摘要：Bamboo culm (Dendrocalamus giganteus Munro) was treated with hot water in non-isothermal conditions (140, 160, 180 and 200 degrees C) for various reaction times (10, 30, 60 and 120 min) to generate xylo-oligosaccharides in a batch reactor at a solid to liquor ratio of 1:10 g/g. The influence of reaction conditions on yields, compositions and characteristics of the products were evaluated. The maximum yield of xylo-oligosaccharides of 47.49% was achieved at 180 degrees C for 30 min with a relatively low level of xylose (4.73%) and other products (arabinose 0.20 g/L, galactose 0.19 g/L, HMF 0.15 g/L, furfural 0.36 g/L, acetic acid 0.64 g/L and formic acid 0.26 g/L). Higher temperature and/or longer reaction time reduced the yield of oligosaccharides, and enhanced concentrations of monosaccharides and byproducts. The result demonstrated that the yield of xylo-oligosaccharides obtained by autohydrolysis depends on the reaction temperature and time. (C) 2013 Elsevier Ltd. All rights reserved.
