Inulin is a type of fermentable fiber that is found naturally in the roots of many foods, such as whole wheat, onions, garlic, and artichokes, and is commonly extracted from chicory root and added to foods
Inulins are a group of naturally occurring polysaccharides produced by many types of plants, industrially most often extracted from chicory. 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.
Inulins are polymers composed mainly of fructose units (fructans), and typically have a terminal glucose.
