Is pyrophosphate vegan?

Pyrophosphate is a food ingredient commonly used in processed foods as a stabilizer, emulsifier, and leavening agent. It is a white powder that is derived from phosphoric acid and is chemically known as sodium acid pyrophosphate. It works by reacting with baking soda to produce carbon dioxide gas, which makes baked goods rise. Pyrophosphate is also used to prevent discoloration in processed meats and seafood, as well as to enhance the texture of processed cheeses. However, excessive consumption of pyrophosphate has been linked to an increased risk of kidney disease and other health issues, so it should be used in moderation.
