Over time, I have come to rely on 400cc Oxygen Absorbers as my go to for all my Jars (up to 1/2 Gallon size) & Mylar Bags (up to 1 Gallon size). I got tired of all the Chart Recommendations & decided 400cc Oxygen Absorbers was the Key for me. This has worked out very well, as I only use one size 400cc Oxygen Absorber for all my Jars & Mylar Bags & I know when I use them, they take care of the Oxygen in all of them - Just go with 400cc or 500cc Oxygen Absorbers for everything you do & be done with it & eliminate the guessing & Headaches!!! Note: I do use a Chamber Vacuum Sealer & Oxygen Absorbers as much as possible & Oxygen Absorbers in my Mylar Bags with an Impulse Sealer when I have fragile Food I don't want to Crush!

Thank you so much for all you do for the freeze drying population. You are one of the very few that I trust on youtube.

I use my freeze fryer to vacuum seal my mason jars. Works great.

I have watched dozens of vlogs about oxygen absorbers, your presentation is by far the best... Pleasant & to the point!

Thank you for this series of videos. Doesnt matter if you have been freeze drying for years or a newbie, theres always something new to learn! Love your products too & yep this reminded me i need to place an order for bags & the parchment sheets I think I cant FD without! 😊.

well harrumph!! I chucked out a bunch of oxygen absorbers because they didnt shrink my mylar bags!!! lol Thankyou for that nugget of brilliance . I did not know that i needed to know all of this information . I just love the simple way you explained the whole de-oxygenating process. :) xxx

Thank you for this series. I’ve learned a tremendous amount of good info! Now if we just get everyone to watch your series and quit giving bad advice in your Facebook group! 🤦‍♀️🤷‍♀️

Answers to all my questions! THANKS!

I had a bunch of questions about O2 absorbers I've never seen answered...until now. Nice content!

We love our avid armor sealer. What a difference it made in our preservation.😊

Good info 👍. What I do with extra absorbers is store them in small used Mylar bags and vacuum seal them. 7mil works best. 5 mil will work but most of those have small holes in them after using them once.

I just love your videos...ALL of them. Have learned so much from you. THANKS! And I LOVE my freeze dryer!

It's weird no one caught this 10x14=1 gallon ≈ 750 cc oxygen 8x12=2 quarts ≈ 400cc 7x10=1 quart ≈ 200cc.... I guess it's worthwhile to fill up a bag with water to see what the bag capacity actually is, then (# of Ounces x 30 [to get cc's] x 0.2 [since oxygen is up to 20% of total volume] )

I've always just taken the O2 absorber I need out of the little clear bag then hit it with the impulse sealer to contain the rest. As long as you don't get wrinkles it works fine for me. I've only have one batch not seal and it had a very obvious wrinkle that I never noticed. Putting two or three in an empty jar seems like it would use up more than a flat bag that you can seal right up next to the absorber so it is basically just an individual wrapped packet. Oh yea turn you impulse sealer down to barely on, set to mylar it will just chop of the end of the plastic bag.....which sucks

Great video. I received that a id armour vacuum sealer for mother's day and it is my most used appliance. Love it. Thanks for the tips. 👍

I have had good luck sealing leftover OAs in a second bag using either my Avid Armor USV32 or my Food Saver. I often keep the Food Saver out next to the Avid Armor just for that purpose. I can do the OAs right away while sealing the food bags.

Excellent thanks

Thank you so much for this video. I am frustrated by the manufacturers of the oxygen absorbers not labeling the packets. I opened a box today of some I bought several months ago and can't tell what is what. There is printing all over the front and back sides, so why don't they include useful info like how many CCs they are?

You are amazing. Ty for the education you are giving me.

I have used hand warmers inside a plastic sandwich bag as an O2 absorber in my bucket sized bags.

This video is very informative, thank you. I just have a Foodsaver and I add o2 absorbers for dry goods. Someday I hope to buy a freeze dryer. I'd love to experiment with different dishes like you.

Thanks mate! Just did my first batch and was wondering what to do with leftover absorbers. Sealed them then put in a jar. Had no clue on size or how long they last. Really informative vid. Cheers!

Thank you for all your hard work researching this for us.

I would assume you vacuum out the oxygen from the container before sealing. You could put nitrogen in the bag or jar. It’s heavier than air and safe for food. They used to sell a small container for wine drinkers . Open you oxygen absorbers and place in a jar of nitrogen.

Thank you so much I'm new at this and I was worried about what to do with the extras. I ended up using some and now I realize they were done... So I will be using those packages of food ASAP. A learning process Thank you for the helpful information I've watched several of your videos.

