## Overview

Oxy-Sorb 100cc Oxygen Absorbers are food-grade packets designed to reduce oxygen levels inside sealed containers to 0.01% or less, effectively preventing mold and spoilage. Each pack contains 100 absorbers sized for up to 1-quart containers, ideal for Mylar bags, mason jars, and canning. This product extends the shelf life of dry foods and grains, offering a superior alternative to freezing and vacuum sealing for long-term food storage.

## Description

If you're storing dry food for long periods of time and want to keep it free of mold or other contamination, then you need these Oxygen Absorbing Packets from Oxy-Sorb. These absorbers are packets filled with iron powder that oxidize and absorb oxygen when exposed to it. Doing this extends the shelf life of dry foods and grains, as well as keeping those goods free of mold and other pathogens. When used with proper packaging and sealing, including vacuum sealing, the oxygen in the packaging is greatly reduced and you get maximum efficiency. Our absorbers bring the oxygen level down reliably to .01% or less. Whether you're looking to stock up on grains or other dry foods, or to prep them for long term storage, you need these packets. Order now and get the storage and mold-prevention solution that's more effective than freezing and vacuum sealing! Includes 100 packets. Each packet measures 2.26" x 1.36" x 0.14". These are designed to work in up to a 1 quart container.

## Questions & Answers

**Q: These are the 100cc version.  What size container should I use these on?  How do I know what "cc" rating I need to use for my various storage projects**
A: An empty pint canning jar holds about 500 cc of "air" which is about 20% oxygen.  If you have about a pint of "air" in a container that has food in it you would use one of these packets.  The number of packets you use in any container depends on how much "air" you have in the container.  You can improve on this by pulling as much air out of the container as you can so the packet is dealing with less "air" and therefore less oxygen.  If you want to experiment you can put marbles in the container up to the fill line - add water to the top - and pour the water off into a measuring cup to estimate the potential volume of "air" that would be in the filled container without pulling a vacuum in the container.  Using a vacuum device (food sealer, brake line bleeder, vacuum cleaner, etc) will reduce the volume of air in the container and as a result the amount of oxygen will be reduced.A second issue is that under ideal conditions (a sealed glass jar with a strong vacuum in it that is filled nearly to the top with something like flour or rice) if the packet is on the bottom it will take quite a while for what little oxygen that remains to migrate from where ever it is to where the packet is and the stored food will be exposed to small amounts of oxygen during that migration - so I put one near the bottom of the container and one near the top.  I can pack a 1/2 gallon canning jar with pecans so it has around a pint of "air" and than I pull a vacuum in the jar resulting in very little oxygen to begin with.  Two packets is overkill, but overkill works better than under kill.The issue here is that it is the oxygen that makes the food go rancid.

**Q: Can I store the unused ones in a vacuum bag to keep them fresh?  I am going to use these with my powder spices to prevent clumping.**
A: i do store mine in Food Saver bags to keep them fresh.  I make tomato powder and even when using the OA's it still clumps, but the flavor is delicious.  I read some where that silica will stop the clumping.  I don't know if that's true for spices too.

**Q: For coffee lovers: Would these be good to put in with coffee beans to help prolong freshness?  Would like to divide up 5# into 1# amounts, if helpful.**
A: I think this would be fine - if whole beans and not ground, vacuum sealing should keep it fresh 4-6 months, maybe longer.  If you kept the bags in the freezer, that might extend your time even more.  But it's tricky, as there are oils in the beans so they can go rancid if it isn't done properly.  Good luck!

**Q: I see they can't be frozen apparently but what happens if I've already put some in the freezer with some dehydrated and vacuum sealed food? Ruined?**
A: I have been researching on your question and I can't find the answer. I have put dehydrated and vacuum sealed food in the freezer but I have never used an absorber with them. Sorry I could not help you. Sounds like a question for me to know too. Hope you find the answer. Carrissa

### ⭐⭐⭐⭐⭐ *** IMPORTANT *** After opening *** MUST PUT IN AIR TIGHT CONTAINER IMMEDIATELY ***
*by C***A on December 16, 2012*

Bought a dehydrator for the first time had no clue how to use these packets. I opened the package, not knowing that you have to put it immediately back into an airtight container again. Went to google how to store dry foods on the internet - when I came back, the whole bag was warm! I panicked and thought I was going to burn the house down - or, that it might explode! I am not a chemist and have long forgotten anything I've ever learned from high school. Had to go back and google how to use these things! I wish the package had large warning labels, or IMPORTANT PLEASE READ instructions in the box - if it did, I didn't see it. I need bifocals and couldn't read whatever little prints are on the package. Now, am not too certain if they're still good or not. I used a few with some dry cereal and i heard the jars pop and seal. Am glad to learn about these handy little packs though, will find them most useful. Since my sweetie died I've had more time to think about things that I've taken for granted all our life. I guess we were out enjoying out lives too much and didn't realize this as an option. I'm looking forward to dehydrating oranges, bananas, fruits, vegetable chips, jerky, herbs and teas; of course for storing my sugar, flour, rice beans. Over all my 30+ married life, have thrown away so much food because never stored anything properly. Flour would sit on my shelf that I would use once or twice - then, it would taste horrible after several months of non-use, I end up throwing it all away. This should preserve the life of my dry foods much longer. A much appreciated product that I wish I'd of used years ago! Looking forward to canning and preserving more foods throughout the rest of my life.

### ⭐⭐⭐⭐⭐ Keeps moisture from ruining your dried foods
*by H***T on December 17, 2010*

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

### ⭐⭐⭐⭐⭐ Remember to store them in an air-tight container
*by M***E on September 14, 2016*

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.
