Ammonium Bicarbonate

Ammonium bicarbonate or also known as ammonium hydrogen carbonate is an ingredient used in the leavening or raising for crackers, cookies and biscuits, breads, cakes and many other bakery products.

It is in white powdery crystalline form having a pungent smell and odor of ammonia which stingers in nose and is described as a chemical salt.

Ammonium Bicarbonate chemical formula is NH4HCO3,

Molar Mass 79.056 g/mol,

Density: 1.59 g/cm³,

Melting point: 41.9 °C.

Ammonium Bicarbonate Function in Bakery Food Products

In Biscuits or Cookies Ammonium Bicarbonate is used as a leavening agent or raising agent which helps in puffing of cracker, cookies, biscuits or any baking product.

A leavening agent is any one of a number of substances used in dough and batters that cause a foaming action which lightens and softens the finished product.

When added to dough, they react to produce gases which form the nuclei for the textural development of a biscuit.

Some gases are released by leavening agents CO2, H2O, NH3 and air. Common sources of CO2 are Sodium and Ammonium Bicarbonate.

Ammonium bicarbonate is used in the food industry as an agent. They are used as leavening agents where in application low final moisture content is reached in baked products such as short dough and crackers.

The reaction is: NH 4 HCO3 → NH 3 + H 2 O + CO2

In this reaction ammonia will be baked out provided the final moisture content is low enough and product is thin and porous enough to allow the gas to escape otherwise ammonia may retain in the product and result in off flavour.

For escaping of ammonia during baking puncturing of biscuit is done. Rotating cutter does this. It is used in products that are to be baked to low moisture content. It can also be used in replacement with baking soda or sodium bicarbonate for low-moisture products like dry cookies or some cracker products.

Production of Ammonium Bicarbonate

Ammonium Bicarbonate is artificially Synthesized from ammonium sulfate and calcium carbonate.

Why Ammonium Bicarbonate used in Bakery Products

Ammonium bicarbonate’s usage is restricted to very low-moisture products as even moderate moisture levels will retain the ammonia and render the product inedible. The Moisture Level of Short dough variety biscuits vary from 1 % – 4%, and that for crackers maximum 2%. Therefore, no chances of ammonia trapping in food product.
