摘要：
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 acai berries (Euterpe oleraceae), using a fairly simple and inexpensive method of purification from alkaline acai extract. A mainly linear (1 -> 4)-beta-D-xylan was found as the majority (70%) of alkali extract and 4.2% of the dry matter acai 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. (C) 2016 Elsevier Ltd. All rights reserved.
