Hemicelluloses are a group of substances which occur in association with cellulose, and are usually a mixture of xylans, xyloglucans, arabinogalactans, glucomannans and galactoglucomannans. Hemicellulose is one of the most abundant polysaccharides after cellulose. Hemicelluloses were used as feedstock for producing sugars. Hemicelluloses are mostly heteropolysaccharides classified according to the sugar residues present, namely xylans, mannans, arabinans and galactans, and they are either linear or branched polymers. Xyloglucan is used as a barrier film [161].
