This was a really interesting video. Your testing was easy to follow too. I hope Harvest Right see your video because it speaks to their commitment to quality for their customers. All the best from the UK 🇬🇧
Thanks for your excellent scientific analysis of the Harvest Right bags and oxygen absorbers. It was fascinating and inspired confidence when I package my freeze dried products.
Excellent video sir. Boy I wish more people made these kinds of videos. Nothing wrong with keeping companies honest. And well done harvest right. Hard to find a company these days that’s honest.
That was amazing. I always wondered if 02 absorbers were just as advertised so I did the overkill thing and used 500cc just in case. I guess I have trust issues! Thanks for sacrificing your time, expertise, the bag and 02 absorber for the cause. Much appreciated.
I did that also I used to as overkill in each gallon bag ; the thing is the bag did not shrink or look like the air was removed at all, the bags still look inflated like pillows so I am now worried that the absorbers were ineffective. Even though i used two of the oxygen absorbers and they were brand new out of their package. So i kind of gave up on long term storage. lol
@@sunnysummer7309 Remember you can change an element, you can't make it disappear. Some of the oxygen will be replaced with Carbon Monoxide. That's a good thing.
@@sunnysummer7309 An easy way for peace of mind is to vaccum seal your bag. That said, I think there is a very large safety margin as far as how freeze dried food will keep even if you only heat seal the bag and nothing else.
Thank you for all of your videos. It really helps when someone explains the how and why and doesn't just provide an answer with no real reasoning behind it.
This is great and makes me feel better since I don't know what to look for! I'd love to see you do an analysis on the Wallaby bags. I bought them and have enjoyed the thickness and what seems to me as a great quality bag, but wonder about the OA's since they seem smaller than the Harvest Right ones.

Subscribed! Very good videos on mylar bags and O2 absorbers! I appreciate the technical approach to your tests. I am returning recent purchase of mylar bags from Amazon sellers. They advertise the bags as 9 mil but that is a double layer measurement. Their O2 absorbers are also very sketchy.
Great video mate, Harvest Right is a company that I had planned to purchase from once I get a block of land and this shows that the company is well worth doing business with!
I feel like this title is not fair to Harvest Right. If you didn't watch the video you would assume there was an issue with a HR prodcut, where there is not. The research involved in this video is impressive, and I wish the title was more representative...and fair.
I thought that too in the beginning. I did let HR preview the video before release. They liked the clip and approved. I kept the title to peak peoples' interest. Thank you for the comment.
There is a problem with Harvest Right. We bought one, we have had to work on it and nurse it along to keep it running. Now the touch pad that you use to turn it on and off and select functions, doesn’t work. We have had it two months. I truly can not recommend this product and I know unfortunately they are one of the only companies out there, but if they would tell you up front that you have to be a mechanic and an electrician to keep it running, at least that would be the truth.
@@markforee7693mine lasted a year before the first self induced oops. HR was on it, told them it was my fault. They sent me a replacement part free of charge that was built wrong and fried my machine. Worked with them 2 months and got my machine running again at no cost to me. It was kinda long but I have no complaints against HR customer support. Contact them. Also I feel your pain at 2 years, it seems my machine doesnt work as quick as it use to. Idk if it is software or what. Watching mine, but I still recomend HR customer service. Best of luck to you!
Thanks for doing this it makes it easy to understand. I would love a freeze dryer, but I'm in NZ. The shipping is expensive, and when I talk to someone with an import licence about the harvest right freeze dryer, they look at me like I've got 2 noses on my face. !! A company in Auckland I believe has started to import them, but there's a huge wait and expense just yet.
That is just priceless 👌 I am looking for bags & oxygen absorbers on Amazon. Just had to send back shxwell brand for pin holes everywhere so don't even know if absorbers worked. Before that lost all my prep to wallaby from absorbers and holes I found afterwards. I never seen a testing gadget like you have 😮 I knew about calipers to measure skinny things or a feeler gauge in tiny spaces but that thing is awesome!! Any way I want to find that exact package of harvest right ✅ thanks so much.
Hi! Glad to be here. So informative. Could you do a comprehensive episode on botulism? Regarding canning etc. I would love it and I bet others would too. Maybe you have one could you refer me to it. Thank you for all you do!
Phil, this is an amazing video, but it went over my head. I am sorry I had to fast forward. The detail is amazing. Thank you for the hard work and for helping us out.
Over my head in some areas, but totally was able to follow. Very interesting. Best thing, it made me take time to devote to thinking about this. Subscribing and watching more videos.
I just asked fellow subscribers this evening for recommendations for the best mylar bags and absorbers. I never see anything showing material thickness and wanted to be able to compare.
Great testing video. I just ordered Wallaby Mylar bags, but ordered the Harvest Right O2 absorbers. They did take quite awhile to arrive, it seems worth the wait now based on your testing! 😃
Hi is there a reason you did not use the wallaby oxygen absorbers? reason i ask you is because the wallaby bags i used their oxygen absorbers but my bags still look inflated as though the absorbers didn't work?
I got a Harvest Right FD two weeks ago and it came with 50 count of 700 cc oxygen absorbers. They did not feel warm at all to the touch when I opened a package of 10. So I put 10 in a quart size jar and it cannot seal the lid. I have some very old oxygen absorbers that were barely warm to the touch. I then put in them in a quart jar and they sealed the jar. So now I need to order oxygen absorbers, but not from Harvest Right.
