- Typical source

- Plain-language explanation
- Phosphoric acid is a sharp-tasting acid used as a flavoring and preservative in many foods and drinks, especially sodas. It is typically made by reacting minerals with sulfuric acid, a process that does not involve any animal or alcohol sources. Because of this synthetic origin, it is universally considered halal by major certification bodies like JAKIM, MUI, and MUIS.
