Plot of the diffusion coefficient versus biopolymer concentration and the light scattering intensity as a function of the distribution in the relaxation times (DRT) for tara gum.

<p>(A) The mean diffusion coefficient (± SEM) of a range of aqueous biopolymer solutions (5–5.0×10⁻⁴ g.L⁻¹) are presented. The c* value (based on the plateau) and the c** value (equivalent to the maximum diffusion coefficient) are indicated by the dotted lines. The graphs represent solutions at different concentration regimes: (B) concentrated, showing a trimodal distribution, while the (C) semi-diluted and the (D) diluted shown a bimodal and a monomodal distribution, respectively.
