Ammonium carbonate
Ammonium carbonate (additive e503) – the ammonium salt of carbonic acid in life called by liquid ammonia.
Characteristic
By sight additive e503 represents crystals of pink, gray, white colors, or in general colourless, having a characteristic smell of ammonia. Well the rastvorima in water, is unstable in solution and on air. Already at a temperature of 18-25 degrees Celsius begins to emit ammonia and turns into hydroammonium carbonate. And at a temperature of 60 degrees substance breaks up to ammonia, carbon dioxide and water. Actually, release of gases at decomposition of additive allows to use it in the food industry, generally in baking and confectionery instead of yeast.
Receiving ammonium carbonate
For the first time receiving ammonium carbonate came from organic nitrogenous products (hair, nails, horns) under the influence of high temperature by distillation. For today additive e503 is received commercially by heating of mix of chloride ammonium, or as a result of interaction of water with carbon dioxide and ammonia on condition of bystry cooling.
Impact of ammonium carbonate on a human body
According to some informal data additive e503 is potentially unsafe for a human body. Perhaps, harm of additive is connected with high toxicity of ammonia which is formed as a result of ammonium carbonate decomposition. However it is precisely known that in the course of substance decomposition (during preparation of a product) ammonia and carbon dioxide completely disappear, and in finished goods there is only water. So e503 it is possible to call additive harmful to an organism only in the initial state.
Today use of salts of ammonium e503 is authorized practically worldwide.
According to researches of the state agency on food standards of Great Britain (FSA) nutritional supplement e503 is absolutely safe for health of the person.
Ammonium carbonate use
In the food industry additive e503 is used preferential instead of yeast or soda in the baking and confectionery industry. Thus, ammonium carbonate can be met in the following products: bagels, different types of cookies, bakery products, cakes.
In the countries of Scandinavia and northern Europe additive e503 is applied to preparation of branded types of cookies. So, at baking of the Icelandic airy cookies apply only additive e503. If to replace it with yeast or soda, then original cookies will not turn out.
In addition to the food industry ammonium carbonate is used in cosmetics as dye, added to medicines (salammoniac, cough syrups). Also additive e503 is the fermentation accelerator by production of wines and a component of fire extinguishing structures.
