InulinInulin is a polysaccharide consisting of a chain of fructose units terminated with a glucose unit. Inulin is stored in the roots of some plants such as Jerusalem artichokes, chicory and dahlias. As inulin is not metabolized in the body it is included in dietary fibre and can be added to food products to increase their content of dietary fibre. It can be used as a texture-improving additive in milk products. Commercially inulin is usually hydrolysed (broken) into oligo-fructans (several fructose molecules in a small chain) or into fructose.
