In a word, yes. We buy large quanities of rice, beans, flour ect. We store them in the freezer for a week prior to storing them in food grade 5 gal buckets with rubber seals, they’ll stay good for years.

I just openned some rice that had a 1985 date on the bucket.

Still good but it was stored in a root celler bucket still in fine shape.

To the un-initiated, a 5 gallon bucket with an o-seal is not something they are likely to come across easily. They would want to look for Gamma-Seal lids, available from Nitro-Pak.
