Dehydrated products are food items from which most of the natural moisture has been removed through controlled drying methods such as air drying, sun drying, spray drying, or freeze-drying. This process preserves the food, extends shelf life, and reduces weight and volume, making storage and transportation easier. Dehydrated foods retain much of their flavor, aroma, and nutrients, and they are widely used in packaged foods, ready-to-eat meals, and seasoning mixes.
