Non-cellulosic heteropolysaccharides from sugarcane bagasse – Sequential extraction with pressurized hot water and alkaline peroxide at different temperatures.

Highlights: [•] Xylans were extracted from sugarcane bagasse with hot-water and alkaline peroxide. [•] Xylose units in the main chain of xylans are substituted by arabinose at C2 and C3. [•] The arabinoxylans extracted with water at high temperature contained less arabinose. [•] The water-soluble arabinoxylans are more branched, acetylated and low-molar-mass. [•] Water-extracted hemicelluloses contain more lignin than alkaline peroxide extracted. [ABSTRACT FROM AUTHOR]
