The Most Often Used Size: 100cc
The most asked question: What oxygen absorber sizes are right for me?
The answer: It depends primarily on what size container you're going to be using to store your dehydrated foods in. 100cc is by far the most often-used in my kitchen.
These Mason jars each contain an oxygen absorber. Look closely at the orange (carrots) jar.
You can just about see the blue and white oxygen absorber!
Oxygen absorber sizes range from 50cc, to 100cc, to 300cc, and to a whopping 2000cc! Why is there such a big size range? When using smaller Mason jars, a 50cc oxygen absorber will suffice.
For a larger quart-size Mason jar, a 100cc size will be fine.
When using the quart-size vacuum-sealer bags - which I recommend you purchase from Amazon, see ads below, I recommend the 100cc oxygen absorber.
The two sizes recommended are thicker bags and don't puncture as easily as the "regular" vacuum-sealer bags. We always add a 100cc oxygen absorber in the bag PRIOR to sealing the bag.
Yes, don't forget to ADD the oxygen absorber into the bag that contains your dehydrated food PRIOR to sucking the air out of the bags!
It's a step easily forgotten in your haste to get to the fun part of using the FoodSaver Food Vacuum sealer!

When storing the vacuum-sealed pouches in bunches for long-term storage, we use Mylar bags. These shiny un-rippable bags are perfect for keeping goodies dry, out of daylight, and away from insects.
When you've put in three or four of your vacuum-sealed packages (that have their 100cc oxygen absorber tucked in each prior to sealing don't forget), we then put these packages inside a Mylar bag. We then pop in a 300cc oxygen absorber into the Mylar bag (along with our dehydrated food packages) and then SEAL the Mylar bag. Do NOT attempt to draw the air out of a filled Mylar bag.
Can't be done. Why? Because both sides of the Mylar bag are smooth, making it difficult, if not pretty impossible, to suck the air out!
The Mylar bag's job with the 300cc oxygen absorber inside it is to protect the three or four packages we have put inside them.
Now comes the part where the 2000cc oxygen absorbers come into play. We only use these whoppers for completely AIRTIGHT bins. No point in putting in a 2000cc oxygen absorber in some bins that do not have snap on lids. If those lids have handles, you can tell by looking closely around their handles that they are NOT really airtight, then DO NOT waste a 2000cc oxygen absorber in it.
So the best way to be absolutely AIRTIGHT is to use feed buckets with lids.
When using the feed-grade buckets, you absolutely can use the 2000cc oxygen absorbers; they're perfect for this as they really ARE air-tight!
