Oct 07, 2021 Taking into account how a freezer and freeze dryer work, the next big difference between the two is the quality of the food. When food is frozen, the water inside it will expand and turn into ice. This can damage the cell walls of the food. So, this is why the texture and flavor of frozen food can change when it’s defrosted.
