Nedmag Calcium chloride prills food grade (CaCl₂ food) are solid, odourless, white granules. The standard concentration is 96%, and the prills contain less than 0.5% water. CaCl₂ food is mainly used in cheese production as a source for calcium; and in beer bottling where it serves to regulate the hardness of water. CaCl₂ food is also used for canned food, to increase the firmness of the fruits and vegetables. Calcium chloride offers several similar properties as sodium chloride without increasing the sodium content. The product is highly soluble in water by an exothermic reaction, and is hygroscopic (able to attract moisture from air).
