Each pack includes a color-changing indicator dot that shifts from pink to grey if the absorbers have been exposed to air. If the dot is grey upon opening the heat-sealed pack, the absorbers may have lost their potency.

Yes, these are made from FDA food-grade, BPA-free materials and are Kosher certified. They are safe for storing dry goods like grains, beans, and dehydrated foods, but they should not be used with foods that have high moisture content.

Oxygen absorbers begin working the moment they are exposed to air. By packaging them in ten heat-sealed sets, Wallaby ensures that you only expose the amount you need for your current project, keeping the remaining absorbers fresh in their original packaging.

No, these are designed to absorb oxygen, which makes up about 21% of the air. You will still see air volume remaining in the bag after sealing, which is normal and does not indicate that the product is failing.

A 300cc absorber is specifically calibrated for gallon-sized containers. If you are using smaller or larger containers, you may need to adjust the number of packets used to ensure proper oxygen removal.

The active ingredient is iron powder. When exposed to oxygen, the iron oxidizes, effectively pulling the oxygen out of the sealed environment to prevent spoilage and nutrient degradation.
