Industrial by-products as a sources high-value polisaccharide compounds

Abstract

Agricultural wastes and industrial by-products represent a major origin of carbohydrates. Obtaining hemicelluloses such as arabinoxylan and pectin from these sources presents attractive utilization of waste material. In additions, these polysaccharide products gained much attention because of their excellent biocompatibility, biodegradation and non-toxicity as well as extensive spectrum of their biological and functional properties. Polysaccharides with a molecular weight of about 20 kDa were isolated from the wheat chaff and sugar beet shreds. Obtained pectin produced gel coacervats with gelatin while arabinoxylan from wheat chaff formed a gel by mixing with β-glucan in the presence of laccase. Both of prepared gels under simulated gastric and intestinal conditions indicated a strong stability. Furthermore, biological investigation of extracted polysaccharides revealed good antioxidative activities
