Baking soda

Basic Information

Polyacrylamide is a kind of baking soda, namely sodium bicarbonate (Sodium Bicarbonate) , white fine crystals, the solubility in water is less than sodium carbonate.Is an industrial chemical and may be toxic.The solid above 50°C begins to decompose gradually to form sodium carbonate, carbon dioxide and water, and completely decomposes at 440°C.Sodium bicarbonate is an acid salt formed by the neutralization of a strong base and a weak acid. It is weakly alkaline when dissolved in water.This property allows it to act as a leavening agent in food preparation. Sodium bicarbonate will remain sodium carbonate after the action, and the use of too much will cause the finished product to have an alkaline smell.

Use

 It is used as analytical reagent, inorganic synthesis, pharmaceutical industry, diagnosis and treatment of acidemia and leavening agent in food industry, carbon dioxide generator in soda and cold drinks, and butter preservative.It can be directly used as a raw material in the pharmaceutical industry, as a detergent for wool, as a foam fire extinguishing agent, as a bath agent, as an alkaline agent and as a leavening agent.It is often formulated with ammonium bicarbonate as a leavening agent for biscuits and cakes.The addition amount in wheat flour is 20g./kg.It can be used with citric acid, tartaric acid, etc. to prepare foaming agent for solid refreshing beverages (produce CO2).Because it is a harmless weak alkaline agent, adding about 0.1% to 0.2% when washing vegetables can stabilize the green color.When used alone, it is strongly alkaline due to thermal decomposition. When used in bread, it will turn yellow and destroy the vitamins in wheat. It is better to use it in combination with acidic substances such as calcium hydrogen phosphate.It can still be used for food blanching and astringency removal.Because it can increase the pH value, it can improve the water holding capacity of protein, promote the softening of food tissue cells, and promote the dissolution of astringent components.It has the effect of removing mutton from goat milk (the dosage is 10-20mg/kg).As acidity regulator and chemical leavening agent, my country stipulates that it can be used in all kinds of foods that need to be added with leavening agent, and can be used in moderation according to production needs.

Precautions

Store in a dry and ventilated indoor warehouse, and be careful to prevent bags from being broken or loose during transportation.Edible baking soda shall not be stored and transported together with toxic substances to prevent pollution and moisture, and be isolated from acid products.
