vacuum storage in jars

I have vacuum stored some things in 1/2 gal Ball jars using a foodsaver vacuum attachment. I have found no info on how long this will store as opposed to open air. Has BYU or anyone else done any studies on this? It would be logical that they should store longer because of the small amount of oxygen that would be available in the jar to react with the food. I realize that if you added a small oxygen absorber to the jar it would be good for 30 years and I do not expect that but I would think 10 or 15 years should be reasonable. Anyone have any thoughts??

I do this too. Heard from someone that brown rice was fresh tasting after 13 years. You need to eat the contents quickly because it will turn rancid not too long after opened. My friend has fun vacuuming marshmallows in the jars. I have done a lot of nuts...raw.

Thanks for the reply. I too seem to remember the brown rice episode after you reminded me. I felt and feel that the dry beans, powdered milk, and candy that I have packed tis way should be good for at lest 15 years. At my age that is all I care about.

I really hope my candy especially keeps a long time! The good thing about sealing it in jars is I won't open those jars because it's not "the emergency!" ;-) LOL

I use this method for leftovers from #10 cans. Dried carrots, celery, onions, powered milk, mac and cheese, etc. I still open them on occasion when I've needed a handful, then sealed them back up again. I can't speak to oxygen degradation, but it keeps air moisture from turning them into a solid mass in a month. I've had the carrots and such in jars for at least 18 months and they're still fine.
