Oxygen absorbers, also referred to as oxygen scavengers, are packets containing iron powder. These packets are found in packaged food to maintain the safety of the product and to increase its shelf life. They work by removing or decreasing the levels of oxygen in a package. They are safe to use with food and come in contact with it because the material they are made of lets absorb moisture and oxygen but prevents the iron powder from leaking out.
