Ammonium bicarbonate General Description
AMBIC is a  white crystalline solid having the odor of ammonia. 
AMBIC is soluble in water. 
The primary hazard is the threat to the environment. 
Immediate steps should be taken to limit spread to the environment. 
AMBIC is used to make other ammonium compounds, in food processing, and for other uses.

The powdered baking ammonia cannot be used for bulky baked foods; however, Ammonium bicarbonates applications are not only bounded to the food industry. 
Ammonium bicarbonates use can found in the agricultural, pharmaceutical, textile, and ceramic industries, among others. 
Ammonium bicarbonate has bestowed the new entrants and emerging players with lucrative opportunities and untapped new avenues for them.

Ammonium bicarbonate is a common leavening agent used in the baking industry and has been reported to be used in Guangdong.style steamed breads. 
Ammonium bicarbonate releases carbon dioxide and ammonia gas when the dough temperature reaches 40°C. 
If AMBIC is used at the correct addition rate, Ammonium bicarbonate significantly improves steamed bread color and volume. 
In addition, Ammonium bicarbonate can function as a buffering agent. 
Overuse of ammonium bicarbonate can result in ammoniacal taints in the final steamed bread. 
Ammonium bicarbonate is more commonly used in low.moisture products such as English.style biscuites.

Applications of AMBIC
Ammonium bicarbonate (AMBIC) was used in the following studies:
To derivatize histone proteins from human monocyte.derived macrophages (MDM) by propionylation.
Destaining of silver.stained proteins in polyacrylamide gel bands during the peptide mass profiling using a mass spectrometer.
Digestion of proteins isolated from Xenopus egg extracts in coomassie blue.stained gel bands during the analysis of microtubule.binding proteins.

AMBIC is used in, for example, Swedish "drömmar" biscuites and Danish "brunkager" Christmas biscuites, and German Lebkuchen. 
In many cases Ammonium bicarbonate may be replaced with baking soda or baking powder, or a combination of both, depending on the recipe composAmmonium bicarbonateion and leavening requirements.
Compared to baking soda or potash, hartshorn has the advantage of producing more gas for the same amount of agent, and of not leaving any salty or soapy taste in the finished product, as Ammonium bicarbonate completely decomposes into water and gaseous products that evaporate during baking. 
Ammonium bicarbonate cannot be used for moist, bulky baked goods however, such as normal bread or cakes, since some ammonia will be trapped inside and will cause an unpleasant taste. 
AMBIC has been assigned E number E503 for use as a food additive in the European Union.

Production of Ammonium bicarbonate
Ammonium hydrogen carbonate is obtained by combining carbon dioxide (CO2) and ammonia (NH3):

AMBIC is commonly used as an inexpensive Ammonium bicarbonaterogen fertilizer in China, but is now being phased out in favor of urea for quality and stabilAmmonium bicarbonatey. 
This compound is used as a component in the production of fire.extinguishing compounds, pharmaceuticals, dyes, pigments, and Ammonium bicarbonate is also a basic fertilizer, being a source of ammonia. 
Ammonium bicarbonate is still widely used in the plastics and rubber industry, in the manufacture of ceramics, in chrome leather tanning, and for the synthesis of catalysts.
Ammonium bicarbonate is also used for buffering solutions to make them slightly alkaline during chemical purification, such as high.performance liquid chromatography. 
Because AMBIC entirely decomposes to volatile compounds, this allows rapid recovery of the compound of interest by freeze.drying.
Ammonium bicarbonate is also a key component of the expectorant cough syrup "Senega and Ammonia".

A white powder made for use as a leavening agent which is added as an ingredient when preparing many different types of baked goods that will have thin shells or crusts such as puff pasteries, flat breads, crackers, and some cookies. 
Ammonium Biocarbonate is typically used with smaller baked goods that can quickly disperse and evaporate the ammonia gas as Ammonium bicarbonate builds up within the baked Ammonium bicarbonateem. 
During the baking process, an ammonia aroma may be present, but Ammonium bicarbonate will not remain and will not be noticed in the baked goods when they are eaten. 
The result of using Ammonium Bicarbonate is a baked good that will have an light, airy, crispy, and somewhat fluffy texture. 
The term Ammonium Bicarbonate is actually an old term that is now more commonly referred to and replaced in recipes Ammonium bicarbonateh the substance known as baking powder or baking soda. 
However, the use of actual Ammonium Bicarbonate substance is still preferred by some who want a lighter or crispier texture than can be achieved by using baking powder or soda.

