Abstract: Inulin hydrolysis catalyzed with strong acidic cation resins as solid acid was studied.A high fructose syrup with high quality was obtained after being vacuum concentrated.The optimal conditions for inulin hydrolysis are:D061 strongly acidic cation resin as solid acid,the ratio of solid acid to inulin solution(20%) 1:3,hydrolysis temperature 75 ℃ and hydrolysis time 120 min.Hydrolysis rate of inulin with this method is 92.1%.Desalting from inulin solution is one of the key technologies for continuous inulin hydrolysis with solid acid.

Key words: inulin, hydrolysis, solid acid, high fructose syrup
