ammonium bicarbonate
carbonic acid monoammonium salt
Used in foods as an alkali, dough strengthener, leavening agent, pH control agent and texturizer Ammonium bicarbonate is an irritant to the skin, eyes and respiratory system. Ammonium bicarbonate from China used to make cookies was found to be contaminated with melamine, and imports banned in Malaysia in the 2008 Chinese milk scandal.; At room temperature, ammonium bicarbonate is a white, crystalline powder with a slight odour of ammonia that can dissolve in water to give a mildly alkaline solution. It is however insoluble in acetone and alcohols. Ammonium bicarbonate decomposes at 36 to 60 °C into ammonia, carbon dioxide and water vapor in an endothermic process (as it is with many ammonium salts) and so causes a drop in the temperature of the water. When reacted with acids, carbon dioxide is produced, while reactions with alkalis give ammonia.
