Industrial production of difructose anhydride III (DFA III) from crude inulin extracted from chicory roots using Arthrobacter sp. H65-7 fructosyltransferase

A practical, economical, and industrial process for the enzymatic production of difructose anhydride III (DFA III) was investigated for crude inulin prepared from chicory roots using Arthrobacter sp. H65-7 fructosyltransferase. A comparable level of DFA III production to that from commercial inulin was obtained using crude inulin, suggesting the feasibility of this production process.
