Many pet foods contain sugars. Some for taste (dogs do have a “sweet tooth”), but more often for functional reasons. For example, in semi-moist foods we use sugars such as glycerol and propylene glycol, or syrups from corn or sugar beets as humectants. There is another class of sugars that are used extensively in the human foods industry, but seldom in pet foods, that might provide benefit under special food and nutritional circumstances. These sugars are the maltodextrins.
