Oxygen Absorbers 500CC (50 ea.)
Our premium oxygen absorbers remove the oxygen from airtight sealed food storage containers. Removing oxygen stops oxidation, to dramatically extend food shelf life. Eliminating oxygen also prevents all activity by insects even if any are present in the container at the time it is sealed. The absorbers are non-toxic and food safe (the principal ingredients are powdered iron and salt.) Two 500cc packets are sufficient to remove the oxygen from a six gallon bucket completely filled with wheat (or similar grain). Absorbers can be used in containers with any kind of food. If you fill a bucket with a foodstuff that has less density than wheat, then there will be more air in the bucket, so more absorber packets should be used accordingly. (Also note that altitude has a great affect on air density and therefore on the amount of oxygen in a given volume of space. This means if you live on top of a mountain in Colorado, you can get by with somewhat fewer absorbers than average, and if you live at a very low altitude... don't skimp.) Packets are sold vacuum-sealed, in quantity of 50 packets per bag.
Absorption rating: Each absorber is rated at 500cc, which means that each will absorb at least 500 cubic centimeters of oxygen from your storage container, when used as directed. Absorbers are single-use, meaning that once they have absorbed oxygen from a storage container as they're designed to do, they can't be reused.
“Thanks for your great service. When my daughter called to tell me the grinder I'd ordered for her was delivered today, I was amazed.”

Use guidelines: Oxygen absorbers are shipped in an airtight sealed bag. When you open that outer bag, the absorbers soon begin absorbing oxygen from the atmosphere. The absorbers contain enough active ingredient so that you can leave them in the open atmosphere for 30-45 minutes before you seal them into your food containers. Because of this natural working-time limitation, it's important to have your storage containers filled and ready to put the lids onto, before you open the package of 50 absorbers. If you need to use fewer than 50 absorbers and want to save the rest for use later, you can effectively re-seal the extra absorbers in an airtight bag using a home or commercial Vacuum sealing machine. Inside your storage container, oxygen absorbers can be placed under or within food, but we recommend putting them on top so you don't lose track of which containers you've put absorbers into.
Container & lid suitability: If using oxygen absorbers in plastic buckets, you need to use standard hammer-on lids (not Gamma Lids.) Gamma Lids are airtight, but are not designed to counteract the force of pressure that's created when all of the oxygen in the container is removed by oxygen absorbers. Once the standard lid is initially removed to start using the contents, a Gamma Lid can be used to re-seal the bucket against moisture, rodents and insects. A quality bucket and hammer-on gasketed lid will provide a fully adequate oxygen barrier for at least a couple years of storage. For even longer term oxygen-free storage, inside your buckets you can also use Mylar liner bags which, when heat-sealed shut around your food, will effectively block oxygen permeation for years and years.
Shelf life: Absorbers in their original sealed bag have a shelf life of 1 year.

By Amanda4a on 1/5/2019 - Verified BuyerI live in South Carolina, with high humidity. I opened a new bag and used eight absorbers in my flour storage containers. a little over an hour later I walked by the table and felt heat and saw water trickling out from the bag. All of the remaining absorbers had sucked up all the moisture they could.
So, when using vacuum seal closed when done.
I use then all the time in my flour, grains and sugars. With very good results. If the container is opened often, I replace them about every other month. Long term storage once a year.5 out of 5 people found this review helpful. Did you?
By Steven M. in CO on 7/15/2019 - Verified BuyerThanks to all the other reviewers who posted prior to me ----- especially about re-sealing the absorbers before they suck all the moisture out of Colorado. I think these things are going to work out great --- divided up a SuperPail of Hard White Wheat into smaller mylar bags ---- will now be able to use a pound or two of wheat at a time and keep the rest fresh --put a couple of the O2 Absorbers in each small mylar bag and re-sealed the bag with a hot iron --- should work well. Thanks again for all of the help and guidance from Pleasant Hill --- Great company --- like family but without all the yelling.4 out of 4 people found this review helpful. Did you?

By Constance H. in CT on 6/17/2020 - Verified BuyerExcellent product and service. As these are large packages, remember to quickly place unused packs in tightly shut mason jars to keep them viable for later use.1 person found this review helpful. Did you?

By Laura R. in PA on 9/17/2018 - Verified BuyerI have bought from Pleasant Hill Grain many times before and am Never disappointed. The buckets are tall and of excellant quality. The gamma lids make opening the buckets easy and convenient. I have bought elsewhere for other buckets and have come back to Pleasnt Hill for I love their buckets best for storage. The oxygen absorbers help in keeping food products from spoilage or becoming stale. I have also bought storable foods from them. Love them. Will always return to Pleasnat Hill.1 person found this review helpful. Did you?
