**2. Inulin**

Inulin is an allocated polysaccharide mixture composed of α-d-glucopyranosyl-[β- (2,1)-d-fructofuranosyl]-d-fructofuranosides linked by β-(2,1)-d-fructosyl-fructose

bonds, and each of this chain is terminated by fructose moiety. The linking and bonding in inulin moiety are designated in **Figure 1**. Inulin is a reservoir of nondigestible carbohydrate known as fructans. It constitutes the bulk of glycosidic bonds joining fructosyl-fructose. The inulin-type fructans stored in Dicotyledonous species are connected with linear β(2→1) fructofuranosyl units, whereas monocots encompass branched complex-type fructans [2].
