Inulins are a group of naturally occurring polysaccharides produced by many types of plants,[1] industrially most often extracted from chicory.[2] The inulins belong to a class of dietary fibers known as fructans. Inulin is used by some plants as a means of storing energy and is typically found in roots or rhizomes. Most plants that synthesize and store inulin do not store other forms of carbohydrate such as starch.
