Fructo-oligosaccharides (FOS)

Description

Fructooligosaccharides (FOS), considered as inulin-type fructans, represent an important source of prebiotic compounds that are widely used as an ingredient in functional foods. FOS are produced by the action of fructosyltransferase from many plants, fungi and bacteria, and they are mainly composed of *-kestose, nystose, and *-beta-fructofuranosyl nystose. Among them, *-kestose has better therapeutic properties than those with a high polymeric degree (GF(n > 4)). FOS exhibited properties than those with a high polymeric degree (GF(n>4)). FOS exhibited properties such as low caloric values, non-cariogenic properties, decrease levels of lipids and cholesterol, help gut absorption of ions, and stimulate the bifidobacteria growth in the human colon.
