Maltodextrin
All rights reserved.
Maltodextrins (e.g. Maltrin, Grain Processing Corporation) are polymers
of dextroses, made from natural corn starch. The starch is cooked, and
then acid and/or enzymes are used to break the starch into smaller
polymers (a process similar to that used by the body to digest
carbohydrate). Maltodextrins do not contain significant quantities of
protein, fat or fiber.
There are different grades of maltodextrins based on the DE values. DE
= dextrose equivalents, a quantitative measure of the degree of starch
polymer hydrolysis. The higher the DE, the greater the extent of starch
hydrolysis. Thus, higher the DE, the sweeter it is. Maltodextrin with a
DE of 18 is approximately 1/4 as sweet as sucrose. [2]
Diabetics should follow the advice of their physicians. Its glycemic index
is metabolically equivalent to glucose (dextrose). Maltodextrins are also
called glucose polymers.
Maltodextrins are excellent solids builders for standard and low-fat
products. They are effective spray-drying aids for flavors, fruit juices,
and other hard-to-dry products. They also are easily digestible
carbohydrates for nutritional beverages.
Maltodextrin can also be used as a thickening agent in a number of
sauces and salad dressings.
Maltodextrin always appear in "weight gain supplements". It is digested
easily and provide calories.
