Ammonium carbonates: (i) ammonium carbonate (ii) ammonium bicarbonate (E502) – what are they?
Ammonium carbonates are salts of ammonium and carbonic acid. Ammonium carbonate (NH4)2CO3 and ammonium bicarbonate (NH4HCO3), designated E502, are commonly used in the food industry as food additives.
Both compounds are safe for consumption, according to food safety regulations.
Properties of ammonium carbonates
Ammonium carbonates are white, crystalline substances that are soluble in water. Ammonium carbonate is alkaline, while ammonium bicarbonate acts as a buffer, regulating pH. Both compounds are easily decomposed when exposed to heat, releasing ammonia and carbon dioxide.
Uses of ammonium carbonates
Ammonium carbonate is used in the food industry as an acidity regulator, ensuring the taste and texture of products. Ammonium bicarbonate is used as a raising agent in baked goods, adding fluffiness and lightness to cakes, cookies and other confectionery products.
Where to buy ammonium carbonates?
Ammonium 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.
Ammonium carbonates and their functions in food
Ammonium carbonates perform important functions in the food industry, ensuring the proper acidity and structure of food products. Ammonium carbonate regulates pH, while ammonium bicarbonate adds lightness and fluffiness to baked goods. Their safe use is crucial to food quality and shelf life.
