Throughout history, fruit drying is one of the most widely used techniques for food preservation.
We have references to raisins being dried in the Phoenician era. The fruits were sun-dried, a process also used to preserve meat and fish to provide a means of subsistence during times of food shortages.
This preservation technique seeks to preserve food quality by lowering water activity through moisture content, thus preventing deterioration and microbiological contamination during storage.
Various dehydration methods can be used, such as solar drying, hot air drying, spray drying, low temperatures, etc.
