Solar dehydration is a method of preserving food by removing moisture using sunlight. This process involves placing fruits, vegetables, or herbs in a solar dehydrator, which is designed to capture and retain heat from the sun. As the temperature rises, moisture evaporates, preventing spoilage and extending shelf life. The benefits of solar dehydration include energy efficiency and cost-effectiveness, as it relies on renewable energy from the sun. This technique is particularly useful in regions with abundant sunlight, allowing for the preservation of seasonal produce and reducing food waste while maintaining nutritional value.
