Calcium Disodium EDTA To Protect Freshness

Calcium disodium EDTA is a synthetic compound used as a food additive. It is made by combining calcium, sodium, and EDTA (ethylenediaminetetraacetic acid). EDTA itself is synthesized from chemicals like ethylenediamine, formaldehyde, and sodium cyanide.

Calcium disodium EDTA is used to protect food freshness by preventing the loss of color and flavor. It works by binding to metal ions, such as iron and copper, which can cause spoilage. It is often found in salad dressings, sauces, and pickled vegetables.

In the U.S., calcium disodium EDTA is Generally Recognized As Safe (GRAS) by the FDA for use as a food additive. It is poorly absorbed by the body and is excreted unchanged. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated it, and neither set a numeric limit (ADI not specified). Some studies have explored its potential health effects, but at typical dietary levels, it is not considered a health concern.
