Dehydrated food refers to food products that have had their moisture content removed through drying techniques such as air drying, sun drying, or freeze drying. This process preserves the food by preventing the growth of microorganisms and reducing spoilage, while retaining most of the original nutrients, flavor, and aroma. Dehydrated foods are lightweight, easy to store, and have a long shelf life, making them ideal for export, emergency supplies, travel meals, and food manufacturing. Common dehydrated food items include vegetables (like onion, garlic, tomato), fruits (like banana, mango, apple), herbs, spices, and even full meals. These products are widely used in the packaged food industry, catering services, and by health-conscious consumers around the world.
