Facts on Oxygen Absorbers and How They Work - Country Cooking Recipes

What are Oxygen Absorbers and how do they work?

Oxygen absorbers use a base metal (iron) and a basic chemical reaction (oxidation) to remove and sequester oxygen inside the little packet.  If you open a packet up you will see a dark gray or black substance, which is just powdered iron.  As a packet is used up, the material inside the packet will become a little hard and crunchy, and will turn a reddish brown.

How Many Oxygen Absorbers Should I use?

A general rule of thumb is to use 300-500cc of oxygen absorber per gallon of food you are storing.

A little chart on how that works out:

1 Quart Bag - 100cc oxygen absorber

1 Gallon Bag - 1-2 300cc oxygen absorbers

2 Gallon Bag - 2-500cc oxygen absorbers or 1-1000cc oxygen absorber

5 Gallon Bag - 1-2 2000cc oxygen absorbers or 2-3 1000cc oxygen absorbers
