Uses of industrial-grade and food-grade sodium bicarbonate:
1.It can be directly used as a raw material in the pharmaceutical industry, widely applied for treating hyperacidity, and serves as a raw material for antacids. It also has numerous other pharmaceutical applications such as analytical reagents, inorganic synthesis, and treatment of acidemia, boasting an extremely wide range of uses.
2.Applied in film production, tanning, mineral processing, smelting, metal heat treatment, as well as fiber and rubber industries.
3.Wool detergent.
4.Seed soaking agent for agriculture.
5.Its most extensive application is as a leavening agent for making biscuits, pastries, steamed buns, bread and other food products.
