Iron powder is widely used as an oxygen absorber. In the last one to two decades, the use of iron powder as an oxygen eater has been accepted well and the customers of it are mainly the enterprises that are making different products that necessarily need to be shielded from oxidation; if the shelf life is to be preserved and denaturing of the product itself is to be avoided. Iron metal powder manufacturers in India cater to the requirements of the food processing enterprises and others to help them improve the shelf life of the packaged products produced by them.
