What is the difference between freeze-dried and dehydrated foods?
Dehydration is a process that includes heating the food and using a fan to maintain airflow to remove the moisture from the food. On the other hand, the Freeze-drying process places frozen foods in a vacuum chamber, and uses low atmospheric pressure to remove the moisture from the food in a vapor state. Because the freeze-drying process does not require hot temperatures, the nutrient level and flavor are of higher qualities than dehydrated products. Freeze-dried foods maintain their structure and texture. The removal of moisture gives it a longer shelf life.
