Not if they're smart. That's the old way the long term storage companies used to put away dried goods. It didn't work terribly well for several reasons. Mostly because it didn't displace enough O2. Modern O2 absorbers are far more effective than nitrogen or dry ice flushing and that's what they all use now.

 

I think they now use the O2 absorbers because they are cheaper.

I have nitrogen packed grain that has been good after 15 years in the bucket.

The problem I had was the bucket was getting brittle so I opened it up and ate the grain.

It is best to use a food grade bag as a liner for the bucket to hold the grain before using nitrogen. Dry Ice is ok, but I prefered the bottled nitrogen due to easy keeping for later use.

Dry Ice will be gone even if you put it in a freezer.

I have been doing this for the past 20 years of so.

What do you want to know about it.