Last night I took some Oa's out of my small jar and put into the product I was FDing. I always take the jar with the OA packets and seal it in my chamber sealer to keep the packets nice and fresh. Last night I forgot to do that. The lid was on tight, but this morning it was NOT sealed even though it had about 10 packets in it. I assumed those OA's were no good so I tossed them in the garbage. I'm bummed because I now wonder if I just wasted a bunch of food. I am fortunate enough to have use of a #10 can sealer and #10 cans. What do you think? Have I just ruined some food? Should I open those cans and use new ones on the last 6 can's of food? I really don't know if any of the OA's I used from that bunch are any good.
interesting testing methods. I should point out that air will readily dissolve (and diffuse) into water. it is likely that your results for oxygen volume is off because of this. The one package was probably somewhat better than your test would indicate.
I was thinking a light, nonvolatile oil could be used in place of water. I will retest in a year or so. Since I started with water, to be consistent and fair, I needed to use the same test method.
Thanks to the United Nations the old MSDS is now just a SDS. It has been reformatted to be international under Global Harmonization System. It was adopted by the US on March 26, 2012.
So happy to find your channel! I'm looking into canning, pickling, and fermenting supplies videos but freeze drying in now on my list of ways to keep the food I grow much longer. So much of it has to go into the compost bc I have nothing to preserve my harvests. I am still new to gardening so I had to get the basics for that down well enough to move on to the next level and I feel like I'm finally ready this year!
@@Philat4800feet actually I became very depressed after my first child and I can finally say that I am the happiest I have ever been after starting this garden so I think you are 100% right!
New to your channel and I really appreciate your time and I found it (for me and my taste as an average housewife and very sad to say that I can't afford a freeze dryer but pray that I will get 1 for our large family with 5 children) this was weirdly interesting and captivating for me to watch! I now have to go and watch more of your videos!!
Excellent video, thank you for your hard work making this. It's funny, because just today I was loading some bags and thinking to myself, "I wonder if these o2 absorbers are any good?". Now I know and feel good about it.
You know, you do the best commercials around. I use many of your products and don’t take this the wrong way, but you would be a great comedic actor. Your writers and directors are great also.🤗
I’ve been using Wallaby brand Mylar and oxygen absorbers……I’m having doubts if the oxygen absorbers are any good…….very few packets seem to working correctly……..very few of my preps (Mylar bags) have tightened up, as in bricks…… Fascinating topic…..thank you
Great video. thanks! You may want to consider using more than one 'significant figure'... for example, 1g on your scale could be as low as 0.5g and as high as 1.49g (and the scale could be rounding the measurement to 1g and you wouldn't know it), and so ideally you should be using a scale that has a minimum increments of 0.1g or even 0.01g for the amounts you are using.
A quart jar holds 946 cc. The air we breathe contains 21% oxygen. (946 cc x .21 = 199 cc). A standard oxygen absorber is rated to "absorb" (oxidize) 300 cc of oxygen. Many OA will absorb two to three times this amount. After 1-2 hours the oxygen in my jar will be gone, absorbed. The surrounding fluid around the jar will be sucked up into the jar to fill the oxygen void. The water stops at the 199 cc level, the amount of available oxygen. The thermochemical process stops because there isn't any more oxygen. This is when I exchange the air to allow the process to continue until the absorber can't absorb anymore oxygen. The total amount of "sucked up" colored water is added up for the total capacity.
I don't need my o2 absorbers to come in a box. An expensive box no less, gloss coloring, die cut box with window. I don't need a design on Mylar bags either (of food in a jar). All adds to the cost. I suspect they are more for advertising when you get them with a new machine. Thank you for doing these videos.
@@marycanfield1974 Harvest Right does offer a bag that has the bottoms that allow them to stand on their own. They are also resealable - with a plastic zip-type seal. (One also uses the sealer to seal the top of the bag above the zip.) They are a smaller size; without looking and measuring I'm estimating they are approx 6" x 9or10". Very handy. For my circumstance with storing small portions they are terrific.
@Phil at 4800 feet I have been using your method of shaking down product then fold over mylar bag at the lowest point and stacking them until you can do many OAs at one time. Its been working great. I had been doing that however realized later that I ran out of OAs. Can any or all of these items still be used by adding the OA at this later date? : 6/30 dried berries 7/15 Sourcream 7/22 cottage cheese Thanks
I have run out of bags and absorbers too. I'll place my food in zip lock bags for a couple of weeks without problems. or you can vacuum pack the food: ua-cam.com/video/WjIa1WUmnzw/v-deo.html
Very interesting....can you please do the wallaby product of mylar bags? I used them and i don't see not one shrinkage of the packaging after i put in the oxygen absorbers...I don't think they work!
I recently puchased the large freeze dryer from Harvest Right. I used their 300cc oxygen absorbers and 7mil mylar bags. The absorbers didn't work at all. After 24 hours, I cut the bags open and placed two 300cc absorbers in each bag. 24 hours later, no change. Each of the bags were double sealed with the impulse sealer set to 7. I cut the bags open again and used an off brand, 300cc absorber. Within 24 hours, there was an obvious vacuum on each of the bags.
