EDTA

EDTA, or ethylenediaminetetraacetic acid, is a synthetic compound. It is produced industrially through chemical synthesis.

EDTA is used as a chelating agent, meaning it can bind to metal ions. This property helps prevent metals from causing unwanted changes in food, such as color loss or rancidity. It is often found in dressings, sauces, canned goods, and beverages.

In the US, EDTA is generally recognized as safe (GRAS) by the FDA for specific uses as a preservative and sequestrant. International bodies like JECFA have evaluated EDTA and established guidelines for its use. While generally considered safe at typical food levels, some research has explored its potential effects on mineral absorption, though evidence at common dietary intakes is mixed.