Thank you so much for the information, this was the missing piece to my understanding of the freeze drying process. My Harvest Right runs almost non-stop and I’m always unsure about the correct absorber to use. I currently store in both jars and bags depending on how soon I intend on using the item.

This is not about absorbers but the tray lids. I absolutely love them and could not do without them! When budget allows I plan to buy another set.

Great vid with great info! Ordered the chamber sealer with your code. Thank you again!

I have purchases oxygen absorbers with the little dots and they have never changed color. After I used up the packet I set the indicator out on the counter just to see and they have been on the counter for a month and are still nice and pink. Other purchases have their indicators change fairly quickly. Good to have other ways to make sure they are still OK.

I have a chamber vac also. So I reseal the bag of oxygen absorbers in there bag using that. Little extra tid bit. If wanting to use the jar method, you can use the freeze drier to seal the jar

Thank you

Wow now I need to check mine . I will probably have to order all new ones. Thanks for sharing 👍 😊

Thank you for those precisions

Thanks for such great information 👍

Yer a Legend as us Brits say mate.Just about to commit to a small pro ordered direct from here in Edmonton Canada based on yer latest review of the pro

I'm so happy I found you! I'm planning on getting a freeze dryer and doing my research first

Good morning! We shared this amazing video to our Community tab. Thanks for another great video helping us answer any questions we have about oxygen absorbers!

Excellent video! Thanks!

Thank you for this video! I found this very informative. This video is a huge help! Have a blessed day! Wendy❤️🐞

Thank you, new to this! Very helpful 👍🏼

Very informative. Thank you.

If you squeeze a bunch of air out before sealing the bag, removing 20% of the remaining air will definitely give the bag a vacuum sealed look.

Do you have a video on how to use the armor vacuum sealer with jars? I’ve never tried it with them only with mylar bags. Thanks and love your videos they are so helpful

One thing to point out…Not ALL chamber sealers seal Mylar bags. I called my manufacturer to ask them about mine and they said they do not recommend Mylar bags in my chamber vac. Mine is an older one so maybe a mute point for all the newer chamber vacs. I have not done any research on it but next one I buy I will make sure it is capable of sealing Mylar.

I did not know about the pink n purple. (HR sent us a box just last month w machine) I notice what's left! Of what we haven't used or opened yet are purple! Idk how many we used that had the purple!

Thanks - great reminder!

Yep! This answered my questions! Thanks!

Wow! Just discovered your channel! Thank you for such thorough explanation on everything!! Definitely have been doing some things wrong but thankfully we’re only a month in, lol. Blessings to your family 🙏🏼

I use quart Mason jars about 25% of the time. When I use jars, I use a vacuum sealer function to seal the jars. Do I still need an oxygen absorber in those that are vacuum sealed?

Great info!

Thank you so much! God bless

Thank you, this helped a lot

Finally an answer to my question. My oxygen absorbers are hard with packages unopened. Guess they are no good 😟 .

I greatly appreciate your content! I always learn. I have a question: do you every use the 'vacuum' setting on the Harvest Right to vac seal jars?

Great info , I was just looking for this!!!

I use my regular vac sealer to reseal OX abs. If the pack is not the right kind of bag I make a new bag and drop the entire other bag in!

GREAT INFO!

Ty ty ty I needed that. ❤

Thank you for this video.

Great vid

The mixture inside an oxygen absorber is an iron alloy powder, a little salt, graphite and water. They are basically the same guts as hothands handwarmer packets. A combination oxygen and moisture absorber has aluminum iron alloy graphite and calcium chloride as the salt.

Question, what if you're sealing grain, same type and amounts in multiple mylar bags. Then say after using the same pack of oxygen absorbers and same size bag etc some of the bags vacuum pack tightly but others are still loose, and no noticeable damage to the bag or seal. Do the loosely packed bags need to be redone? That's what confuses me the most.

If you have a vacuum seal do you have to use an OA?

I’ve heard that there are certain food products (ex. Brown Rice) that you should not use oxygen absorbers with due to the potential risk of the creation of botulism. With that said … is there a list of foods that are safe to use by adding oxygen absorbers to ?

And now a few words, please, on how long to set the chamber sealer to run. Yes, I know the figures in the user manual, but some experienced knowledge for different situations would be helpful. Also, I used to store unused absorbers in small mylar bags, but found that a small Mason jar is indeed MUCH handier! After all, the chamber sealer is already running.

so There are expiration dates on the oxygen absorbers. When they come from the manufacturer, are those absolute??

