PackFreshUSA Oxygen Absorbers

Yes, a 2000cc absorber is the standard size recommended for a 5-gallon bucket of dry goods. It provides sufficient capacity to effectively remove the oxygen from the headspace typically found in these containers.

Oxygen absorbers begin working the moment they are exposed to air. Keep any unused packets in an airtight container, such as a vacuum-sealed bag or a small mason jar, to prevent them from activating before you are ready to use them.

While they are highly effective with Mylar bags, they can be used in any rigid container that provides a hermetic seal, such as glass jars or food-grade plastic buckets. The key is ensuring the container is truly airtight so the absorber can successfully pull the oxygen out of the internal environment.

Fresh, active absorbers should feel soft and pliable, similar to a small pouch of powder. If the contents feel hard, lumpy, or like a solid brick, the packet has likely already absorbed moisture or oxygen and should be discarded.

These are designed for dry food storage, such as grains, beans, rice, and dehydrated goods. They should not be used with foods that have high moisture content, as this can create an environment conducive to botulism.
