Magnesium carbonates: (i) magnesium carbonate (ii) magnesium bicarbonate (E504) – what is it?
Magnesium carbonates are salts of magnesium and carbonic acid. Magnesium carbonate (MgCO3) and magnesium bicarbonate (Mg(HCO3)2), labeled E504, are food additives used in the food industry.
Both compounds are safe for consumption, and their use is subject to relevant food safety regulations.
Properties of magnesium carbonates
Magnesium carbonates are white, crystalline substances that are soluble in water. Magnesium carbonate is used in the food industry as an acidity regulator and as a raising agent in some confectionery products. Magnesium bicarbonate can be used as an antioxidant and pH regulator.
Uses of magnesium carbonates
Magnesium carbonates are used in a variety of food products. Magnesium bicarbonate is often used as a raising agent in breads, cakes and other baked goods, providing fluffiness and lightness. Magnesium bicarbonate can be used as an acidity regulator in food products such as sodas and canned foods.
Where to buy magnesium carbonates?
Magnesium carbonates are available in grocery stores, both stationary and online, in the food additives section. They can also be found in chemical stores, provided they are intended for use in the food industry.
Magnesium carbonates and their functions in food
Magnesium carbonates perform important functions in the food industry, ensuring the proper acidity, texture and structure of food products. Their safe use is crucial to food quality and shelf life.
