wisedry300CC [100 Packets, 10 packs of 10 each] Food Grade Oxygen Absorbers for Long Term Food Storage, Keep Food Fresh O2 Absorbers Packets for Wheat Oats Flour and Freeze Dried Foods

Seems like a great product, perfect for adding to any item you don't want moisture to get to. I use them in my ready meal jars.

The 100 oxygen absorbers come in packs of 10 sealed. 10 packs of 10... they seem to work great with the Mylar bags for putting my dehydrated items in.

not a whole lot you can say about these, but I will say this much that everything that I have opened that I’ve used to sell these with is still just as fresh as the day I first sealed them so I say thumbs up

In my inexperience I opened these and did not realize they would react as soon as I did. Place stage all your packs first then open and use asap. Good stuff and works great as dad as I can tell.

Dropped into a nearly heat closed Mylar bag full of dried mashed potatoes then sealed all the way. In a few minutes, the absorbers eliminated the oxygen and a vacuum was created, just as advertised. What was not used, I put in a quart canning jar with a pressure lid and screw lid and some leaking absorber vacuum seale the jar. Hopefully, when I do another long term sealing project, they’ll still be active.

Use them for freeze dry storage,so far so good.

These work very well. They're made from metal shavings. I've bought other OAs made from other materials and they don't last well, even when stored in a vacuum sealed jar.

I wanted to store some rice and beans hoping that it will last for very long time with a Mylar bag with oxygen absorber inside. I heard on the news that there will be food shortage in the near future due to high inflation so I wanted to be prepared. So far I have stored several foods already and hope the dried foods will last with these oxygen absorbers

It was hard to confirm that yhey were packaged in pack of 10 when I got them, and I was abit worried as the bag didnt seem big enough to hold 10 packs of 10, but when I opened the bag to put into my storage box for my 02 absorbers, i did confirm there were indeed 10 packages! Very happy, have't used them yet, and will update my review when I do.

Ok, after reading some of the negative reviews, I feel I have to clear something up. A few people have mentioned that they don’t think the oxygen absorbers are working, because there is no visible sign of their container contracting due to loss of air. This is not how things work. Remember, it is the OXYGEN that is being removed, not the AIR. Oxygen makes up around 21% of air, so your container is not going to behave as if a vacuum has formed within.However, it is important to note that the process of removing the oxygen generates heat within the packets, and this will allow some of the water vapor present in the air within your container to condense. That is why it is important you use a desiccant along with an oxygen absorber.Remember, not all food can be stored with an oxygen absorber. As a general rule, foods with moisture content should never be stored with an oxygen absorber, as there is a very serious risk from dangerous bacteria (botulism). If you are in doubt, do research online.

je l'utilise dans mes bocaux pour conserver la farine, le riz, ou les pates que j'achète en gros.Une fois le sachet inséré dans le bocal, le vide d'air se fait, et lorsque j'ouvre le bocal on entend le pop d'ouverture.je recommande

If your Mason jars don't ping, just wait 24 hours and manually press down the lid center, it will seal just fine . I only get 3-4 pings every 10 jars regardless of the brand I use and they still seal (I test them) so it's totally normal not to get a ping even after a good seal. Condensation is totally normal and common with all brands, don't be alarmed, the moisture will redistribute eventually.These absorbers were well packaged and fresh. I'm very happy with them.

so far used 20 out of 100, very dissapionted, put two in 10 individual mason jars and nothing after 12 hours apart from condensation, i have been canning a long time and use a professional dehydrater so its not a novice mistake, as soon as i opened the factory packet i transfered the 80 odd i never need and vacum sealed it slightly and aging nothing they simply do not work, I will be contacting the company tomorrow about this but very much doubt I will get a replacement so will escalate my issues with amazon, Do not buy these as they release condensation into your bone dry jars full of dried food and will spoil all the effort you have made to preserve your food.
