Calcium Carbonate

 

MF: CaCO₃           MW: 100.09           CAS NO.: 471-34-1

 

Food grade Calcium Carbonate

 

Properties :White fine powder without smell and taste. Its relative density is 2.5-2.7, hardly insoluble in water and enthanol, but soluble in lower density acid.(acetic acid, lower density hydrochloric acid and nitric acid).It is difficult to solubilize in lower density vitriol.

 

Usage:In food industry, it was used as alkaline agent, nutrition supplement agent, the dough regulation agent, solidification agent, yeast foodstuff, resist of lumping agent, loosening agent, fermented agent, glue candy auxiliary agent, modifier, surface colouring agent of food and so on.

 

Packing:In 25kgs net paper or plastic woven bags.
