The results illustrate that the addition of inulin.(A mainly soluble dietary fibre) alters the texture. of yog-ice cream samples. The viscosities of the mixes with added inulin show significant increases. (Figure 1). Consistency indexes (Power Law model with r = 0.91 average confidence of fit) of the. yog-ice cream samples (Figure 1) reveal increases. in the viscosity of yog-ice cream mixes from low. fat to high fat, and in relation to the proportion of. inulin concentration. Increased viscosity in the low fat samples containing inulin can be explained by. the interactions of the dietary fibre and liquid. components of the yog-ice cream mix. Inulin, being highly hygroscopic, would bind water and. form a gel-like network that, in addition to the other. components, would modify the rheology of the mix. Additionally, the use of a viscous acid-formed. protein-gel added as stirred yogurt may contribute to the formation of the ice-cream syste
