I finished sealing some foods- beans, rice, etc in Mylar bags with O2 absorbers in 5 gal paint buckets. Now I am wondering if I should put them outside for a couple of days of hard freezing to be sure any potential for insects is gone. From what I have read I should have frozen the supplies then sealed, but what's done is done. Would freezing now cause moisture problems? My thinking is they are sealed and the moisture level shouldn't change. Does anyone have any experience with this? Thanks!
