The reduced-fat and low-fat mixes containing inulin have similar viscosity and consistency coefficient to the control sample, but they exhibited more Newtonian-like flow behaviour than did the control. In the study of Schmidt et al. [ 29] ice milks made with a carbohydrate-based fat mimicker was found to have. a greater viscosity and consistency coefficient and a smaller. flow behaviour index than those of the control or ice milk made with a protein-based fat mimicker. The rheological properties of the mix were shown to have the largest effect on the hardness of ice cream by Muse and Hartel [. 30 ]. The authors reported that ice creams with high consistency coefficient were very viscous, and this viscosity increased the resistance to penetration by the probe, as similar to our findings.
