What it is

Sodium tripolyphosphate is a salt made from combining sodium and phosphorus. It is manufactured for use in foods and is a white, granular powder. It is often used to help retain moisture in foods.

Why it's used

Manufacturers add sodium tripolyphosphate to foods to help retain moisture, improve texture, and act as a preservative. It is commonly found in processed meats, seafood, and dairy products.

Health notes

Sodium tripolyphosphate is generally recognized as safe (GRAS) by the FDA for use in food. It is a common ingredient in many processed foods, and studies have not shown adverse health effects at typical consumption levels. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated sodium tripolyphosphate, and the European Food Safety Authority (EFSA) has also assessed its safety. Some research has explored the link between high phosphate intake from processed foods and potential health concerns, but more research is needed to fully understand these associations.

Allergen info

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