sequestrant

Ion-capturing chemical compound

A sequestrant is a chemical substance that binds to metal ions, removing them from solution or preventing them from reacting with other compounds.

Sequestrants appear in food preservation, water treatment, and industrial processes: EDTA is a common sequestrant in processed foods.

They prevent discoloration, off-flavors, and unwanted chemical reactions caused by trace metals.