When properly stored in a cool dry area, Ammonium Bicarbonate can last for several years. 
If stored in a warm or damp area where air can reach the powder, this substance begins to clump together as the particles go through a chemical reaction, which will affect the flavor adversely when baked goods use the air.exposed Bicarbonate. 
In addition, when exposed to air, the Ammonia may begin to evaporate from the powdered Bicarbonate substance. 
When a recipe suggests the use of Ammonium Bicarbonate, equal amounts of baking powder can be substituted if necessary. 
To determine if Bicarbonate is still active, add a spoonful of the powder to a cup containing lemon juice or vinegar and see if Ammonium bicarbonate fizzes. 
Stale AMBIC will be flat and will not fizz when combined with the vinegar or lemon juice.

Ammonium bicarbonate will decompose during baking and release ammonia and carbon dioxide leavening gases without reacting with a leavening acid. 
Unlike sodium bicarbonate, which leaves a residue of alkaline sodium carbonate, ammonium bicarbonate leaves no residue when Ammonium bicarbonate decomposes by heat. 
Ammonium bicarbonate, therefore, has no effect on the pH of the baked product. 

If there is more than about 5% moisture in the baked product, however, the ammonia gas will dissolve in this water and impart an ammoniacal flavor to the product. 
For this reason, ammonium bicarbonate is used only in low.moisture products such as crackers.
Ammonium Bicarbonate (or baking ammonia or hartshorn salt) is used as a leavening agent in baking of cookies and other edible treats. 
AMBIC gives an explosive and fast leavening for baked goods that are baked for a short time. 
Ammonium bicarbonate is specially suitable for thin, dry cookies. 

When heated Ammonium bicarbonate releases ammonia and carbon dioxide gases, but no water. 
The lack of water allows the cookies to cook and dry out faster.
AMBIC may also be used as a substitute to remove the alkaline.like flavor that at times occurs in some baked goods when baking powder or baking soda is added. 
Many older European and Scandinavian recipes may use the term Baker's Ammonia instead of Ammonium Biocarbonate when referring to this substance. 

Ammonium bicarbonate is also often referred to as Hartshorn or Harts Horn which is a substance that is removed from deer antlers. 
Ammonium bicarbonate is important to understand that Ammonia and leaving agents such as Baker's Ammonia, baking powder or baking soda are not the same as household ammonia which is a poisonous substance and should not be used with foods or baked goods.
AMBIC is activated when Ammonium bicarbonate is added to a dough or batter mixture and warms to room temperature or is baked, since heat is the catlyst to activate the chemical reaction and the gases. 
The chemical reaction releases an ammonia gas that causes the baked goods to rise. 
Ammonium Biocarbonate should be stored in an airtight sealed container such as a glass jar with an airtight lid. 

If you don't store AMBIC in an airtight jar Ammonium bicarbonate will evaporate. 

Ammonium bicarbonate is an inorganic chemical compound which is usually used as a raising or leavening agent in the food industry. 
AMBIC is utilized as a source of carbon in low.moisture baked foods. 
Ammonium bicarbonate is generally produced by coursing the carbon dioxide through a stream of aqua ammonia. 
The result of the reaction is unstable and thus Ammonium bicarbonate is kept in a cold atmosphere.

Ammonium bicarbonate can release ammonia and carbon dioxide, leavening gases without reacting with a leavening acid. 
Ammonium bicarbonate spontaneously decomposes into this ingredient and ammonia first and in a later step into ammonia and carbon dioxide gas:
Baking soda can replace this ingredient in low.moisture products like dry cookies or some cracker products although this may not reproduce the unique texture.

Ammonium bicarbonate is listed in Old World baking recipes. 
Especially, in Scandinavian gingerbread, Polish ammonia cookies and tranditional German Spekulatius Christmas cookies.

Ammonium bicarbonate is an inorganic salt commonly used in the food industry. 
Ammonium bicarbonate can be generated by the interaction of gaseous carbon dioxide and aqueous ammonia.

Advantages of using this in baked goods include:
The absence of alkaline taste residue often encountered with sodium bicarbonate
Ammonium bicarbonate doesn’t affect the pH of the baked goods
In high moisture baked goods (in excess of 5%), ammonium bicarbonate may lead to the development of ammoniacal flavor. 
This is why Ammonium bicarbonate’s most suited for low.moisture products such as biscuites, crackers, cookies, and waffle cones.

Typically, this ingredient is mixed in with the liquid ingredients to ensure Ammonium bicarbonates dissolution prior to incorporating into the dry mix. 
In some formulas, Ammonium bicarbonate is used in combination with 30.50% baking soda.

Ammonium hydrogen carbonate
Other names
Bicarbonate of ammonia, ammonium hydrogen carbonate, hartshorn, AmBic, powdered baking ammonia

Ammonium bicarbonate is produced by combining carbon dioxide and ammonia:
CO2 + NH3 + H2O → (NH4)HCO3
Since ammonium bicarbonate is thermally unstable, the reaction solution is kept cold, which allows the precipitation of the product as white solid. 
About 100,000 tons were produced in this way in 1997.
Ammonia gas passed into a strong aqueous solution of the sesquicarbonate (a 2:1:1 mixture of (NH4)HCO3, (NH4)2CO3, and H2O) converts Ammonium bicarbonate into normal ammonium carbonate ((NH4)2CO3), which can be obtained in the crystalline condition from a solution prepared at about 30 °C. 
This compound on exposure to air gives off ammonia and reverts to ammonium bicarbonate.

