Sodium bicarbonate can be used directly as a raw material in the pharmaceutical industry for the treatment of hyperacidity. It can also be used in film production, tanning, beneficiation, smelting, metal heat treatment, and in the fiber and rubber industries. At the same time, it is used as a detergent for wool, as well as for agricultural seed soaking. One of the most widely used loosening agents in the food industry, used for the production of biscuits, cakes, buns, bread, etc. It is a generator of carbon dioxide in soft drinks; it can be combined with alum as alkaline baking powder or with soda ash for civilian Stone base; can also be used as butter preservative.
Fire-fighting equipment is used to produce acid-base fire extinguishers and foam fire extinguishers. The rubber industry uses it in combination with alum and sodium bicarbonate pore-forming agents to produce uniform pores for rubber and sponge production. Used as a flux for casting steel ingots in the metallurgical industry. Used in the machinery industry as a molding aid for cast steel (sand-turning) sand molds. Printing and dyeing industry is used as a fixing agent for dyeing and printing, acid-base buffer agent, and a rear treatment agent for fabric dyeing and finishing. Adding baking soda to the dyeing can prevent the yarn from generating colored flowers. Used as raw material for antacids in the pharmaceutical industry.
Used as analytical reagents, inorganic synthesis, pharmaceutical industry, treatment of acidemia and food industry, fermentation agent, soda and cold drinks, carbon dioxide generator, butter preservative. It can be directly used as raw material for pharmaceutical industry, detergent for wool, foam fire extinguishing agent, bath agent, alkaline agent, leavening agent. It is often formulated with ammonium bicarbonate as a leavening agent for biscuits and cakes. The added amount in wheat flour is 20g / kg. It can be combined with citric acid, tartaric acid, etc. to prepare the foaming agent of solid refreshing beverage (to produce CO₂).
Because it is a harmless weak alkaline agent, adding about 0.1% to 0.2% when washing vegetables can stabilize the green. When used alone, it is strongly alkaline due to thermal decomposition. It will turn yellow when used in bread and destroy the vitamins in wheat. It is best to use it with acidic substances such as calcium hydrogen phosphate. It can still be used for food blanching and astringency. Because it can increase the pH value, it can increase the water holding capacity of the protein, promote the softening of food tissue cells, and promote the dissolution of astringent ingredients. It has a de-smelling effect on goat milk (the dosage is 10-20mg / kg). As acidity regulator and chemical leavening agent, our country stipulates that it can be used for all kinds of foods that need to add leavening agent.
