Interpretive Summary:

Technical Abstract: The ability to predict the rheological performance of various biopolymers is an important tool in optimizing processing procedures in the food industry. The rehological properties of cellulosic gel dispersions were investigated using stress relaxation, small-amplitude oscillatory shear, strain jump, and steady-state shear experiments. The constitutive models were fitted using stress relaxation data and the predictions of the models were compared to the experimental data. The cellulosic fiber gels used in this study represent a new generation of no-calorie fat replacers denoted as Z-Trim. The gels were prepared from maize hulls by chemically and physically treating the pericarp cell wall substrate in a multistage process to disintegrate their morphological cellular structure. The presentation will discuss the rheological behavior of the cellulosic fiber gels and the viability of the various constitutive models to describe the measured flow behavior.
