Food Dehydration is the oldest form of food preservation. In the beginning, people used a lot of salt to preserve foods, and they dried their food in the sun or on stove tops. Today we have the food dehydrator to help in the process of drying.

Food dehydration is safe because water is removed from the food. Because water is removed from the food, mold and bacteria cannot grow on it;thus it will not spoil. There is, however, a loss of vitamin A and C in dried foods due to heat and air. It usually takes vegetables 6-16 hours to dry, and fruit 12-48 hours. One can dry fruit and vegetables, and make jerky and fruit leather.
