Oligofructose

Bulking agent, emulsifier, sweetener, prebiotic: Frozen desserts, cookies, energy and granola bars.
Oligofructose, synthesized from sucrose or extracted from chicory roots, consists of up to several dozen fructose molecules linked end to end. Like inulin and other soluble fibers, oligofructose is digested by bacteria in the large intestine, but not by human enzymes. This slightly sweet ingredient provides less than about half as many calories per gram as fructose or other sugar. Oligofructose promotes the growth of "good" bifidus bacteria.