History of Ammonium Carbonate
Hirschhornsalz was made in the Middle Ages by burning or dry distillation of keratin.containing materials (keratin is a structural protein found in the animal kingdom). 
They did this by heating shredded horns, hooves, antlers, skin, and even decomposed primate urine in lime kilns (Kalköfen), which were ovens built for heating limestone (calcium carbonate). 
This is a manufacturing process which goes back to Greek and Roman times to make quicklime, a building material. 

The residue was collected after the ovens cooled off. 
Since wood ash was often boiled in water and used as a leavening agent, Ammonium bicarbonate is possible that these ashes were used in the same way.
Hartshorn was used to treat diarrhea, dysentery, fevers, and many different types of bites. 
The name was of particular importance in the Middle Ages when people believed that the salt collected from burning particular parts of the animal had special, medicinal value. It was a common smelling salt in Victorian times.

Production and Chemistry
Today, the white powder is chemically produced by heating ammonium chloride or ammonium sulfate with chalk. 
Hirschhornsalz is a mixture of three molecules:

Ammonium carbonate (NH4 )2CO3 → 2NH3 + CO2 + H2 O
Ammonium bicarbonate NH4 HCO3 → NH3 + CO2 + H2 O
Ammonium carbonate (second form) NH4 NH2 CO2 → 2NH3 + CO2
These molecules break down into the gases ammonia, carbon dioxide, and (water) steam when heated to 140 F (60 C) or higher. 
The gases lift the dough or batter (which has air bubbles in Ammonium bicarbonate through creaming) before the batter is set as they rise towards the surface of the cookie. 
As the dough sets up, the bubbles remain but the ammonia, carbon dioxide, and steam are dispersed from the baked good and into the air in the kitchen.
Baker's ammonia can react with certain sugars and amino acids in the dough to make small amounts of acrylamide, a carcinogen.

Alternate Spellings

E503ii (EU food additive)
Baker's ammonia
Hart's horn
Bicarbonate of ammonia
Ammonium hydrogen carbonate
Powdered baking ammonia, bicarbonate salt of ammonia
Salt of hart’s horn

Ammonium bicarbonate is a white crystalline powder used in flat, spiced cookies, such as gingerbreads, and in eclair paste. 
Ammonium bicarbonate must be dissolved in the cold liquid portion of the batter. 
At room temperature, decomposition of CO2 in the batter is minimal. 
When heated to approximately 60°C (140°F) decomposition is more noticeable, and at oven temperature, decomposition takes place in a very short time. 
Ammonium bicarbonate should only be used in low moisture.containing products that are not dense. 
Providing that these conditions are met, there will be no taste and odour remaining from the ammonium.

Ammonium carbonate is a salt with the chemical formula (NH4)2CO3. 
Since Ammonium bicarbonate readily degrades to gaseous ammonia and carbon dioxide upon heating, Ammonium bicarbonate is used as a leavening agent and also as smelling salt. 
Ammonium bicarbonate is also known as baker's ammonia and was a predecessor to the more modern leavening agents baking soda and baking powder. 
Ammonium bicarbonate is a component of what was formerly known as sal volatile and salt of hartshorn.

Ammonium carbonate is used for leavening in cookies, flat biscuites, or crackers. 
In German baking, Ammonium bicarbonate's known as hirschhornsalz or hartshorn, and Ammonium bicarbonate is also called baker's ammonia. 
Ammonium bicarbonate is not used for cakes since the gaseous ammonia given off during baking cannot escape the thicker, higher batters and would make the baked goods smell bad. 
Ammonium bicarbonate leaves no salty or soapy taste residue as baking powder sometimes does since Ammonium bicarbonate completely decomposes into ammonia and carbon dioxide.

What is Ammonium Bicarbonate?
Ammonium Bicarbonate appears as a white crystal or crystalline powder. 
Ammonium bicarbonate volatilizes rapidly at 60 °C, dissociating into ammonia, carbon dioxide, and water, but Ammonium bicarbonate is quite stable at room temperature. 
One gram dissolves in about 6 ml of water.

In chemistry, the word ‘bicarbonate’ is inaccurate and outdated. 
Ammonium bicarbonate was first coined in 1814 by a chemist who observed that there is twice as much carbon as sodium in sodium bicarbonate.
After different types of bicarbonates were identified, with different ratios, the observation became irrelevant, but the habAmmonium bicarbonate lives on.

