- Plain-language explanation
- E173, or aluminium, is a metallic element used as a food colouring and sometimes as a preservative or anti-caking agent. Aluminium itself is a naturally occurring element and is considered halal by major certification bodies like JAKIM, MUI, and MUIS because it is not derived from animal or alcoholic sources. The halal status does not depend on its source, as it is an inorganic mineral, but it is always best to ensure the final product is certified halal.
