What does maltodextrin mean?
Maltodextrin is a starch-derived carbohydrate made by breaking starch into short chains of glucose units. It appears in many commercial foods, drinks, and dietary products, where it can function as a sweetener, thickener, carrier, or bulking agent. Its glucose chains are shorter than those of ordinary starch, which can make powdered products dissolve more readily and contribute a light texture. In ingredient lists, the name is often used for ingredients that help carry flavourings, colourings, or other additives. Maltodextrin should not be confused with maltose, which consists of only two glucose units, or with dextrin, a broader term for products obtained by hydrolysing starch. The word belongs primarily to technical, commercial, and food-processing contexts rather than everyday conversation.
nounA carbohydrate made by partially breaking down starch into short chains of glucose units. It is used as a food ingredient, sweetener, thickener, carrier, or bulking agent.
- A starch-derived carbohydrate consisting of short chains of glucose units, used as a food additive, sweetener, thickener, carrier, or bulking agent.
"The nutrition label lists maltodextrin among the ingredients."
"Maltodextrin is often listed as a carrier for added flavourings and other powdered ingredients."
"The drink powder dissolved easily in water because it contained maltodextrin."
Maltodextrin is the quietly useful ingredient that helps powdered drinks dissolve smoothly and gives many foods their light, slightly sweet texture.

Where does maltodextrin come from?
The name is formed from the combining form of “malt” and “dextrin.” “Maltodextrin” was coined as a technical name for carbohydrate products obtained by hydrolysing starch, especially malt and related starches. Its formation reflects the development of carbohydrate chemistry and the use of such products as soluble starch preparations and food ingredients.
How maltodextrin is actually used
The term is mainly used in technical, commercial, and ingredient-label contexts. It is generally neutral, though food-label discussions sometimes associate it with highly processed foods or use it as a general term for starch-derived carbohydrates.
Easily confused with maltodextrin
Dextrin is a starch-hydrolysis product generally containing longer or less narrowly defined glucose chains, whereas maltodextrin specifically refers to relatively short-chain carbohydrates used in food and pharmaceutical applications.
Maltose is the disaccharide composed of two glucose units, while maltodextrin consists of chains containing multiple glucose units.
