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.

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.
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.
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.
Thank you! I have wondered about quality of the items I buy, I am so not a math person when I was younger. I am pretty much house bound as a caregiver and have taken up reading books on finance, that was life changing. This example is like a person telling me how great he/she is without a resume. Thank you again.
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!
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!
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

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.

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?
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.
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.
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.
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.
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.
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
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.
Thank you for this video. Very informative. I have never thought of doing oxygen absorber test like you did. I have been using pack fresh USA for over a year. Have you ever tested them?
@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
This was very interesting to watch. I’m happy that they seem to be putting out a good product. I also order from Top Mylar, and Pack Fresh USA. Any chance you could do a test on PF USA Mylar and absorbers?
I've been happy with Pack Fresh USA so far. They always have worked well. But it's odd that the Mylar bags and oxygen absorbers I buy from them are shipped to me from Canada. I don't mind, but it doesn't jive with "USA" in their name.
I would never us a 7mil bag. 10mil minimum. What they advertise is both sides. a 7 mil advert is only 3.5 each side. Not bueno amigo. However, this is the first time I've seen the advertised mil is for only 1 side. I've never seen this in all the bags I've bought. Maybe I should switch to this brand. I'll do a little more research, but looks promising. Thanks for all your work brother
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
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.
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’re freaking awesome ❤️ Every day I check your channel to see if you’ve uploaded The main thing I’m keeping an eye on is exactly this, Mylar bags oxygen absorbers and freeze drying I’m thinking about freeze drying ground beef but not sure which beef I should buy 73/27, 80/20, or 90/10 I know the beef with less fat costs more but fat doesn’t freeze dry good and I need to make sure to remove as much as possible but I also want good flavor not cardboard taste lol I love the McCormick taco seasoning but is that good for long term? Which beef would you suggest?
Fat is flavor. With that said, I've done 90/10 and 80/20. I've cooked it well, and then I used a clean towel, placed the beef on the towel, rolled it up, and then wringed the towel. This got almost all the fat out of the beef. I hope you found the problems with your FD.
@@Philat4800feet I should be freeze drying by the end of this week Electrician is going to install a dedicated outlet for my freeze dryer Really stressed me out to have to hire someone to come into my home and see my stock and freeze dryer They should be back tomorrow to finish that and do other electrical work in my kid’s rooms I hope in the future I won’t regret this decision but we really needed it done 😥 First thing I’ll freeze dry after my bread run will be beef because I don’t think I want synthetic beef in the future lol
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 🙏🏽
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..
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.
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.
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.
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!
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.
Many thanks for this video and so many others. Hubby and I learn so much from them and sincerely appreciate all your time and expertise to produce them. If memory serves, it seems you recommended to someone in Canada - who was facing difficulties obtaining Mylar bags during COVID or even during more recent shipping/supply stagnations - that a possible place to obtain Mylar [polyester] bags would be a local Home Storage Center of the Church of Jesus Christ of Latter-day Saints. Since Harvest Right sometimes takes 3 weeks or so to send supplies - especially if they're temporarily out of stock - hubby & I are curious to know if you've ever tested the Home Storage Center's Mylar [polyester] bags and O2 packs and how they compare with those sold by Harvest Right. For years, we've used the bags and O2 packs from the Home Storage Center for other basic dehydrated food storage items so I'm thinking they most likely are high quality. While we realize the Home Storage Center isn't a commercial enterprise and exists to help folks with basic food storage items, it's always good to explore all options for purchasing bags and O2 packs. Thanks!
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.
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)
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.
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.
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.
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.

