The most asked question: What size oxygen absorber should I use?

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.

Sizes Range from
50cc to a Whopping 2000cc

Oxygen absorber sizes range from 50cc, to 100cc, to 300cc, and to a whopping 2000cc!

Why is there such a size range?

When using smaller Mason jars, a 50cc oxygen absorber will suffice.

For a larger quart-size Mason jar, then a 100cc size will be fine.

What Size Oxygen Absorber for Vacuum-Sealed Bags?

When using the quart-size vacuum-sealer bags (which I recommend you purchase from DC Sales Enterprises because their bags are thicker and don't puncture as easily as the "regular" vacuum-sealer bags,) use a 100cc 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!

For Mylar Bag Semi- or Long-Term Food Storage, use 300cc

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. THEN these Mylar bags go into plastic lidded bins and buckets for long-term storage.

Mylar bags packed with peas, ready to store away.

For Long-Term Food Storage, use 2000cc in Bins and Buckets

Plastic Lidded storage bins. Good for storing dry goods.

Now comes the part where the 2000cc oxygen absorbers come into play. We only use these whoppers for AIRTIGHT bins. No point in putting in a 2000cc oxygen absorber in some bins that do have snap on lids, but if those lids have handles, you can tell by looking closely around their handles that they are NOT really airtight.

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!
