Thanks. I had read that it produces gas and will cause cans to bulge.
Over the years, very rarely, I have opened older cans of stuff (professionally canned) that have had bulges and promptly thrown it away.
We have canned for yrs with no problems. To store rice and flour—freeze the item for 30 days at 0 F. This kills the bug eggs. Then store in food grade 5 gallon plastic buckets.
Green beans have to be pressure canned to avoid toxic problems. Most everything else can be water bathed.
