Calcium Chloride is mainly used in the food industry as a food additive, processing aid (in cheese making to correct the calcium content in milk) and as a pickling agent to prevent soaking, fermentation and rotting. It can also play an important role as an acidity regulator, increasing the firmness of fruits and vegetables. Calcium Chloride works perfectly as a flavor enhancer.

In addition to the food industry, calcium chloride can also be found in dietary supplements due to its antimicrobial properties. Calcium Chloride reduces the permeability of blood vessel walls and therefore has antihypertensive, anti-edematous, anti-allergic and anti-inflammatory effects, which are readily used in the manufacture of medicines.

Calcium Chloride is also used to protect stone and wood, to dry gas or to make cotton fabrics non-flammable. In combination with sodium chloride, it is a substance that prevents the formation of ice on the roads.
