Sodium Bicarbonate
Product name: Sodium bicarbonate
CAS registry No.: [144-55-8]
Molecular formula: NaHCO3
Molecular weight: 84.00066
Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate), commonly known as baking soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation (Na+) and a bicarbonate anion (HCO3−). Sodium bicarbonate is a white solid that is crystalline, but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate). The natural mineral form is nahcolite. It is a component of the mineral natron and is found dissolved in many mineral springs.
Sodium Bicarbonate Edible Characteristic
Sodium bicarbonate is one of the most widely used bulking agents in the food industry. It is used to produce biscuits, cakes, taro, bread, etc. It is a carbon dioxide generator in soda drinks; it can be combined with alum as an alkaline baking powder, or Soda ash is compounded into civilian stone base; it can also be used as a butter preservative.
Sodium bicarbonate is often formulated with ammonium bicarbonate to make a leavening agent for biscuits and bread. The amount added to the wheat flour is 20 g / kg. A foaming agent (carbon dioxide) for solid refreshing beverages can be formulated with citric acid, tartaric acid and the like. Because it is a harmless weakly alkaline agent, adding about 0.1% to 0.2% when washing vegetables can stabilize green. When used alone, it is strongly alkaline due to thermal decomposition. It will be yellow when used in bread and destroy vitamins in wheat. It is best to use it with acidic substances such as calcium hydrogen phosphate. Can also be used for food blanching, to smell. Because it can raise the pH value, it can increase the water holding capacity of the protein, promote the softening of the cells of the food tissue, and promote the dissolution of the astringent component.
Sodium bicarbonate can be used as an acidity regulator and a chemical leavening agent.
