This paper examines the effects of processing conditions and starting materials on the viscoelastic behavior of Nu‐TrimX (a new β‐glucan‐rich hydrocolloid product) suspensions (5% by weight in deionized water). In general, Nu‐TrimX suspensions exhibit clockwise thixotropic loops with shear‐thinning behavior over the experimental shear rate range (0–250 s −1 ) at 25C. The rheological responses of the various Nu‐TrimX suspensions were modeled using a power law constitutive equation. The suspensions behave as pseudoplastic materials with power law exponents ranging from 0.42 to 0.71.
