What is ammonium bicarbonate used for?

Ammonium bicarbonate is widely used in the baking industry due to its bulkiness and stability characteristics and acid regulating ability.

This passage is going to talk about the followings of ammonium bicarbonate:

(1) Introduction to ammonium bicarbonate

(2) The properties of ammonium bicarbonate

(3) Recommendations on ammonium bicarbonate

(1) Introduction to ammonium bicarbonate

Ammonium bicarbonate is a white compound with the chemical formula NH4HCO3. It is in the form of granular, plate-like or columnar crystals with an ammonia smell.

Ammonium bicarbonate is a carbonate, so it must not be placed with acid, because acid will react with ammonium bicarbonate to generate carbon dioxide, which will deteriorate ammonium bicarbonate. However, in rural areas, the ability of ammonium bicarbonate to react with acid is also used. The ammonium bicarbonate is placed in a vegetable greenhouse, the greenhouse is sealed, and the ammonium bicarbonate is placed on a high place, and dilute hydrochloric acid is added. At this time, ammonium bicarbonate will react with hydrochloric acid to produce ammonium chloride, water and carbon dioxide. Carbon dioxide can promote photosynthesis of plants and increase vegetable production, and the generated ammonium chloride can also be used as fertilizer again. Ammonium bicarbonate has an ammonium ion in the chemical formula, which is an ammonium salt, and ammonium salt cannot be placed together with alkali, so ammonium bicarbonate should not be placed with sodium hydroxide or calcium hydroxide.

(2) The properties of ammonium bicarbonate

Ammonium bicarbonate is an inorganic compound, chemically speaking, it is the bicarbonate of ammonium ion.

Due to its physical and chemical properties, this ingredient can be used as a leavening and stabilizer as well as an acidity regulator.

The stabilizing properties of ammonium bicarbonate can maintain ideal physical and chemical properties in food; maintain food homogeneity or maintain/enhance color. In addition, it has the property of adjusting pH by controlling or changing the acidity or alkalinity of food.

Finally, as a leavening agent, ammonium bicarbonate, when used alone or in combination with other substances, has the ability to release gas and at the same time increase the volume of batter and dough of baked goods.

In addition, ammonium bicarbonate can also be used in fire extinguishers, baking powder, quenching baths, and the production of plastics, rubber, dyes, ceramics and pigments. It is also an integral part of cleaning products. In the fertilizer industry, it is used as a source of ammonia.

(3) Recommendations on ammonium bicarbonate

Ammonium bicarbonate and sodium bicarbonate are the most commonly used leavening agents in the baking industry because they release carbon dioxide when they reach a certain temperature and humidity.

Generally, when ammonium bicarbonate is used, it will decompose above 40°C, releasing CO2, H2O and NH3. Add other chemical leavening agents to avoid any residual ammonia in the product.

For ammonium bicarbonate, the Joint FAO/WHO Expert Committee on Food Additives (JECFA) does not specify an acceptable daily intake (ADI) because its use does not constitute a food security risk.

In 1958, China urgently needed to develop the chemical fertilizer industry, and Hou Debang, a chemical expert, successfully developed a new process for producing ammonium bicarbonate. Its characteristic is to combine the production of ammonium bicarbonate with the purification (removal of carbon dioxide) process of the synthetic ammonia feed gas, which is called the combined carbon method for producing ammonium bicarbonate, which simplifies the process, reduces energy consumption, and reduces investment. Through the improvement of the physical properties of ammonium bicarbonate and the continuous improvement of fertilization technology, it has achieved rapid development in China.
