Maltodextrin is a polysaccharide that is used as a food additive. It is produced from starch by partial hydrolysis and is usually found as a creamy-white hygroscopic spraydried powder. Maltodextrin is easily digestible, being absorbed as rapidly as glucose, and might be either moderately sweet or almost flavorless. It is commonly used for the production of sodas and candy. It can also be found as an ingredient in a variety of other processed foods.

Maltodextrin is a common adjunct to beer brewing to increase the specific gravity of the final beer product. This improves the mouthfeel of the beer and reduces the dryness of the drink.

Maltodextrin is not fermented by the yeast and has no flavor.
