Main ingredient: Calcium carbonate, chemical formula CaCO₃

 

Features:

Calcium carbonate is an inorganic compound with the chemical formula CaCO?. It is a white fine crystalline powder, tasteless and odorless. It is commonly known as gray stone, limestone, stone powder, etc. Calcium carbonate is alkaline, basically insoluble in water, and soluble in hydrochloric acid. It is one of the common substances on the earth. It is found in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine. It is also the main component of some animal bones or shells. Calcium carbonate is also an important building material and is widely used in industry.

Food grade light calcium carbonate can be used as leavening agent, flour treatment agent, anti-caking agent, acidity regulator, nutritional fortifier, solidifying agent, etc. Our country stipulates that food-grade calcium carbonate can be used in various foods and gum bases that require the addition of puffing agents. Used as flour improver, the maximum usage is 0.03%; milk powder 7.5~18g/kg; soy milk powder and soy flour 4~20g/kg; soft drinks 0.4~3.4g/kg; lotus root starch 6~8g/kg; ready-to-eat breakfast cereals Product 2～7g/kg. When calcium carbonate is used as a leavening agent, it is often used in conjunction with other varieties. The leavening agent obtained by compounding it with sodium bicarbonate, alum, etc., slowly releases carbon dioxide when exposed to heat, making the food produce a uniform and delicate leavening body. It can improve the quality of pastries, bread and biscuits.
