Technical Abstract: Z-Trim represents a new source of dietary fiber gels with numerous potential applications in the food industry. This presentation will discuss some of the initial investigations into the rheological behavior of Z-Trim. In particular, the response of the material to thixotropic loop, small-amplitude oscillatory shear flow, and start-up of steady-state shear will be discussed. Z-Trim gels are made from a variety of low-cost agricultural byproducts such as hulls of oats, corn, rice, soybean, and peas, or cereal brans. The viscoelastic response of the Z-Trim materials will be compared to the predictions of linear viscoelastic models. In addition, the effect of the various cellulosic contributing sources to Z-Trim viscoelastic properties will also be discussed.
