Storage Advantage: This product is packaged in a poly bucket which is flushed with Nitrogen. Storing your food in a cool and dry environment, along with nitrogen packing, insures living organisms can not survive and provides a maximum shelf life. Oxygen absorbers are helpful but they can only absorb a set amount of oxygen before the oxygen absorbing chemical expires. Nitrogen will remain in the bucket until it is emptied.
