522. Ammonium carbonate and ammonium hydrogen carbonate (WHO Food Additives Series 17) AMMONIUM SALTS BIOCHEMICAL ASPECTS The principal source of ammonia in the body is the oxidation of glutamate by glutamate dehydrogenase, which is present in liver and other tissues. The levels of ammonium carbonate and bicarbonate in the diet from food additive use are extremely small compared to the levels required to cause physiological changes and pose no toxicological hazard.

carbonate - HighBeam Encyclopedia   (Site not responding. Last check: 2007-10-16) carbonate, chemical compound containing the carbonate radical or ion, CO Most familiar carbonates are salts that are formed by reacting an inorganic base (e.g., a metal hydroxide) with carbonic acid. Magnesium carbonate occurs as magnesite and in dolomite (with calcium carbonate). Iron carbonate is a ferrous compound that occurs in nature as siderite. www.encyclopedia.com /doc/1E1-carbonat.html   (375 words)

Leavening composition for crackers - Patent 4900577 Mixing of the ammonium carbonate with the fermented dough to distribute it substantially uniformly throughout the dough to achieve neutralization of acids produced during fermentation is not disclosed. The use of calcium carbonate to neutralize the acids present in a sponge and to leaven the fermented dough is not disclosed Furthermore, calcium carbonate is not sufficiently soluble in water to uniformly neutralize the acids in a sponge or to leaven a sponge dough substantially uniformly. To ensure uniform distribution of the potassium carbonate throughout the dough, the flour added in the dough-up stage is desirably distributed substantially uniformly over the surface of the mixture formed in the creaming stage and the potassium carbonate is thereafter distributed uniformly over the surface of the flour. www.freepatentsonline.com /4900577.html   (8867 words)

Ammonium carbonate - Wikipedia, the free encyclopedia It possesses a strong ammoniacal smell, and on digestion with alcohol the carbamate is dissolved and a residue of ammonium bicarbonate is left; a similar decomposition taking place when the sesquicarbonate is exposed to air. Ammonia gas passed into a strong aqueous solution of the sesquicarbonate converts it into normal ammonium carbonate, (NH, 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 passes back to ammonium bicarbonate. Ammonium carbonate is used when crushed as a smelling salt. en.wikipedia.org /wiki/Ammonium_carbonate   (218 words)

A New Production Method of Submicron Alumina Powders In this work, ammonium aluminum sulfate is used as a precursor of BAS and biopolymer “chitosan” is used as electrosteric dispersant in the precipitation process to prevent BAS agglomeration.   Ammonium dawsonite is obtained by treating SBA with aqueous ammonium carbonate at 60°C. The compound is characterized by X-ray diffractometry (XRD) and Fourier transform infrared (FTIR) spectroscopy. The ammonium dawsonite was prepared by treating 1.5 g of BAS with 14 ml of AC solution at 60°C for 4h. www.azom.com /details.asp?ArticleID=3455   (1999 words)

Carbonate - Wikipedia, the free encyclopedia In organic chemistry, a carbonate is a salt of carbonic acid. The term "carbonate" is also commonly used to refer to one of these salts or carbonate minerals. At one time, it was thought that the presence of carbonates in rock was unequivocal evidence for the presence of liquid water. en.wikipedia.org /wiki/Carbonate   (560 words)

Molecule of the Day : Ammonium carbonate (Stinky leavening) Ammonium carbonate is analogous to the other bicarbonate and carbonate salts you see - baking soda. The strange thing about the smell of ammonia is that on its own it is quite pleasant in small doses (at least in my opinion) but when it is combined with anything else it smells foul. For instance if you are precipitating protein from fish guts with ammonium sulfate it smells horribly rancid even though the fish is fresh and not bad smelling when you begin. scienceblogs.com /moleculeoftheday/2007/02/ammonium_carbonate_stinky_leav.php   (557 words)