Bicarbonates are the main form of dissolved inorganic carbon in the ocean. 
In freshwater plants, bicarbonates are released into the water as part of photosynthesis. 
Bicarbonate can shift the water’s pH to toxic alkaline levels. 
Bicarbonate continues until nightfall, when photosynthesis stops and respiration releases carbon dioxide, causing pH to return to normal. 
Bicarbonates commonly act as pH buffers in the human body [plop, plop, fizz, fizz] and in soil.

Ammonium bicarbonate was used in things like cookies because Ammonium bicarbonate did not impart a bitter taste the way some early version of baking soda and powder did. 
The ammonia gas gets trapped in baked goods like a cake where Ammonium bicarbonate cannot escape and will make the cake smell bad, so Ammonium bicarbonate is only used in cookies that are flat and porous where the surface area allows to ammonia to disappear. 

Ammonia powder is ammonium bicarbonate, a leavening agent that is a precursor of today's baking powder and baking soda; Ammonium bicarbonate must be ground to a powder before using. 
Ammonium bicarbonate is also known as hartshorn, carbonate of ammonia or powdered baking ammonia. 
Ammonium bicarbonate is still called for in some recipes especially for cookies.

Origin and Commercial Production
Historically, ammonium bicarbonate was produced in Northern Europe from dry distillation of hair, horn or other nitrogenous organic matter. 
Today, Ammonium bicarbonate is produced commercially by dissolving carbon dioxide in ammonia:

Ammonium bicarbonate (NH₄HCO₃) has been shown to contribute, promote, and speed up acrylamide formation in baked products. 
A proposed mechanism is that NH₄HCO₃ fragments sugars, forming the highly reactive glyoxal and methylglyoxal species, which can react with asparagine, thereby increasing acrylamide levels.
Ammonium bicarbonate (ABC) is an important raising agent for the biscuit and cracker industry and bakers also use Ammonium bicarbonate in some strongly flavored products like gingerbread. 
ABC decomposes on heating at 60°C in a temperature.driven reaction releasing carbon dioxide, ammonia, and water vapor. 
ABC offers major technical benefits, as Ammonium bicarbonate is used for rapid, early expansion in the oven. 

Since ABC does not start acting before the oven, Ammonium bicarbonate means that products do not gas when the dough is mixing or standing which can be important during plant breakdowns. 
Biscuit makers also value the consistent stack height Ammonium bicarbonate gives, and Ammonium bicarbonate leaves no residue and no adverse flavors in low moisture products. 
Another complexity revolves around the fact that the level added to a recipe may change daily because of normal raw material variations. 
In this situation using ABC allows the adaptation of only one, stand.alone, ingredient, whereas other raising agents—that require acids for their action—would be more complicated to adapt. 
Unfortunately, the tendency to promote acrylamide formation is now a major drawback of using ABC.

Ammonium bicarbonate dissolves in water to give a mildly alkaline solution. 
Ammonium bicarbonate is insoluble in acetone and alcohols.

Ammonium bicarbonate decomposes above about 36 °C into ammonia, carbon dioxide, and water in an endothermic process and so causes a drop in the temperature of the water:
NH4HCO3 → NH3 + H2O + CO2.

When treated with acids, ammonium salts are also produced:
NH4HCO3 + HCl → NH4Cl + CO2 + H2O.
Reaction with base produces ammonia.

Formula and structure: The chemical formula of ammonium bicarbonate is NH4HCO3. 
Ammonium bicarbonates molecular formula is CH5NO3 and Ammonium bicarbonates molar mass is 79.056 g/mol. 
Ammonium bicarbonates chemical structure consists of the ammonium cation (NH4+) and the bicarbonate anion (HCO3.).
Occurrence: Ammonium bicarbonate is present in small quantities in nitrogenous organic matter, along with other ammonium salts.
Preparation: Ammonium bicarbonate is produced by passing carbon dioxide gas into aqueous ammonia until the ammonium bicarbonate crystals are formed, which are then separated from the solution by filtration or centrifugation. 
To prevent decomposition of the product, the reaction is performed at cold temperatures.
CO2 + NH3 + H2O → NH4HCO3

Ammonium bicarbonate reacts with sulfates of alkaline.earth metals precipitating their carbonates:
CaSO4 + 2 NH4HCO3 → CaCO3 + (NH4)2SO4 + CO2 + H2O.

Ammonium bicarbonate also reacts with alkali metal halides, giving alkali metal bicarbonate and ammonium halide:
NH4HCO3 + NaCl → NH4Cl + NaHCO3;
NH4HCO3 + KI → NH4I + KHCO3;
NH4HCO3 + NaBr → NH4Br + NaHCO3.
Natural occurrence
The compound occurs in nature as an exceedingly rare mineral teschemacherite.
