Sodium Hexametaphosphate

Sodium hexametaphosphate is a type of phosphate salt. It is a synthetic compound made from phosphoric acid, which is a naturally occurring mineral. It is produced through a chemical process involving heating sodium phosphate.

Manufacturers add sodium hexametaphosphate to foods for several reasons. It acts as a sequestrant, meaning it helps bind metal ions to prevent unwanted changes in color or texture. It also works as an emulsifier to keep ingredients mixed, a texturizer to improve mouthfeel, and a preservative to extend shelf life. It is commonly found in processed meats, dairy products, beverages like iced tea and soda, and some cereals.

In the United States, the Food and Drug Administration (FDA) considers sodium hexametaphosphate to be Generally Recognized as Safe (GRAS) for its intended uses in food. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated phosphates, including sodium hexametaphosphate, and has set an acceptable daily intake. The European Food Safety Authority (EFSA) has also evaluated phosphates and concluded they are safe at current exposure levels from food additives. At typical intake levels from food, it is not associated with adverse health effects.
