Raising Agents: Disodium Diphosphate

Disodium diphosphate is a type of phosphate salt that occurs naturally in some foods. It is manufactured by heating sodium acid pyrophosphate, which is produced from phosphoric acid and sodium carbonate or sodium hydroxide.

This ingredient is used as a leavening agent in baked goods like cakes and cookies, helping them to rise and become fluffy. It works with baking soda to produce carbon dioxide gas. It is also used to help retain moisture and improve texture in processed meats and seafood.

In the US, disodium diphosphate is Generally Recognized As Safe (GRAS) by the FDA for use as a food additive. It is also permitted in the EU. Both JECFA and EFSA have evaluated disodium diphosphate and found it safe for consumption at typical levels. Phosphates are naturally present in many foods and are important for bone health, but excessive intake of phosphates from all sources could be a concern for individuals with kidney problems.
