E530

E530 is the European Union's food additive number for magnesium carbonate. It is an inorganic salt with the chemical formula MgCO3. Magnesium carbonate occurs naturally as the mineral magnesite. In food applications, it is used as an acidity regulator and an anti-caking agent. As an acidity regulator, it helps to control the pH level of foods. Its anti-caking properties prevent powdered food products from clumping together, ensuring a free-flowing texture. Magnesium carbonate is generally recognized as safe by regulatory bodies and is permitted for use in a variety of food categories, including baked goods, dairy products, and confectionery. It is also used in certain pharmaceuticals and dietary supplements as a source of magnesium. The production of food-grade magnesium carbonate typically involves precipitation reactions from magnesium salts. Its presence in food is usually indicated on the ingredient list as E530 or magnesium carbonate.
