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

Great Price and lots to spare

Large sized moisture absorbers that can be “ recharged “ with heat from an oven or microwave. I use these in my dry cat food container to keep the food fresh. No complaints from kitty.

These work well and are a good buy.

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.

The packaging is perfect so there’s not as much waste. But there are no oxygen indicator dots to tell you whether they are expired or not.

These are really good for a bit bigger size freeze dried items.

I started these last week when I was repackaging some rice and other food for long-term storage and had Red. It was recommended to use these. I think they will work just fine. I added them too many bags of rice.

Product arrived on time and as ordered....always satisfied with this vendor
