N2 - Hydrothermal treatment can be used for the on-farm processing of lignocellulosic materials. This study investigated the hydrothermal treatment of sweet sorghum bagasse (SSB) powder for the extraction of hemicellulose from it. Changes in chemical composition of SSB and the formation of sugars and hydrolytic products were studied. The optimum conditions of 12.54 % (g/g) substrate concentration and 90 min of isothermal treatment residence time at 394 K were conducive to the extraction of 72.61–72.77 % hemicellulose and producing a hydrolysate containing 56.06–63.54 g/L reducing sugars and 5.52–6.80 g/L furfurals. The treated SSB residue contained about 56.30–56.42 % (g/g) cellulose and 31.40–31.43 % (g/g) lignin in it. The substrate concentration and isothermal treatment residence time were significant in the responses observed.
