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 white hygroscopic spray-dried 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 is sometimes used in brewing to increase the specific gravity of the final product.This improves the mouth feel of the increases head retention and reduces the dryness of the drink. Maltodextrin has no flavor and is not fermented by yeast, so it does not increase the content of the brew. It is also used in snacks such as some potato chips. It is used in "light" peanut butter to reduce the fat content but keep the texture (as in light Peanut Butters).
Maltodextrin is used as an inexpensive additive to thicken food products. It is also used as a filler in sugar substitutes and other products.