Oxygen absorbers work by "burning up" or oxidizing the oxygen in the air. This is done with powdered iron. The rate of oxidation is controlled by salt and carbon. Some OAs take up to 4-5 days to work. Some 12-24 hours. Not all OAs will pull a vacuum on a bag. If you're interested in vacuum sealing, your FD can perform this task. One cup is 237 cc. This will give you an idea of how much O2 will be absorbed out of 1129 cc (nearly 5 cups). However, as it "absorbs" oxygen, the absorbers produce other gases, primarily carbon monoxide.
Perhaps someone can answer something that HR cannot/will not answer. I took a fresh 700cc OAP out of the package before I sealed the rest up in a jar and vacuum packed it - then put the date on it, and laid it on the kitchen counter. The pack was soft and flour like, and after 10 days on the counter, it still is exactly like it was the day I started the "test". Why has it not gotten hard? Everything I read says that when they have absorbed the oxygen to it's max ability, it will be hard or at least really crunchy. Please help me figure this out? HR dingbat that I got on the phone was completely stuck on the little pink paper dot as the accurate way to tell that the OAP is good - hogwash - it's a piece of paper! Please show me where I am wrong?
Here are my thoughts on your test: the hard and crunchy OA happens in a small confined space. While the OA oxidizes the oxygen it creates its own unique atmosphere. The OA will generate Carbon Monoxide, a small amount of moisture, and a few other gases from the thermochemical reaction. Your "open air" test doesn't confine the byproducts and are vented into the air and perhaps, allows the OA to "dry out" and remain in a more powdery state.
@@Philat4800feet Interesting thoughts on the "test". I guess the LDS OA's have a different formulation then - because in very little time on the counter, those got rock hard. I'm not sure how to test the HR packs (at 700cc) in the appropriate sized container to make it get crunchy though. How did your packet feel after your water test - hard or still soft?
@@Philat4800feet So if each manufacturer is different with the ingredients of the OA's, and some get hard pretty fast sitting on the counter (as I would have assumed they all would based on their dire warnings of leaving them out too long when you're working with them) - then how would a person know the absolute best way to test for a good working OAP? Obviously, based on the comments here, the water test isn't the "end all" test either. I'm so fed up that I'm about ready to chuck all mylar and OAP's and just use jars and my food saver!
I have never seen a OA work that fast. The majority takes hours. All OA use powdered iron to "absorb" oxygen. They use other chemicals, charcoal and salts, to control and improve the rates of absorption. ua-cam.com/video/lTLWNVQvMsk/v-deo.html
don't have a harvest right freeze dryer (way to expensive imo) but the shipping issue is not technically a issue due to the fact that there are supply chain issues, especially with items coming from china. Need to get some mylar bags and o2 packets for when I dehydrate stuff (veggies for soups and hotdishes). Will be looing into the harvest right brand now for those.
I don’t know if Harvest Right sells any bags better than the ones that were included with my Harvest Right machine, but I don’t like them. They’re not ziplock, heat seal only, and they’re fully transparent on one side, leaving whatever is in them exposed and susceptible to light degradation, unless stored in lightproof containers.
@@Philat4800feet I just got my machine three weeks ago, to came with 50 bags that are printed on one side and transparent on the other side, with just a straight, open top, with no ziplock.
Thank you so much Phil. Could you tell me if I can use Silica Gel Packs? I ordered some from Amazon, but they came packed with air in the bag which concerned me. However, they’re orange which signifies they are fresh, they turn green when they have absorbed moisture. You can dry them out in the microwave, supposedly. Is there any reason why these won’t work? I picked them because they’re reusable. Thank you so much for listening.
@@Philat4800feet Awe, disappointed, I so wish you had, as I have them sitting here and I’m not sure what to do. They say they are food safe. You are so good at examining these sorts of things. If they hadn’t arrived with air in the bag I wouldn’t have questioned them, but they are still the fresh color. It’s so confusing. Thank you for responding.
The issue with 21% O2 is correct, however, if you bag your food while still hot/warm the food can heat the air in the bag. Warm air expands. When the air cools, the air will retract and suck the bag in even more. Before my vacuum chamber, I would heat the bags up in the oven at 140 degrees and then seal the hot bags.
Hello! Mr. Phil thank you for all the work and research you do in the area of Myler bags and oxygen absorbers. I have a question it seems nobody can answer me, it has to do with way we should not put oxygen absorbers in salt nor sugar. the common answer is that the salt and sugar will get hard as a rock, but nobody can explain way. Mr. Phil do you have an Idea way this happens(salt and sugar get hard as a rock if you store with oxygen absorbers) if it does happen. Thank You Mr. Phil
I have not heard of that. Perhaps the oxygen absorbers are being found guilty of a crime they didn't commit. When an oxygen absorber is removed from its protective packaging, the moisture in the surrounding atmosphere begins to mingle with the iron particles inside of the Oxygen Absorber sachet. As the oxygen molecules from the moisture interact with the iron (Fe) particles, rust begins to develop and "burns" up the oxygen. Perhaps the real culprit is the humidity in the air at the time of sealing.
@@Philat4800feet Thank You! Mr. Phil for your feed back, salt and sugar being hygroscopic will make, like you said humidity the culprit. not the lack of oxygen. Well you actually inspire me to do a little experimenting of my own. I'll put some salt and sugar into mylar bags and drop some oxygen absorbers and see what happened. I'll let you know of results. Thank you for taking from your time to answer. Sincerely Michael
I just bought a freeze dryer and it was the first time using Mylar bags and oxygen absorbers. I don’t think the ones I got with the machine work that well. I do everything they tell you to do but some bags form around the food but most did not.
