Rheological properties of the rice bran dietary fiber solution

Using advanced extension rheometer ARES (American TA Company) to study the impact of dif- ferrent factors on rheological properties of rice bran dietary fiber (RDF). The results showed that: Tre- ated under different conditions, RDF solution all showed pseudoplastic fluid properties, which met the power law; the smaller the particle size was, the greater impact on the rheological properties it had; RDF solution viscosity rised with the increasing of concentration, the rheology changed significantly, showing non-Newtonian fluid properties when the RDF concentration was greater than 6%; RDF sol-ution viscosity decreased with the increasing of temperature, the RDF solution viscosity could hardly be affec- ted by NaCl and CaCl 2 at concentration 8%; RDF thixotropy were also studied for providing a good basis to make better use of RDF in the future.
