Calcium Carbonate (CaCO3

Calcium Carbonate (CaCO3). A mineral salt that occurs in limestone and finds use in yeast foods (q.v.) intended for liquid ferments (q.v.) in which it acts as a buffer (q.v.). It may also serve as the source of optional calcium in enriched flour (q.v.). Its low solubility in water causes it to form a hard scale on interior surfaces of vessels and pipes.
