Consumer Advice ​

Calcium chloride is a calcium mineral salt used as a firming agent, calcium fortificant and acidity regulator in food, for example to set tofu, keep canned fruit and pickled vegetables crisp, and add calcium to jellies. Calcium is a mineral naturally present in the body, so it is safe at normal levels; it has a slightly bitter, salty taste, which naturally limits how much can be used before food becomes unpalatable.
