to prevent fat separation. It is frequently found in baked goods, dairy products, and processed meats.

Health notes

In the U.S., monosodium phosphate is generally recognized as safe (GRAS) by the FDA when used as intended. It is a source of phosphorus, an essential mineral. High intake of phosphates, especially from processed foods, has been linked in some studies to potential negative health effects, but evidence is mixed and more research is needed. JECFA and EFSA have evaluated phosphates and established acceptable daily intakes.

Allergen info

Monosodium phosphate is not derived from any of the nine major allergens recognized by the FDA. It does not contain gluten.
