I haven't seen anything on vacuum packing, although the removal of oxygen is this manner is, IMO, equivalent to mylar bags/oxygen absorber/bucket preparation and storage.
I retrieved some rice for rotation today that was put up in 2/09, prepared for storage by first freezing, then bagging, and storing in 5-gal pails with gamma-seal lids and I'm happy to report it is clean of critters.
The details on our freezing regimen is we froze for at least five days, but not much more; parked on the counter upon removal from the freezer to come to room temp and dry for about three days, and then broke up for bagging and bucketing.
