title: Isolation and characterization of a xylan with industrial and biomedical applications from edible açaí berries (Euterpe oleraceae).
abstract: The chemical features of xylan largely determine its physical and biological properties and its use in the industry. In this work, we describe the occurrence, purification and partial characterization of a xylan in edible açaí berries (Euterpe oleraceae), using a fairly simple and inexpensive method of purification from alkaline açaí extract. A mainly linear (1→4)-β-d-xylan was found as the majority (70%) of alkali extract and 4.2% of the dry matter açaí pulp. This represents the biggest source of xylan found so far in a fruit pulp and could be suitable for applications in the industry and biomedical field.
