Structure

Maltodextrin consists of D-

units connected in chains of variable length. The glucose units are primarily linked with α(1→4) glycosidic bonds, like that seen in the linear derivative of glycogen (after the removal of α1,6- branching). Maltodextrin is typically composed of a mixture of chains that vary from three to 17 glucose units long. Maltodextrins are classified by DE (

dextrose equivalent Dextrose equivalent (DE) is a measure of the amount of reducing sugars present in a sugar product, expressed as a percentage on a dry basis relative to dextrose. The dextrose equivalent gives an indication of the average degree of polymerisation ...

) and have a DE between 3 and 20. The higher the DE value, the shorter the glucose chains, the higher the sweetness, the higher the solubility, and the lower the heat resistance. Above DE 20, the
