Abstract
Disclosed herein is a process for preparing difructose dianhydride III (DFA III) comprising reacting inulin with an inulin lytic enzyme derived from a microorganism belonging to Arthrobacter ilicis. The enzyme employed herein efficiently produces DFA III from inulin and is more stable against heat than conventional enzymes. The present process enables industrial continuous production of DFA III. The preferred strain used herein is Arthrobacter ilicis MCI 2297 (FERM P-9893).
