ABSTRACT: Physicochemical properties of fructan inulin produced from Acetobacter species and natural inulin were investigated. From cryscopic method, the molecular weights have been found 5010 gmol-1. for bacterial inulin and 4700 gmol-1. for natural inulin. The determination of branches for both kinds of inulin indicates that both polymers are beta-(2®1) linked polyfructan with 6.0% and 4.4% beta (2®6) branches for bacterial inulin and natural one, respectively. Moreover, the spin-lattice relaxation times (T1) for bacterial inulin was lower than that of natural one. This result indicates a great order of protons in bacterial inulin.
