What it is

Sodium tripolyphosphate (STPP) is a synthetic inorganic salt. It is made from the reaction of sodium carbonate and phosphoric acid, which are both common industrial chemicals.

Why it's used

STPP is used in food as a preservative and to help retain moisture. It is often added to processed meats and seafood to improve texture and prevent spoilage. You may also find it in dairy products and baked goods.

Health notes

In the U.S., STPP is generally recognized as safe (GRAS) by the FDA for use as a food additive. International bodies like JECFA have evaluated STPP and established acceptable daily intake levels. Some research has explored the potential effects of high phosphate intake on cardiovascular health, but evidence from typical dietary consumption remains mixed.

Allergen info

Sodium tripolyphosphate is not derived from any of the nine major allergens. It does not contain gluten.
