And Sodium Hexametaphosphate

Sodium hexametaphosphate is a synthetic salt made from phosphoric acid, a chemical that occurs naturally in many foods. It is created by heating sodium metaphosphate, which is then cooled and quenched to form the glassy, irregular shards characteristic of this compound. It is often used as a food additive.

Manufacturers add sodium hexametaphosphate to foods to help prevent separation, improve texture, and maintain color. It acts as an emulsifier, keeping oil and water mixed, and as a sequestrant, binding metal ions that can cause spoilage. It is found in products like processed cheeses, syrups, and beverages.

In the U.S., sodium hexametaphosphate is generally recognized as safe (GRAS) by the FDA when used as a food additive. International bodies like JECFA have evaluated it. While generally considered safe at typical consumption levels, some studies have explored its effects on mineral absorption, though evidence is mixed and not conclusive. No specific upper intake limits have been established by major regulatory bodies.
