Calcium Disodium EDTA Preservative

Calcium Disodium EDTA is a synthetic compound used as a preservative. It is made by reacting ethylenediamine with sodium chloroacetate, and then neutralizing it with calcium hydroxide. It helps to prevent spoilage by binding to metal ions that can cause oxidation.

Manufacturers add Calcium Disodium EDTA to foods to preserve freshness and prevent discoloration. It is often found in baked goods like cakes, cookies, and pastries, as well as in dressings, sauces, and canned goods. Its ability to chelate (bind) metal ions prevents them from catalyzing oxidation reactions that degrade flavor and color.

Calcium Disodium EDTA is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is also approved for use in other countries. Studies have shown that it is poorly absorbed by the body and is excreted unchanged. International bodies like JECFA and EFSA have evaluated its safety. While generally considered safe at typical consumption levels, some research has explored its potential effects on mineral absorption, though evidence at normal intake levels is mixed.
