One way to avoid all these problems would be to explore the possibility
of freeze drying. You need a source for -40 temperature, and some vacuum
Freeze drying has been used to keep bacterial strains viable for over 10
years at room temperature.
Since you probably just want the gooey juices, why not try drying with
mild heat and reconstituting in a blender with water?
This sounds like more fun than slamming it in the fridge anyway