If you want the bag to form around the food you'll need to do two things: 1. Place warm food in the bag and seal it. As the food cools down it will form a low vacuum. 2. Vacuum seal the bag with your freeze drier. ua-cam.com/video/nHM2cnf_FY8/v-deo.html Try folding the top all the way over on the food. You need to get as much air out of the bag. While the bag is folded over raise the top up enough to seal.
@@Philat4800feet This is a good point. Also, the bags forming around the food doesn't mean the absorber worked or didn't work. Oxygen is about 19% of air and my understanding is that an oxygen absorber only removes oxygen (not the other gasses)
Hi Phil, hope you are fine. Can I also package the fruits in kind of „Pringles Cans“ and seal them with a sealing machine? I want a „harder“ package that protects the breakable veggies 🙏🏽
It appears someone set the standard that a one gallon bag requires a 300 cc oxygen absorber. If this is correct, a one quart bag would need a 75 cc absorber. With that said, a 100 cc absorber should work with a one quart bag. I would do my best to remove as much air out of the bag as possible or to fill a jar as full as possible to displace the air before sealing.
Is there any chance you could do a inspection of the oxygen packs that are purchased from uline 300cc ? I started using them in place of harvest right because because some of my harvest right oxygen packs Jim packs got left out overnight and they were still very pliable whereas the ones from utiline turned rock hard so I assumed that harvest rights weren't really that well and started using these from euline could you please investigate
I've had lots of requests. I'll see what I can do. U-Line is just the distributor. Clarient Corp located in North Carolina makes them under the name Oxy-Guard.
Thank you Phil, we just ordered ours May 5th a few days ago. I have a question on if you know if anyone has cleaned their freeze dryer with a steamer; dupray steamer is what I have. ? It ivaporates then taking a papertowel to insure a dry barrel.! Thank you so much phil.
it should still be a water vapor proof bag. it could be using a different type of barrier material to provide the water vapor proof protection. check out it's water vapor transmission rate and compare that with the water vapor transmission rate of the DuPont mylar bag.
We bought oxygen absorbers and apparently they were a bad batch. I was putting up dry beans in canning jars. After 3 trys on each jar, I finally just bought a jar attachment for my food saver
@@Philat4800feet 🤔 I may just do that... for fun. Sadly, I don't trust any of them now. Everything is getting too expensive to chance it. Especially if I have to go in and check the seals every other day. Is it safe to dispose of the packets in the garbage?
Don't forget with your water test you are basically making a barometer so atmospheric pressure will probably affect your results especially if was higher in the jar when you started and then it drops outside or vice versa.
you can make your own oxygen desiccant from a few common house hold items. rice or natural clay kitty litter also natural clay "oil spill" clean up "safe t zorb" its usually sold as. also called turface..
During the six day run the weather was pretty consistent. The high was 30.24 in/hg the low was 30.02 in/hg. However, this was coming from an official weather recording station, over a small mountain and 47 miles away. I feel confident in the test to say the absorber was true to the rating of 300 cc. although it did much better.
Good video but I would have liked for you to weigh the used oxygen absorber at the end of the experiment and possibly opened it to see if there was a difference in the weight of it's separate contents. I have heard that oxygen absorbers can be restored by drying them out in your oven at a very low temperature. The lowest my oven goes is 170 degrees F. My dehydrator can be set at 120 degrees F. Of course my next question would be, how efficient would the dried/reused oxygen absorbers be in comparison to the new ones. Lastly, would freeze drying my used oxygen absorbers give them new life? It doesn't seem sustainable or environmental to constantly be sending little plastic bags of iron, salt, carbon & sodium chloride to landfill. Thanks for your answer in advance. I am thinking you may have actually weighed the packet at the end of the experiment but just not included the info in your video.
Good idea. I still have many of those old oxygen absorbers. One (1) cc of oxygen weighs 0.001429 grams. Many of my tests were able to absorb 1000cc. So, 1000cc x 0.00149 = would equal 1.49 grams. My scale should be able to detect that amount. Some of the oxygen, instead of being absorbed, is converted to CO gas instead.
Since the air in the mylar bag is not pure oxygen, it is normal to not see a lot of shrink from the oxygen absorbers. Air is 78 percent nitrogen and only 21 percent oxygen. Oxygen absorbers only remove the oxygen, not the nitrogen and that is okay.
To keep the absorber out of the water. I don't think the tape would have moisture, but the environment, within the jar, would have an increased level of humidity.
I buy from pack fresh USA... They recently changes the look (maybe different supplier??) of their oxygen absorbers. They used to sell genuine Dupont Mylar bags that were awesome. Now they sell a different brand that seem good too. Maybe check them out for testing... TY
Trick question. I'm trying to find a test to determine if it's really Mylar or Polyester film. These two items are not the same. I like FreshpakUSA Made in the USA and they add extra powdered iron.
How can you tell your Mylar bags are polyester film and not a genuine Mylar bag? I've ordered Mylar bags from Amazon and it's 14 ml thick and made in China. I am wondering whether this is genuine Mylar bag.
