Calcium Disodium EDTA

Calcium disodium EDTA is a synthetic compound that works as a chelating agent. It is made from ethylenediamine, formaldehyde, and sodium cyanide, which are then combined with calcium and disodium. This process results in a stable compound that can bind to metal ions.

Manufacturers add calcium disodium EDTA to food to bind with trace metal ions, which helps prevent spoilage, maintain color, and preserve flavor. It is commonly found in soft drinks, salad dressings, mayonnaise, and canned foods like vegetables and seafood.

In the United States, calcium disodium EDTA is an FDA-approved food additive. JECFA (the Joint FAO/WHO Expert Committee on Food Additives) has evaluated calcium disodium EDTA and set an acceptable daily intake. EFSA (the European Food Safety Authority) has also evaluated its safety. At typical intake levels found in food, it is generally considered safe. While very high doses in animal studies have shown some effects, these are not relevant to normal human consumption levels.