How long after you seal the extra OAs up should it take for the indicator to turn back to pink color. Mine have been taking a day or two.

question. can i open up my past freezedried bags and insert an additional absorber, and seal it back up for storage? foods that i have dried in the last year?

Question…😊 Do you still need to use an oxygen absorber when using a chamber sealer?

Hey Brian what company does the graphics on your Mylar bag? Looking to do a custom bag for freeze dried candy logo!

I’m struggling to vacuum seal a 5 gallon Mylar bag. Can you do a video on a solution for that ?

Thank you for this video! Should I be using OAs in my vacuum sealed jars?

The only issue I see is that vacuum sealing foods in mylar bags that have a sharp edge, such as noodles. The sharp edges or corners will poke a hole in a mylar bag (or FoodSaver bag) and fail. I've even had beans in a bag that failed. I only use the vacuum sealer for meats I intend to deep freeze, and a few dry goods. Are you sure that FD foods have 0% moisture? I was taught that it can be 1-4% moisture.

I once contacted Avid they said I didn't an oxygen absorbers with their machine. I use one anyway, but thought that was interesting. I use absorbers with my food Saver attachment, are th ey necessary? Could you do another video using the Harvest Right to vacuum seal, and show us how you use the Avid with Mason jars?

With the vacuum chamber, does the food end up crushed so when opened you end up with food powder?

What are the pros/cons of using your freeze dryer for vacuum n sealing?

So, Hot Hands packets are oxygen absorbers?

Thanks for great content! I recently opened my freeze dried food from 4 years ago that was kept in an air tight jar but didn’t add oxygen absorber obviously because I didn’t know about this concept here. Now that I try to reconstitute it (freeze dried eggs to be specific) the consistency is not that great, taste is off and cooks bad. Are all the parameters affected when the FD food is packed without adequate oxygen elimination?

If your vacuum sealing do you need to use an oxygen absorber?

Unfortunately, your video was only now seen - wishing it was seen a year ago. Last week, I checked on several packages of absorbers that were left in the original packaging and, found every one is rock hard. I contacted the company and received no response. Apparently, that company is too busy to communicate with their patrons. Thank you for your informed videos.

CAN I USE IT WITH BREAD?

I just started using a stayfresh freezedryer; do you know the specs on the kind of pump oil it uses?

Does an absorber turn dark immediately then return to pink when returned to a vacuumed sealed environment

Why not offer individually wrapped OA’s ?

Do you have to use oxygen absorber on your avid armor chamber vacuum?

Can anyone tell me the proper temperature for freeze drying medicinal herbs?

Can h2o absorbers be recharged/reused?

Is silica same as oxigen absorber?

I am using an Avid Armor 300 but haven’t been using an oxygen absorber. Is that a problem?

Everyone has different sayings when it comes to oxygenators. Please can everyone get together and tell the same story.

If I used bad oxygen absorbers- can I open the bag, add different absorbers and reseal? Within what time period?

I came looking to see if I was supposed to open the oxygen absorber or not. 😅

Do you have any thoughts on why some OAP's (oxygen absorber packets for those who don't know the acronym) taken out of a new bag (with the freshness dot still pink) and laid out on the kitchen countertop would NOT get hard? Granted, we do live where the humidity is very low, but out of 3 OAP brands tested (Harvest Right, PackFresh, and the LDS store) the first two are still soft and pliable 20 days later, but the LDS packet was hard within (at most) two days. To me, this says the first two were failures, but maybe I'm missing something here? I felt them a couple of times a day and never felt any of the 3 getting warm. Thoughts are appreciated!

I just use the Avid Armor to seal the O2 absorbers in their original packaging.

Long term storage of oxegen absorbers? I thought they had a 1-2 year shelf life even when stored perfectly? I have a bunch and I am afraid to use them. I have used a inverted graduated beaker in water and tested them to determine if they are good but get questionable results. What say ye?

Iron oxide? So can't I just make my own? Have you tried the DIY oxygen absorbers?

So most of my early stuff with only 100 or 200 CC should be considered no good?

Asking for help.ordered my fd a little over 3 weeks ago. Set it up ,ran the test. Tried drying bread, cancelled after 40 hours, wasn't dry just frozen. Did all the vacuum test, everything was fine. Tried drying sliced tomatoes, machine doesn't go past 3/4 way dried, finally cancelled drying after 53 hours, not dried. HR suggested download New software and install. Done it, still doesn't work and I feel ignored by HR, no replies except download and reinstall. Anyone else having these problems

What does he mean a #10 can?

What’s wrong with silica gel? Does anyone think they’re ok for smaller retail packaging?