DuPont sells very little Mylar to China. In their words "if it's coming from China, it's probable not Mylar" real 2.0 mil Mylar out performs 7.0 mil bags. See this video: ua-cam.com/video/tKdjv-ly03Y/v-deo.html
@@Philat4800feet The one I bought is very thick and stiff since it claim to be 14 ml. Which bag do you recommend? Do you recommend Harvest Right bag as the best option?

Also I feel your pain at 2 years, it seems my machine doesnt work as quick as it use to. Idk if it is software or what. Watching mine, but I still recomend HR customer service. Best of luck to you!
I agree!!
Thanks for doing this it makes it easy to understand. I would love a freeze dryer, but I'm in NZ. The shipping is expensive, and when I talk to someone with an import licence about the harvest right freeze dryer, they look at me like I've got 2 noses on my face. !!
A company in Auckland I believe has started to import them, but there's a huge wait and expense just yet.
Best of luck to you
Wow! Someone gets an A+ for doing their homework!! Love it! Thanks for the info
I hate to admit I was a B/C student in school.
That is just priceless 👌 I am looking for bags & oxygen absorbers on Amazon. Just had to send back shxwell brand for pin holes everywhere so don't even know if absorbers worked. Before that lost all my prep to wallaby from absorbers and holes I found afterwards. I never seen a testing gadget like you have 😮 I knew about calipers to measure skinny things or a feeler gauge in tiny spaces but that thing is awesome!! Any way I want to find that exact package of harvest right ✅ thanks so much.

Phil, this is an amazing video, but it went over my head. I am sorry I had to fast forward. The detail is amazing. Thank you for the hard work and for helping us out.
Glad it was helpful!
Over my head in some areas, but totally was able to follow. Very interesting. Best thing, it made me take time to devote to thinking about this. Subscribing and watching more videos.
Glad it was helpful!
I just asked fellow subscribers this evening for recommendations for the best mylar bags and absorbers. I never see anything showing material thickness and wanted to be able to compare.
Great testing video. I just ordered Wallaby Mylar bags, but ordered the Harvest Right O2 absorbers. They did take quite awhile to arrive, it seems worth the wait now based on your testing! 😃
aren't wallaby o2 absorbers packed single for each bag?
Wallaby O2 absorbers are packed in counts of 10.
Hi is there a reason you did not use the wallaby oxygen absorbers? reason i ask you is because the wallaby bags i used their oxygen absorbers but my bags still look inflated as though the absorbers didn't work?
I purchased the Harvest O2 absorbers before I ordered the Wallaby bags. I am using the Wallaby O2 absorbers as well. Both work great
@@sunnysummer7309 agree….I’m having the same issues with Wallaby’s products.
I got a Harvest Right FD two weeks ago and it came with 50 count of 700 cc oxygen absorbers. They did not feel warm at all to the touch when I opened a package of 10. So I put 10 in a quart size jar and it cannot seal the lid. I have some very old oxygen absorbers that were barely warm to the touch. I then put in them in a quart jar and they sealed the jar. So now I need to order oxygen absorbers, but not from Harvest Right.
OAs should feel like flour. If they feel like sand or gravel, most likely they're bad. Try Discount Mylar or Distribution services.
@@Philat4800feet I will check them out. Thank you.
Well done, Phill. Enjoyed and appreciate your experiment. First time on your channel. Will view your other video's.
Welcome aboard!
Last night I took some Oa's out of my small jar and put into the product I was FDing. I always take the jar with the OA packets and seal it in my chamber sealer to keep the packets nice and fresh. Last night I forgot to do that. The lid was on tight, but this morning it was NOT sealed even though it had about 10 packets in it. I assumed those OA's were no good so I tossed them in the garbage. I'm bummed because I now wonder if I just wasted a bunch of food. I am fortunate enough to have use of a #10 can sealer and #10 cans. What do you think? Have I just ruined some food? Should I open those cans and use new ones on the last 6 can's of food? I really don't know if any of the OA's I used from that bunch are any good.
How valuable is the food in the cans? Rather than recan the food, you could use the food sooner than later.
Well done. Thank you for your time doing this. Grace to you and may God bless you.

WOW!! FIRST TIME WATCHING YOUR CHANNEL. THANK YOU FOR ALL THE INFORMATION.
Thanks for watching, Hope it's not too much
interesting testing methods. I should point out that air will readily dissolve (and diffuse) into water. it is likely that your results for oxygen volume is off because of this. The one package was probably somewhat better than your test would indicate.
I was thinking a light, nonvolatile oil could be used in place of water. I will retest in a year or so. Since I started with water, to be consistent and fair, I needed to use the same test method.
It is a MSDS. Material Safety Data Sheet. I use to work with it for trucks and in a large storeroom for a paper company.
Thanks to the United Nations the old MSDS is now just a SDS. It has been reformatted to be international under Global Harmonization System. It was adopted by the US on March 26, 2012.
So happy to find your channel! I'm looking into canning, pickling, and fermenting supplies videos but freeze drying in now on my list of ways to keep the food I grow much longer. So much of it has to go into the compost bc I have nothing to preserve my harvests.

Fascinating topic…..thank you
Do they feel like flour or sand inside?
Wow fantastic video! Thank you.
Phil thank you so much for your examination time, can you do an update on Uline company, I am curious
U-Line is a distributor. I'll try to find out who the manufacture is.
U-Line's 10 x12 bag is only 2.5 mil (part # S-21994) This is really thin. Is this the same product?
