First of all, lets define what exactly the freeze drying process is; when a food is freeze dried, first it’s flash frozen at an ultra-low temperature. Next, the moisture is removed via a vacuum process. Because bacteria and other microorganisms need water to survive, freeze-dried foods are preserved in a safe way without the use of chemical preservatives or additives.
The freeze drying process itself preserves the treat naturally, so added chemicals aren’t needed to create a long shelf life. NASA has been extensively using freeze-dried foods to feed astronauts on space missions.
