520			_aJerusalem artichoke (Hefianthus tuberosus L.) has been reported to have one of the highest carbohydrates yield. The main carbohydrate component in Jerusalem artichoke tubers is inulin, with high fructose content (about 94%). Inulin is a fructose polymer which has been widely investigated for the production of high-fructose syrup by acid or enzymatic hydrolysis. In this work, a process optimization study to extract of inulin at different temperatures, time and solvent solid ratio were used. The optimal conditions for maximum inulin extraction yield were (68.70 %) at 85°C, 60min and water solid ratios 1:20 (v/w). Precipitation of inulin by four solvents (ethanol, propanol, acetone and acetonitrile) at different ratio 1: 1, 2: 1, 3:1 and 4: 1(solvent: supernatant v/v) were studied. Inulin precipitation by ethanol and acetone were more than that occurred using acetonitrile or propanol. The influence of pH, type of acid, temperature and time on hydrolysis of inulin were investigated. The complete hydrolysis of the inulin was attained at pH 2.0, adjusted with sulphuric acid after 90min at 100°C.