Great video. thanks! You may want to consider using more than one 'significant figure'... for example, 1g on your scale could be as low as 0.5g and as high as 1.49g (and the scale could be rounding the measurement to 1g and you wouldn't know it), and so ideally you should be using a scale that has a minimum increments of 0.1g or even 0.01g for the amounts you are using.
I agree, but like I tell my kids: "We're not working on the space shuttle". I guess I could find a finer scale.
I don’t understand how you measured total O2 absorption because you periodically emptied the jar. Did you measure it incrementally?
A quart jar holds 946 cc. The air we breathe contains 21% oxygen. (946 cc x .21 = 199 cc). A standard oxygen absorber is rated to "absorb" (oxidize) 300 cc of oxygen. Many OA will absorb two to three times this amount. After 1-2 hours the oxygen in my jar will be gone, absorbed. The surrounding fluid around the jar will be sucked up into the jar to fill the oxygen void. The water stops at the 199 cc level, the amount of available oxygen. The thermochemical process stops because there isn't any more oxygen. This is when I exchange the air to allow the process to continue until the absorber can't absorb anymore oxygen. The total amount of "sucked up" colored water is added up for the total capacity.
I have used their Food Saver and mylar bags. no complaints.
Nether do I. This series is to show other options
Hi Phil. Is it possible to reconstitute (de-oxygenize) the HarvestRight oxygen absorbers?
Sorry, no. It's a chemical reaction.
Great review!! Thank you for peace of mind!!
Excellent. Now I am wondering how to evaluate the best mylar bag sealer machine. So far I have a dehydrator.
Thank you.
The sealer from HR has worked well.
I don't need my o2 absorbers to come in a box. An expensive box no less, gloss coloring, die cut box with window. I don't need a design on Mylar bags either (of food in a jar). All adds to the cost. I suspect they are more for advertising when you get them with a new machine. Thank you for doing these videos.
Agreed. I would like to see some of the bags with the bottoms that make it possible for them to stand on their own
I agree.
@@marycanfield1974 Harvest Right does offer a bag that has the bottoms that allow them to stand on their own. They are also resealable - with a plastic zip-type seal. (One also uses the sealer to seal the top of the bag above the zip.) They are a smaller size; without looking and measuring I'm estimating they are approx 6" x 9or10". Very handy. For my circumstance with storing small portions they are terrific.
@@marycanfield1974 yes!! I definitely agree!
Very interesting video. However, I believe 4g iron powder times 300cc per 1 gram is 1200 cc not 1600cc

Thank you so much, big help. 👍
@Phil at 4800 feet I have been using your method of shaking down product then fold over mylar bag at the lowest point and stacking them until you can do many OAs at one time. Its been working great. I had been doing that however realized later that I ran out of OAs. Can any or all of these items still be used by adding the OA at this later date? : 6/30 dried berries 7/15 Sourcream 7/22 cottage cheese

Very interesting....can you please do the wallaby product of mylar bags? I used them and i don't see not one shrinkage of the packaging after i put in the oxygen absorbers...I don't think they work!
Lots of request for Wallaby
I recently puchased the large freeze dryer from Harvest Right. I used their 300cc oxygen absorbers and 7mil mylar bags. The absorbers didn't work at all. After 24 hours, I cut the bags open and placed two 300cc absorbers in each bag. 24 hours later, no change. Each of the bags were double sealed with the impulse sealer set to 7. I cut the bags open again and used an off brand, 300cc absorber. Within 24 hours, there was an obvious vacuum on each of the bags.
Oxygen absorbers work by "burning up" or oxidizing the oxygen in the air. This is done with powdered iron. The rate of oxidation is controlled by salt and carbon. Some OAs take up to 4-5 days to work. Some 12-24 hours. Not all OAs will pull a vacuum on a bag. If you're interested in vacuum sealing, your FD can perform this task. One cup is 237 cc. This will give you an idea of how much O2 will be absorbed out of 1129 cc (nearly 5 cups). However, as it "absorbs" oxygen, the absorbers produce other gases, primarily carbon monoxide.
Well done Phil as usual. Thank You.
More to come
Perhaps someone can answer something that HR cannot/will not answer. I took a fresh 700cc OAP out of the package before I sealed the rest up in a jar and vacuum packed it - then put the date on it, and laid it on the kitchen counter. The pack was soft and flour like, and after 10 days on the counter, it still is exactly like it was the day I started the "test". Why has it not gotten hard? Everything I read says that when they have absorbed the oxygen to it's max ability, it will be hard or at least really crunchy. Please help me figure this out? HR dingbat that I got on the phone was completely stuck on the little pink paper dot as the accurate way to tell that the OAP is good - hogwash - it's a piece of paper! Please show me where I am wrong?
Here are my thoughts on your test: the hard and crunchy OA happens in a small confined space. While the OA oxidizes the oxygen it creates its own unique atmosphere. The OA will generate Carbon Monoxide, a small amount of moisture, and a few other gases from the thermochemical reaction.
Your "open air" test doesn't confine the byproducts and are vented into the air and perhaps, allows the OA to "dry out" and remain in a more powdery state.
@@Philat4800feet Interesting thoughts on the "test". I guess the LDS OA's have a different formulation then - because in very little time on the counter, those got rock hard. I'm not sure how to test the HR packs (at 700cc) in the appropriate sized container to make it get crunchy though. How did your packet feel after your water test - hard or still soft?
