Question.
Does vacuum sealing work the same as oxygen absorbers?
I have the vacuum sealer attachment for my food saver and use it. I always wondered how it compared to other ways of removing oxygen from items. I use canning jars for my vacuum sealed dry goods.
Probably quite. O2 absorbers are usually used with Mylar bags. Food saver bags aren't as impermeable.
The foodsavers get down to about 20hg of vacuum. I had a vacuum pump made for servicing auto air conditioning that would get down close to 30hg which is about as much as can be obtained on earth. Still not quite like the vacuum/void of outer space. Throw enough O2 absorbers in a Mylar bag and you could probably get close to 30hg but I doubt foodsaver bags would hold up.
Food savers work better than squishing the air out of a ziploc bag though. They double freezer storage time which is their main purpose. I'm sure using them on jars or other containers helps but I don't know how much time it adds. Probably depends on the contents. 1 1/2 to 2 times the storage time probably.
