Where or when dehydration as a food preservation technique was invented has been lost to time, but the earliest known practice of food drying is 12000 BC by inhabitants of the modern Middle East and Asia.
[1] Dried fruit is fruit from which the majority of the original water content has been removed, either naturally, through sun drying, or through the use of specialized dryers or dehydrators.
Dried fruit has a long tradition of use dating back to the fourth millennium BC in Mesopotamia, and is prized because of its sweet taste, nutritive value, and long shelf life.
Open-air drying using sun and wind has been practiced since ancient times to preserve food.
[21] Fish are also preserved through such traditional methods as smoking and salting.
