Sun-drying is a natural method of preserving food by exposing it to sunlight. This process involves placing fruits, vegetables, or herbs in direct sunlight for several hours or days, allowing moisture to evaporate. The heat from the sun helps to inhibit the growth of bacteria and mold, extending the shelf life of the food. Common items that are sun-dried include tomatoes, apricots, and herbs. This technique is often used in regions with warm, dry climates, where the sun's intensity can effectively remove moisture. Sun-drying is an energy-efficient and cost-effective way to preserve food without the need for artificial additives.
