Maltodextrin is an easy-to-digest complex carbohydrate made from corn, potato or rice starch using a process known as partial hydrolysis. It is a white, odourless powder that is relatively tasteless and dissolves easily in water. It is often contained in sports drinks to allow athletes to refuel and rehydrate simultaneously during exercise, as it is absorbed as rapidly as glucose. It is also found in a wide range of other foods, where it is used to enhance texture, flavour, and shelf life.
