Hexametaphosphate is a food additive that is commonly used as a sequestrant and emulsifier. It is a white, powdery substance that is added to many food products to improve their texture and stability. Hexametaphosphate is approved for use in food by the FDA and is considered safe when used in accordance with good manufacturing practices.

In food, hexametaphosphate is used primarily as a sequestrant, which means it helps to bind with metal ions to prevent them from reacting with other substances in the food. This can help to extend the shelf life of certain foods, such as canned goods. It is also used as an emulsifier, which means it helps to keep oil and water-based ingredients from separating.

Hexametaphosphate is widely used in the food industry, including in processed meats, dairy products, and baked goods. It is also used in some beverages, such as fruit juices, to prevent discoloration and improve clarity.
