Oxygen Absorber Australia
People often ask me, what is the difference between an oxygen absorber and oxygen scavenger?
In respect to small devices that are added to food, and pharmaceutical products, oxygen absorbers, oxygen scavenger are the same thing, just different names for the same thing.
Oxygen scavengers or oxygen absorbers are added to packaging with food or pharmaceutical products, much like silica gel, and then enclosed to modify the atmosphere in the packaging (i.e. remove oxygen to leave nitrogen and carbon dioxide). This leads to improvement of product safety and shelf life extension. A extensive review has been written by Cichello 2015, with the ferrous type being most common, there are many other oxygen absorbers available to cover a wide array of applications and varying in absorption efficiency and speed.
