Oxygen Absorber Sizes

100cc Oxygen Absorbers, 100-pk shown

"What oxygen absorber sizes are right for me?" is a question I'm often asked.

My answer: It depends on what size container you're using to store your dehydrated foods in.

The Most Often Used Size: 100cc

But the 100cc size is by far the most often used in my kitchen when I'm storing my dehydrated foods. Read more about what Oxygen Absorbers are here.

Yes, see the chart below in the pink shaded box below these FAQs.

Oxygen absorbers for dried fruit and vegetables?

Yes, they're ideal for dried fruit and veggies, and:

  • Flour, sugar, salt
  • Nuts, seeds
  • Dried fruits
  • Dehydrated vegetables

Our dried food items need to already be very low moisture content to prevent absorbers from getting overwhelmed. Absorbers also require an airtight environment to work properly. By regulating oxygen and condensation, they effectively achieve a good balance keeping our dried food safe.

So any dried goods destined for your pantry or emergency food storage bins and buckets benefit greatly from using oxygen absorbers before sealing them away, significantly lengthening freshness.

Where to buy oxygen absorbers?

I get mine from Amazon. Why? Because of their fast delivery, plus, they wouldn't be allowed to sell them on Amazon if they sold "duds."

Having said that, you can return a "stale" package if it arrives with a PURPLE-colored pill inside it. That "freshness indicator pill" should still be PINK upon arrival. Read more here.

Oxygen absorbers are readily available in different sizes, such as 50cc, 100cc, 300cc, and 2000cc.

The reason for different sizes depends upon what size container your dehydrated foods are going to be placed in.

If you're using a small (half-pint) jar, use a 50cc oxygen absorber.

For a quart-sized jar or food vacuum sealer bag, use a 100cc oxygen absorber.

For a 10" x 14" Mylar bag, use a 300cc oxygen absorber.

For storage bins or buckets with lids, use a 2000cc oxygen absorber.


In the image above, the left-hand bag is a full unopened 100cc package of 100 oxygen absorbers. The pink oxygen absorber pill is visible, noted by the red arrow.

The packages to its right are my homemade packages of 20 - made from a newly-opened package.

When I need oxygen absorbers I grab one of my homemade packages, trim off the top seal, take out what I need, and immediately reseal it. The small package at the top of the unopened package (on the left side of that image) is what remains after working my way down one of my homemade packages!

By making small packages of 20, you'll extend the life of your newly opened 100-package and end up with sealed bags of 20 each. (Five packages!)

Ideal for At-Home Food Storage & Preservation

We use oxygen absorbers for food storage and preservation for the following reasons:

  • Removes oxygen - They absorb any residual oxygen left in packaged containers, creating an anaerobic environment that inhibits food spoilage.
  • Prevents oxidation - Absorbing oxygen prevents oxidation that leads to loss of nutrients, color changes, rancidity, and growth of aerobic bacteria. This prolongs shelf life.
  • For dry foods - They prevent stale flavors, bugs, and rancidity in stored grains, beans, dried fruits, nuts, coffee, spices, and other dry goods.
  • In Mylar bags - Oxygen absorbers are often used in Mylar bags to remove oxygen when packaging bulk foods for long-term storage.
  • Dehydrated foods - They help retain nutrients and prevent oxidation in dehydrated fruits, vegetables, and meats.
  • Environmentally friendly - Oxygen absorbers reduce food waste by keeping home-preserved foods fresh for longer periods.

Two quart-sized jars, and one half-pint-size Mason jar.

Oxygen Absorber Sizes Range From 50cc to 2000cc!

These Mason jars in the above image each contain an oxygen absorber.

If you look closely you can see the blue and white oxygen absorber packet on top of the dried carrots and the dried green beans (the tall jars).

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

Why is there such a big size range? (See the pink chart at the top of the page).

  • When using smaller Mason jars, a 50cc oxygen absorber will suffice.
  • For a larger quart-size Mason jar, use a 100cc size.
  • The 300cc oxygen absorber is what I add to Mylar bags - along with your vacuum-sealed dried food packages of course - before sealing the Mylar bag. (We don't vacuum the air out of Mylar bags).
  • The 2000cc oxygen absorbers are for use in the lidded food-grade buckets and/or plastic lidded bins (airtight variety). These are for "serious" long-term food storage purposes.

I have noticed that a 400cc oxygen absorber is also available on Amazon which you could use instead of a 300cc oxygen absorber.

Both the 300cc and 400cc sizes work well for Mylar bags!

Reminder: Oxygen Absorber Sizes to Use for Vacuum-Sealer Bags

When using the quart-size vacuum-sealer bags—which you may purchase from Amazon (see their image ads below), add the 100cc oxygen absorber into your vacuum-sealer bag before drawing the air out.

Amazon has different oxygen absorber sizes available (as you might have guessed! Amazon has everything...)

The quart- and pint-sized bags (shown below) are the FoodSaver brand food vacuum-sealer bags. They are safe for raw or cooked foods. They are also freezer, refrigerator, microwave, and boil safe!

Remember, we always add a 100cc oxygen absorber in the bag BEFORE drawing out the air and sealing the bag that contains your dehydrated goodies.

It's a step easily forgotten in our haste to get to the fun part of using the FoodSaver Food Vacuum sealer.

Have the kids help with this part of the dehydration and storage process.  They think the noise from the vacuum sealer is fun... (and it is!)

Mylar bags packed and sealed

Use a 300cc Size Oxygen Absorber for Mylar Bags which are Ideal for Short- or Long-Term Food Storage

When storing the vacuum-sealed pouches 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. I can fit about 3 or 4 vacuum-sealed pouches in one Mylar bag.

Your vacuum-sealed packages with their 100cc oxygen absorber tucked in each (before air removal and sealing, don't forget) - are now ready to be placed 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! See the "A Side Note" below.

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.

The 'Inside Story' of a
food vacuum sealer bag:

Let's Take A Closer Look...

Look closely at the plastic vacuum bags that the dehydrated food goes into first; you'll notice that one side is smooth and the other side is 'bumpy', for want of a better word.

These textured 'bumps' enable the air to be drawn out of the bag, otherwise, the two smooth surfaces just simply clamp shut tight together! Yeah, repeating myself here, but ... just want to get the point across!

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

Now comes the part where the 2000cc oxygen absorbers come into play. We only use these whoppers for completely AIRTIGHT bins. There is no point in putting in a 2000cc oxygen absorber in the plastic bins that do not have airtight snap-on lids.

If those bins' lids have handles like the one shown in the image, you can tell by looking closely around their handles and "hinges" that they are NOT airtight at all. Nor were they designed to be, in their defense.

Having said that, I DO use them to store Mylar bags that have been filled with dehydrated goodies. I keep the bins in my closet, so they don't face temperature extremes or bugs from the garage. Plus, they are easy to stack in closets, etc.

So, DO NOT waste a 2000cc oxygen absorber inside those kinds of bins that have handles incorporated into their lids. If you can find snap-on lids for bins that big, hey - give them a try. They aren't easy to find - or use - IMHO.

Be Certain: Use Feed Buckets with Lids!

So the best way to be absolutely sure of being AIRTIGHT is to use feed buckets with lids.

When using the feed-grade buckets, you absolutely can use the 2000cc oxygen absorbers inside them; they're perfect for this as the buckets really ARE airtight!
