Fresherpack 100cc Oxygen Absorbers Pack of 100 for Beef Jerky or Dehydrated Foods

These things are great and work really well. You can see and feel how well they work as the storage bags you are keeping your items in becomes smaller and very rigid as the oxygen is absorbed. The main thing to say is that you must be organised before you start using them. As soon as you open the bag they arrive in they start working so if you don't get them into place quickly they will become exhausted and be of no use. Remember also to seal any unused ones in another bag to preserve them for later use.

Tip, when you open this pack take a sealer bag and put all but 10 in the bag and seal it immediately or the absorbers will be useless. With the 10 use those fast as possible, the open the bag , take another 10 out, seal the main bag and repeat the whole process to keep the absorbers ok.

Very disappointed half if not 3/4 of these were unable useless I even put 5-4 in a jar and milar bag and nothing they didn't work. I will shop somewhere else for them in future.

Great for preparers

You need to be prepared and ready to use these up all in one go as soon as you open the packet.I snipped the corner of the big packet, put one sachet into a container of tomato powder, then put the big packet in the cupboard.Two hours later, I happened to touch the big packet - and it was burningly hot.It seem the sachets were chemically reacting with each other to produce a lot of heat. If I'd left them much longer, I expect the plastic would've melted... or a fire would've broken out.I had to spread the hot sachets across a couple of plates so they were not packed together tightly any more and then they cooled down. But of course they also then spent the night absorbing oxygen from the room, so probably won't work in food now.

Not the same absorbers as the ones imaged (Which i wanted as i have used that kind before and like the clear "DO NOT EAT" sign). The ones I received were all blue with dark blue writing and much harder to notice.

These are the best 100cc oxygen absorbers I have used. Very impressed
