Plain-language explanation

Calcium sulphate is a common food additive used as a firming agent, stabilizer, and flour treatment agent, often found in products like tofu, bread, and cheese. It is a naturally occurring mineral, also known as gypsum, or can be synthetically produced from limestone and sulfuric acid. This ingredient is considered halal by major certification bodies as it is an inorganic mineral and not derived from animal sources, so its halal status does not depend on the source.
