Inulin is a term applied to a heterogeneous blend of fructose polymers
found widely distributed in nature as plant storage carbohydrates.
Oligofructose is a subgroup of inulin, consisting of polymers with a
degree of polymerization (DP)
10. Inulin and oligofructose are not
digested in the upper gastrointestinal tract; therefore, they have a
reduced caloric value. They stimulate the growth of intestinal
bifidobacteria. They do not lead to a rise in serum glucose or
stimulate insulin secretion. Several commercial grades of inulin are
available that have a neutral, clean flavor and are used to improve the
mouthfeel, stability and acceptability of low fat foods. Oligofructose
has a sweet, pleasant flavor and is highly soluble. It can be used to
fortify foods with fiber without contributing any deleterious
organoleptic effects, to improve the flavor and sweetness of low
calorie foods and to improve the texture of fat-reduced foods.
Inulin and oligofructose possess several functional and nutritional
properties, which may be used to formulate innovative healthy foods for
today's consumer.
