Dehydrated products are foods that have had their moisture removed, which helps to preserve them for longer periods. This process can involve air drying, freeze drying, or using heat. Common examples include fruits like apples and bananas, as well as vegetables like carrots and potatoes. Dehydration concentrates flavors and nutrients, making these products lightweight and easy to store. These products are often used in camping and hiking meals, as they are convenient and require minimal preparation. To rehydrate, users typically add water, allowing the food to regain its original texture and taste. Dehydrated products are also popular in emergency food supplies due to their long shelf life.
