Abstract: Arabinoxylan is a hemicellulose found in cell walls of plants including woods, cereal grains, husk and others. It is comprised of two pentose sugars, arabinose and xylose. Maximum amount of arabinoxylans is present in psyllium husk; a papery layer around psyllium seed. The seeds of monocots contain it in cell wall while the most part  is comprised in their endosperm. The yield of arabinoxylan is different ranging between 5 to 8% in whole wheat flour (w/w) and 6·40 to 6·93% in dry malts whilst psyllium husk comprises more than 60% (w/w). The arabinoxylan in psyllium husk is branched molecule additionally comprising of rhamnose (3–5%) and galacturonic acid (5–8%) unlike its other sources. Moreover, the molecular structure of arabinoxylans from psyllium husk makes it gel forming non-fermentable and non-digestible and cereals  contain fermentable arabinoxylans that are digestible. Arabinoxylans is partly degraded in malting process. Physiocochemical response exhibits that light coloured products are obtained when added in wheat flour along with improved rheological properties. Arabinoxylans is active to prevent and cure various ailments. These characteristics make this substance vital for functional foods and nutraceutical products. Arabinoxylans the active ingredient in Psyllium husk had imperative physiological functions: working as laxative, manages serum lipid profile in hypercholesterolemic people, decreases glucose and Hb A1c concentrations in patients with type 2 diabetes. The arabinoxylans addition in meal, functional food and its administration in nutraceutical products can provide better healthy human livings. The existing literature indicates the research outcomes related to yield, structure, composition and physicochemical response of arabinoxylans exclusive from psyllium husk.
