Overview
Maltodextrin is a polysaccharide derived from the partial hydrolysis of starch, typically sourced from corn, wheat, or rice. It appears as a white to off-white powder with a mild sweetness and is widely used as a carbohydrate source, texture enhancer, and filler in various food and beverage applications.
Composition and Physical Properties
Maltodextrin consists of glucose polymers of varying chain lengths, classified by its dextrose equivalent (DE) value, which usually ranges from 10 to 20. It has excellent solubility in water, low viscosity, and a neutral flavor profile, making it highly versatile.
Applications and Functional Benefits
Maltodextrin is valued for its ability to:
-
Enhance texture and mouthfeel in beverages, sauces, and dairy products
-
Act as a bulking agent in powdered drink mixes and instant foods
-
Provide a quick and easily digestible source of energy in sports nutrition
-
Serve as a carrier for flavors, vitamins, and minerals
-
Improve moisture retention and shelf life in bakery products
-
Stabilize emulsions and suspensions in processed foods
