Default preservative qualities of CO2?

Don't know where to post this, but it hit me yesterday, when looking for a place to store some rice and beans, that I have some extra airtight containers sitting next to my deep fridge!!
I got 70 pounds of rice in two kegs, and put about 10 lbs of co2 in to purge the o2. Anybody ever done any storage of this type in a keg??

No, but it sounds like it would work.....although plants breathe in c02, I don't know about fungus or bacteria. You might inhibit some nasties but encourage others! Nahhhh it'll work.

I think Nitrogen would be a better option.
Have a beer on me.

nitrogen would indeed work better...and gets used a lot commercially.

a layer of CO2 will still help slow oxidation/staleness a bit though if its all you've got.
I mean, a dime's worth of CO2...its worth a shot!
