Freeze-dried meat is a type of food that has had most of its moisture removed through a special process. This method involves freezing the meat and then slowly heating it in a vacuum, which causes the ice to turn directly into vapor. As a result, the meat becomes lightweight and can be stored for long periods without refrigeration. This preservation technique helps maintain the meat's flavor and nutritional value. Freeze-dried meat is popular among campers, hikers, and emergency preparedness enthusiasts because it is easy to pack, quick to prepare, and has a long shelf life.