After the tests, the OA are all hard. And the ingredients are different.
@@Philat4800feet So if each manufacturer is different with the ingredients of the OA's, and some get hard pretty fast sitting on the counter (as I would have assumed they all would based on their dire warnings of leaving them out too long when you're working with them) - then how would a person know the absolute best way to test for a good working OAP? Obviously, based on the comments here, the water test isn't the "end all" test either. I'm so fed up that I'm about ready to chuck all mylar and OAP's and just use jars and my food saver!
I have never seen a OA work that fast. The majority takes hours. All OA use powdered iron to "absorb" oxygen. They use other chemicals, charcoal and salts, to control and improve the rates of absorption.

don't have a harvest right freeze dryer (way to expensive imo) but the shipping issue is not technically a issue due to the fact that there are supply chain issues, especially with items coming from china. Need to get some mylar bags and o2 packets for when I dehydrate stuff (veggies for soups and hotdishes). Will be looing into the harvest right brand now for those.
I have one and recommend not buying one because they are pieces of shit.
I don’t know if Harvest Right sells any bags better than the ones that were included with my Harvest Right machine, but I don’t like them. They’re not ziplock, heat seal only, and they’re fully transparent on one side, leaving whatever is in them exposed and susceptible to light degradation, unless stored in lightproof containers.
How long ago? All the bags I've purchased are solid on both sides
@@Philat4800feet I just got my machine three weeks ago, to came with 50 bags that are printed on one side and transparent on the other side, with just a straight, open top, with no ziplock.
@@jdsbees3257 I would keep them in a dark place
My havest right was lost during shipping I got the accessories but they lost the freeze dryer that the accessory box was strappes to
"Lost" a giant appliance but not the small box it was strapped to? Hmmm
Hope it was insured.
Thank you so much Phil. Could you tell me if I can use Silica Gel Packs? I ordered some from Amazon, but they came packed with air in the bag which concerned me. However, they’re orange which signifies they are fresh, they turn green when they have absorbed moisture. You can dry them out in the microwave, supposedly. Is there any reason why these won’t work? I picked them because they’re reusable. Thank you so much for listening.
I have not test, nor have I used, silica gel packs. I'll need to look into them.
@@Philat4800feet Awe, disappointed, I so wish you had, as I have them sitting here and I’m not sure what to do. They say they are food safe. You are so good at examining these sorts of things. If they hadn’t arrived with air in the bag I wouldn’t have questioned them, but they are still the fresh color. It’s so confusing. Thank you for responding.
@@Sam-y5d3j I can understand the desire to use them. If food is freeze dried properly I can't see the reason for using them. Make sense?
The issue with 21% O2 is correct, however, if you bag your food while still hot/warm the food can heat the air in the bag. Warm air expands. When the air cools, the air will retract and suck the bag in even more. Before my vacuum chamber, I would heat the bags up in the oven at 140 degrees and then seal the hot bags.
@@Philat4800feet great, loved to hear your verdict!
I just found your channel. Wow this was great info!! I subscribed!
Welcome aboard!
Hello! Mr. Phil thank you for all the work and research you do in the area of Myler bags and oxygen absorbers. I have a question it seems nobody can answer me, it has to do with way we should not put oxygen absorbers in salt nor sugar. the common answer is that the salt and sugar will get hard as a rock, but nobody can explain way. Mr. Phil do you have an Idea way this happens(salt and sugar get hard as a rock if you store with oxygen absorbers) if it does happen. Thank You Mr. Phil
I have not heard of that. Perhaps the oxygen absorbers are being found guilty of a crime they didn't commit.
When an oxygen absorber is removed from its protective packaging, the moisture in the surrounding atmosphere begins to mingle with the iron particles inside of the Oxygen Absorber sachet. As the oxygen molecules from the moisture interact with the iron (Fe) particles, rust begins to develop and "burns" up the oxygen. Perhaps the real culprit is the humidity in the air at the time of sealing.
@@Philat4800feet Thank You! Mr. Phil for your feed back, salt and sugar being hygroscopic will make, like you said humidity the culprit. not the lack of oxygen. Well you actually inspire me to do a little experimenting of my own. I'll put some salt and sugar into mylar bags and drop some oxygen absorbers and see what happened. I'll let you know of results. Thank you for taking from your time to answer. Sincerely Michael
They are not freeze dried. You need to put moisture absorbers in those. Your welcomed!
How can I tell if a bag is made by Dupont is there a mark on the bag I should be looking for?
Not sure. Doing research on that.
I just bought a freeze dryer and it was the first time using Mylar bags and oxygen absorbers. I don’t think the ones I got with the machine work that well. I do everything they tell you to do but some bags form around the food but most did not.
If you want the bag to form around the food you'll need to do two things:
1. Place warm food in the bag and seal it. As the food cools down it will form a low vacuum.
2. Vacuum seal the bag with your freeze drier.
ua-cam.com/video/nHM2cnf_FY8/v-deo.html
Try folding the top all the way over on the food. You need to get as much air out of the bag. While the bag is folded over raise the top up enough to seal.
@@Philat4800feet This is a good point. Also, the bags forming around the food doesn't mean the absorber worked or didn't work. Oxygen is about 19% of air and my understanding is that an oxygen absorber only removes oxygen (not the other gasses)
@@carolclarkson4859 correct. Absorbers remove the oxygen, and to some extent, replace it with carbon monoxide.
