Is soda food grade the same as industrial grade


Soda ash is widely used in food industry, medicine and veterinary medicine, but it is widely used as animal feed additive abroad. Main uses: chemical reagent, inorganic synthesis, medicine, tanning, food, spinning, dye industry, fire extinguishing agent, detergent, pesticide. It can be used as fermentation agent in food industry, carbon dioxide generator in soda and cold drink, and butter preservation agent. It can be directly used as raw material for pharmaceutical industry. It is also used in film making, tanning, mineral processing, smelting, metal heat treatment, fiber, rubber and agricultural seed soaking. It is also used as detergent and foam extinguishing agent for wool.

 

Soda ash is an important chemical raw material with large tonnage. Soda production includes Solvay method, Hou’s method and natural soda processing method. The raw materials used vary with the processing methods. The main raw materials are raw salt (including sea salt, pond salt, mineral salt and underground brine), natural alkali, limestone, ammonia, etc.

 

The supply and demand of soda ash are determined by the capacity and operating rate of soda ash and its downstream industries. The downstream of light alkali and heavy alkali are different and rarely mixed. Within the range of heavy quality, soda production enterprises can adjust the output ratio of light alkali and heavy alkali according to the price and demand of light alkali. It is used in food industry as neutralizer and leavening agent, such as making amino acids, soy sauce and flour products, such as steamed bread and bread. It can also be added into pasta to increase elasticity and ductility. Sodium carbonate can also be used to produce monosodium glutamate.
