Maltodextrin Usage And Synthesis

Description Maltodextins are purified, concentrated, nonsweet, nutritive carbohydrates made by hydrolyzing com starch. It occurs as a white, slightly hygroscopic powder, as granules of similar description, or as a clear to hazy solution in water. Powders or granules are freely soluble or readily dispersible in water. A solution of maltodextrin is characterized by a bland flavor, smooth mouthfeel, and short texture, and can partially or totally replace fat in a variety of formulations. Maltodextrins can also be used to replace fats in extruded high fiber cereals and snacks. Theyare currently used commercially for fat replacement in salad dressings, dips, margarine, and frozen desserts. As fat replacers, maltodextrins furnish only four calories per gram, while fats furnish nine calories per gram.

Chemical Properties White powder or solution from partial hydrolysis of wheat or corn starch.

Chemical Properties Maltodextrin occurs as a nonsweet, odorless, white powder or granules. The solubility, hygroscopicity, sweetness, and compressibility of maltodextrin increase as the DE increases. The USP32– NF27 states that it may be physically modified to improve its physical and functional characteristics.

Uses Short-chain saccharide polymers obtained from the partial acid or enzymatic hydrolysis of starch, in the same manner as corn syrup except the conversion process is stopped at an earlier stage. It consists of D-glucose units linked principally by alpha-1,4 bonds, has a dextrose equivalent of less than 20 and basically is not sweet and is not fermentable. It has fair solubility. It functions as a bodying agent, bulking agent, texturizer, carrier, and crystallization inhibitor. It is used in crackers, puddings, candies, and sugar-free ice cream.