Hi Phil, hope you are fine. Can I also package the fruits in kind of „Pringles Cans“ and seal them with a sealing machine? I want a „harder“ package that protects the breakable veggies 🙏🏽
Canning jars can be used in place of bags. Jars are reusable and see through. There are pros and cons with bags and jars
So for quart mylar bags would 100 cc oxygen absorbers be sufficient for one year storage?
It appears someone set the standard that a one gallon bag requires a 300 cc oxygen absorber. If this is correct, a one quart bag would need a 75 cc absorber. With that said, a 100 cc absorber should work with a one quart bag. I would do my best to remove as much air out of the bag as possible or to fill a jar as full as possible to displace the air before sealing.
Is there any chance you could do a inspection of the oxygen packs that are purchased from uline 300cc ? I started using them in place of harvest right because because some of my harvest right oxygen packs Jim packs got left out overnight and they were still very pliable whereas the ones from utiline turned rock hard so I assumed that harvest rights weren't really that well and started using these from euline could you please investigate
I've had lots of requests. I'll see what I can do. U-Line is just the distributor. Clarient Corp located in North Carolina makes them under the name Oxy-Guard.
Fantastic video. THANK YOU, PHIL!
Many thanks!
Thank you Phil, we just ordered ours May 5th a few days ago.

@@ashyslashy5818 Would your share your problems with me? I'd love to see you be a happy freeze drier.
it should still be a water vapor proof bag. it could be using a different type of barrier material to provide the water vapor proof protection. check out it's water vapor transmission rate and compare that with the water vapor transmission rate of the DuPont mylar bag.
We bought oxygen absorbers and apparently they were a bad batch. I was putting up dry beans in canning jars. After 3 trys on each jar, I finally just bought a jar attachment for my food saver
Did the contents of the oxygen absorbers feel like flour or sand/gravel? This is one way to tell if they're good or not.
@@Philat4800feet sandy. I just decided not to chance it and pulled them all😉. I still have them because I wasn't sure how to dispose of them
@@JB-le6zm Maybe you should do your own water test on one.
@@Philat4800feet 🤔 I may just do that... for fun. Sadly, I don't trust any of them now. Everything is getting too expensive to chance it. Especially if I have to go in and check the seals every other day. Is it safe to dispose of the packets in the garbage?
Don't forget with your water test you are basically making a barometer so atmospheric pressure will probably affect your results especially if was higher in the jar when you started and then it drops outside or vice versa.
Yup, I can get some readings without anything in the jar. That would be a good side by side comparison for the next test.
you can make your own oxygen desiccant from a few common house hold items. rice or natural clay kitty litter also natural clay "oil spill" clean up "safe t zorb" its usually sold as. also called turface..
You're referring to a dessicant (which removes water), while an oxygen absorber removes oxygen.
Just wondering, did you check the Barometric Pressure while doing the water test?
During the six day run the weather was pretty consistent. The high was 30.24 in/hg the low was 30.02 in/hg. However, this was coming from an official weather recording station, over a small mountain and 47 miles away. I feel confident in the test to say the absorber was true to the rating of 300 cc. although it did much better.
Good video but I would have liked for you to weigh the used oxygen absorber at the end of the experiment and possibly opened it to see if there was a difference in the weight of it's separate contents. I have heard that oxygen absorbers can be restored by drying them out in your oven at a very low temperature. The lowest my oven goes is 170 degrees F. My dehydrator can be set at 120 degrees F. Of course my next question would be, how efficient would the dried/reused oxygen absorbers be in comparison to the new ones. Lastly, would freeze drying my used oxygen absorbers give them new life? It doesn't seem sustainable or environmental to constantly be sending little plastic bags of iron, salt, carbon & sodium chloride to landfill. Thanks for your answer in advance. I am thinking you may have actually weighed the packet at the end of the experiment but just not included the info in your video.
Good idea. I still have many of those old oxygen absorbers.
One (1) cc of oxygen weighs 0.001429 grams. Many of my tests were able to absorb 1000cc. So, 1000cc x 0.00149 = would equal 1.49 grams. My scale should be able to detect that amount. Some of the oxygen, instead of being absorbed, is converted to CO gas instead.
Phil what would be another good brand Mylar bag and oxygen absorber that I can purchase on Amazon?
I need this answered as well
@@leeanns79 Me too! ☺
I like Pleasant Grove farm (Topmylar.com)
Since the air in the mylar bag is not pure oxygen, it is normal to not see a lot of shrink from the oxygen absorbers. Air is 78 percent nitrogen and only 21 percent oxygen. Oxygen absorbers only remove the oxygen, not the nitrogen and that is okay.
Yup, don't expect the bag to be sucked in.
why do yo ducktape it down? Won't the glue on the tape have moisture in it?
To keep the absorber out of the water. I don't think the tape would have moisture, but the environment, within the jar, would have an increased level of humidity.
Love your attention to detail!
Thank you!
"It pains me doing this to a perfectly good bag..."

How can you tell your Mylar bags are polyester film and not a genuine Mylar bag? I've ordered Mylar bags from Amazon and it's 14 ml thick and made in China. I am wondering whether this is genuine Mylar bag.
DuPont sells very little Mylar to China. In their words "if it's coming from China, it's probable not Mylar" real 2.0 mil Mylar out performs 7.0 mil bags. See this video:
