Oxy-Sorb Oxygen Absorbers for Food Storage, 100cc, 100-Pack

Great!

I started dehydrating food and these were the missing piece I did not know I needed. Threw one in a mason jar with some dehydrated fruit and the lid actually sealed itself which was super cool to watch happen in real time. Just make sure you seal the unused ones back up fast because they start absorbing oxygen almost immediately once you open the bag.

seems to do the job at hand very well

I was watching videos about food dehydrating on YouTube. There was a woman who was super serious about dehydrating. I mean, she was storing her dehydrated food in a vacuumed bag, then put into another vacuumed bag followed by a food storage bucket (that was what she did for the food she was keeping for long term storage.) She placed the O2 absorbers into each bag. The food that she had dehydrated & intended on using sooner instead of later went into Mason jars. She also put the O2 packs ( 1 per quart) into the jars. Then she used a lid & ring, as for canning. The really neat part was, the lid actually sealed because of the O2 absorbers. It really does work because I've tried it. Now I can dehydrate food & it won't get soggy as time goes by. Most of the food I plan on dehydrating will be stored in vacuum sealed bags but the food for immediate use will be stored in Mason jars with O2 absorbers and canning lids & rings. By using the canning lids you can tell if the O2 absorbers are actually working because the bubble in the canning lid flattens & seals the jar. You don't have to seal the jar with the vacuum /sealer. It really works! I noticed many people said their absorbers were junk after opening them. Just make sure to put them into a vacuum sealed bag or jar & they should be fine. Don't leave them loose, exposed to the air. After I opened the bag I removed what I needed & vacuum sealed the rest of the packs. I noticed that the pink indicator turned violet in the few seconds it took to remove 3 packs and seal the remainding packs. Not to worry, the indicator turned pink again after vacuum sealing. I know the packets are still good because several days later I removed a few more O2 absorbers. Again, the indicator turned violet in 5 seconds of air exposure but returned to pink after vacuum sealing. I guess when they no longer seal a Mason jar lid to the jar, then I'll know they aren't good anymore.

Purchased these absorbers maybe two months ago, if that yet keep in jar on closet shelf and still has shelf life...very soft. The size is sufficient, durable, with great absorbency and versatility to use when needed.
