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 consists of D-glucose units connected in chains of variable length. The glucose units are primarily linked with α(1→4) glycosidic bonds. Maltodextrin is typically composed of a mixture of chains that vary from three to nineteen glucose units long.[3]
Maltodextrins are classified by DE (dextrose equivalent) and have a DE between 3 to 20. (The higher the DE value, the shorter the glucose chains, the higher the sweetness and the higher the solubility.) Above DE 20, the European Union's CN code calls it glucose syrup, at DE 10 or lower the customs CN code nomenclature classifies maltodextrins as dextrins.
Maltodextrin can be enzymatically derived from any starch. In the US, this starch is usually corn; in Europe, it is commonly wheat. While wheat-derived maltodextrin may cause concern for individuals suffering from gluten intolerance, maltodextrin is such a highly processed ingredient that the majority of the protein is removed, rendering it effectively gluten free. If wheat is used to make maltodextrin, it will appear on the label. Even so, the maltodextrin itself will be gluten free.[4]
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.