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!!
Thank you for your comments
This is fantastic. I will be showing it to my homeschooled kids
Have you seen this video?
ua-cam.com/video/vzichaBdDfs/v-deo.html
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.
Glad it was helpful!
Thank you for your detailed testing and great information.
Kind words
Love your attention to detail!
Thank you!
Wow fantastic video! Thank you.
WOW just wow thank you so much for taking the your time.
Kind words
I enjoyed this. I use HR products and have often wondered about their quality.
Thank you! I really appreciate you hard work😊
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.
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.
Wow! What a great teacher! Thank you!
You are so welcome!
Well done Phil as usual. Thank You.
More to come
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.
Fantastic video. THANK YOU, PHIL!
Many thanks!
I just found your channel. Wow this was great info!! I subscribed!
Welcome aboard!
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.
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
Do they feel like flour or sand inside?
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.
Thank you for this video. Very informative. I have never thought of doing oxygen absorber test like you did. I have been using pack fresh USA for over a year. Have you ever tested them?
I believe Pleasant Grove Farm is selling PackFreshUSA
@@Philat4800feet I buy from PackFreshUSA too.. My other go to source for bags & oxygen absorbers is Azure Standard.
Awesome video for us nerd consumers wanting to know the real world specs and performance of products!
Thanks you
Wow! That was just plain cool! Thank you sir!
Glad you liked it!
@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
Thank you so much, big help. 👍
This was very interesting to watch. I’m happy that they seem to be putting out a good product. I also order from Top Mylar, and Pack Fresh USA.
Any chance you could do a test on PF USA Mylar and absorbers?
Soon.
I've been happy with Pack Fresh USA so far. They always have worked well. But it's odd that the Mylar bags and oxygen absorbers I buy from them are shipped to me from Canada. I don't mind, but it doesn't jive with "USA" in their name.
I would never us a 7mil bag. 10mil minimum. What they advertise is both sides. a 7 mil advert is only 3.5 each side. Not bueno amigo. However, this is the first time I've seen the advertised mil is for only 1 side. I've never seen this in all the bags I've bought. Maybe I should switch to this brand. I'll do a little more research, but looks promising. Thanks for all your work brother
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!
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.
I guess you could. My recommendations where based on food safety from the FDA/Health Departments.
I WASTED $6500 MY FREEZE DRYER NEVER WORKED WRIGHT.CUSTOMER SERVICE IS THE WORST....
@@ashyslashy5818 Would your share your problems with me? I'd love to see you be a happy freeze drier.
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’re freaking awesome ❤️
Every day I check your channel to see if you’ve uploaded
The main thing I’m keeping an eye on is exactly this, Mylar bags oxygen absorbers and freeze drying
I’m thinking about freeze drying ground beef but not sure which beef I should buy
73/27, 80/20, or 90/10
I know the beef with less fat costs more but fat doesn’t freeze dry good and I need to make sure to remove as much as possible but I also want good flavor not cardboard taste lol
I love the McCormick taco seasoning but is that good for long term?
Which beef would you suggest?
Fat is flavor. With that said, I've done 90/10 and 80/20. I've cooked it well, and then I used a clean towel, placed the beef on the towel, rolled it up, and then wringed the towel. This got almost all the fat out of the beef. I hope you found the problems with your FD.
@@Philat4800feet
I should be freeze drying by the end of this week
Electrician is going to install a dedicated outlet for my freeze dryer
Really stressed me out to have to hire someone to come into my home and see my stock and freeze dryer
They should be back tomorrow to finish that and do other electrical work in my kid’s rooms
I hope in the future I won’t regret this decision but we really needed it done
😥
First thing I’ll freeze dry after my bread run will be beef because I don’t think I want synthetic beef in the future lol
@@Philat4800feet so essentially, as low fat as possible?
@@lat1419 Yup. Remove as much fat as possible to avoid rancid foods
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
Excellent video!
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.
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?
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.
Very helpful analysis!
Shalom! I just discovered you this morning. I am quite impressed, sir. Thank you so much. Blessings in Yeshua’s name.
Thank you kindly
CHRIST SAID HIS NAME IS CHRIST.
@@ashyslashy5818 He said "I AM WHO I AM"
@@ashyslashy5818 He goes by many names.
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.
Thank you so much for doing this!
More to come.
Very interesting.
Thank You!
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.
I learned a lot, thanks
Thanks Phil! You're the bomb!
Blush
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
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.
Great informative video. Thank you.
Glad it was helpful!
Amazing video!!
Thank you. Much appreciated.
Many thanks for this video and so many others. Hubby and I learn so much from them and sincerely appreciate all your time and expertise to produce them.
If memory serves, it seems you recommended to someone in Canada - who was facing difficulties obtaining Mylar bags during COVID or even during more recent shipping/supply stagnations - that a possible place to obtain Mylar [polyester] bags would be a local Home Storage Center of the Church of Jesus Christ of Latter-day Saints.
Since Harvest Right sometimes takes 3 weeks or so to send supplies - especially if they're temporarily out of stock - hubby & I are curious to know if you've ever tested the Home Storage Center's Mylar [polyester] bags and O2 packs and how they compare with those sold by Harvest Right. For years, we've used the bags and O2 packs from the Home Storage Center for other basic dehydrated food storage items so I'm thinking they most likely are high quality.
While we realize the Home Storage Center isn't a commercial enterprise and exists to help folks with basic food storage items, it's always good to explore all options for purchasing bags and O2 packs. Thanks!
Funny you mentioned this. I'm in the middle of test right now. Should be done soon.
Phil, thank you for this info. Did you happen to test any of the OA from Uline? You can buy 2000 300CC OA for $160.00, .08 each.
Not yet. I need to find out where U-line get theirs
I have some uline oxygen absorbers and clay desiccant. Also some Impak Mylar bags. I would be willing to send to you for testing. Let me know.
@@ryam8962 Thanks for the offer, however, it need to be a blind and random sample.
Thank you for this information. And you know what...thank you again just because =)
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 u
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.
Nice review thanx. btw does it state where the mylar bags are made?
Nope, no one wants to give up that information or doesn't know.
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.
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.
great video!
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!
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.
Thanks, very informative.
Awesome methods for testing thanks 👍🏼
You bet!
You just gained a sub sir very nice, very good information thank you
Thanks for the sub
Very interesting video. However, I believe 4g iron powder times 300cc per 1 gram is 1200 cc not 1600cc
Wow! how did I miss that! Too late for an edit. Thanks for the catch.
@@Philat4800feet then delete and redo.
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.
So good to know. Thanks
I have used their Food Saver and mylar bags. no complaints.
Nether do I. This series is to show other options
THANK YOU FOR DOING THIS!
You smart devil. 😉
