Overview

From Wikipedia, the free encyclopedia · Read full article · Text CC BY-SA 4.0

Inulins are a group of naturally occurring polysaccharides produced by many types of plants, industrially most often extracted from chicory. 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.
