Inulin has been defined as a carbohydrate consisting mainly of β-(2→1) fructosyl-fructose linkages with a degree of polymerization between 3 and 60 (average ~10) and with a terminal glucose molecule. Due to this particular structure, inulin is not digested by human digestive enzymes, which provides it with prebiotic functions, i.e., stimulating growth and/or activity of health of the host.
