500cc Oxygen Absorbers for Food Storage - 100 Count (20x Packs of 5) - for Long Term Food Storage & Survival, Mylar Bags, Canning, Harvest Right Freeze Dryer, Dehydrated, and Preserved Foods

I've been using these long enough to be certain of this: an O2 absorber in the package helps to extend the life & taste of stored food considerably.I don't use plastic vacuum bags often; they're wasteful and they crush many foods. Instead, I use Mason-style jars and a vacuum lid attachment. The attachment lets you use your vacuum pump to remove the air from the jar, then the regular mason lid makes a seal when you remove the hose. Works great. Doesn't crush things like dried fruit, and you can vacuum and freeze liquids like soup without a vacuum chamber.A one qt/one liter jar with one of a couple of O2 absorbers will extend the life of food months beyond typical storage time. I've stored dried apples at room temp for nearly a year, and they are still "fresh" (as fresh as an apple slice that was dipped in ascorbic acid and then dehydrated can ever be...). I've tried both ways, with and without the O2 absorbers. The 02 absorbers make a noticeable improvement in taste.Food with high fat content, like nuts, will eventually always go rancid at room temp, but I store walnuts with with O2 packets and vacuum at room temp, and they consistently last 6-9 months after removing from the original packaging. That's months more storage time than I used to get when I just took the nuts out of the original package and put them into an air-tight container.

These oxygen absorbers 500 Are an excellent value if you are canning in mylar bags to place and 5 gallon buckets. They’re comparable to other companies and price. I’ve had very few failures. Unlike others, I have never noticed an off smell to using oxygen absorber.

These are as described .Awesome product , worth buying .Especially for dry canning and much more when it comes to elimination of moisture.My foods stay fresh like I'd expect.You can't go wrong!

Used for food storage. 4 to 50lbs.

Very good o2 absorbers and work very well with freeze dried food when put either in jars or mylar bags.

They are great , fast shipping

The packaging on these oxygen absorbers is top-notch! The entire set of 100 absorbers is vacuum-sealed, and inside that, there are 20 smaller vacuum-sealed bags, each containing 5 absorbers. This keeps them fresh and makes it easy to use only what’s needed without wasting any.

Works well.
