Sequestrants are substances used primarily in food processing and other industries.
Their main function is to bind with metal ions, such as copper and iron, effectively inactivating them.
This binding process involves forming stable, soluble complex ions.
By sequestering these metal ions, they prevent unwanted chemical reactions, such as oxidation, that can degrade food quality, affecting taste, color, and shelf life.
Therefore, the defining characteristic of sequestrants is their ability to form complex ions with specific metal ions.
