Plain-language explanation

Calcium chloride is a type of salt used as a firming agent, preservative, and to prevent melting in foods like canned vegetables, cheese, and tofu. It is typically produced from neutralizing limestone with hydrochloric acid, but can also be a byproduct of other chemical processes. Major halal certification bodies like JAKIM, MUI, and MUIS consider E509 halal, as the source is mineral and not animal. However, its halal status is guaranteed only if no non-halal substances are used during its manufacturing or processing.
