      Arabinoxylans (AXs) are major dietary fibers. They are composed of backbone chains of -(1–4)- linked xylose residues to which -l-arabinose are linked in the second and/or third carbon positions. Recently, AXs have attracted a great deal of attention because of their biological activities such as their immunomodulatory potential. Extraction of AXs has some difficulties; therefore, various methods have beenusedto increase the extractability ofAXs withvaryingdegrees of success, suchas alkaline, enzymatic, mechanical extraction. However, some of these treatments have been reported to be either expensive, such as enzymatic treatments, or produce hazardous wastes and are non-environmentally friendly, such as alkaline treatments. On the other hand, mechanical assisted extraction, especially extrusion cooking, is an innovative pre-treatment that has been used to increase the solubility of AXs. The aim of the current review article is to point out the health-related effects and to discuss the current research on the extraction methods of AXs.

      Humans are exposed to harmful pathogens and a wide range of noxious substances every day.The immune system reacts to, and destroys, these pathogens and harmful substances. The immunesystem is composed of innate and adaptive immunity, which liaise to protect the host and maintainhealth. Foods, especially cereals, have been reported to modulate the immune response.Arabinoxylans are nonstarch polysaccharides that have been shown to possess immune-modulatory activities. This review article discusses the fundamentals of the immune system andprovides an overview of the immunomodulatory potential of arabinoxylans in conjunction withtheir structural characteristics and proposed similarities with lipopolysaccharides
