Oxy-Sorb100-Pack Oxygen Absorber, 100cc

Great!

Oxygen absorbers are self-defined. They absorb oxygen. That's all they do, and that's all they need to do.During the season for many fresh fruits and vegetables, I buy organics at the farmers' markets in quantity and dehydrate them at home for use throughout the off-season. Occasionally, in the past, I have had some of my dehydrated foods spoil due to moisture finding its way into the (supposedly airtight) jars. Since water is two parts hydrogen and one part oxygen, moisture cannot form if either component is missing. Hence oxygen absorbers. I have not had a single failure since I began using them. They're not terribly exciting, but they are effective and I recommend them for anyone who dehydrates foods.Perhaps I oversimplified too much. For water to form in a previously dry area (read "dehydrated" as in water-removed), both hydrogen and oxygen are necessary. When the oxygen is taken out of the mix(as in: absorbed), it leaves only the hydrogen, which cannot turn itself into water. Hydrogen in and of itself is not harmful to food, and being a lighter-than-air gas, it rises until it finds enough oxygen molecules to form water. hw

Just what I needed to keep a lot of my pantry items fresh longer.

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.
