traditionally dry ice(solid state of CO2) has been used in the "redneck" long term storage process from at least back in the 60's... I probably fit the term, even though I went to a reputable school in the South... does anybody have a technique for doing a single bucket at a time storage?...pruging with nitrogen or CO2 from a gas cylinder?...I'd like to do a full bucket of popcorn after I freeze the corn to kill off any weevil eggs...using the vacuum sealer is not volume efficient..
