Inulin is a commonly used prebiotic ingredients for functional food formulation. The effect of inulin on the gelation properties of whey protein was investigated using whey protein and inulin (WP/inulin) and polymerized whey protein and inulin (PWP/inulin) mixtures at different levels of protein (4-8%, w/v) and inulin (1-5%, w/v). WP/inulin mixture was prepared by heating protein and inulin together while the latter by heating protein alone and then mixed with inulin. Both mixtures were analyzed for turbidity, zeta potential, particle size, and rheological properties. Dispersions became more opaque with increasing protein but there was no significant difference between the two mixtures. A small shift towards larger size and significantly decreased negative zeta potential with increasing inulin addition (1-5%) were observed for both mixtures. WP/PWP and inulin mixtures exhibited a shear thinning behavior. Transition temperature of whey protein increased with inulin addition. WP/PWP and inulin mixtures were induced into cold-set gels by calcium and the gels were analyzed for hardness. Hardness of WP/PWP and inulin gels increased with the increasing inulin. Results indicated that interactions between whey protein and inulin had impact on the gelation properties of whey protein regardless the way inulin added.

The aim of the study was to assess the possibility of using polysaccharides: inulin and polydextrose in combination with steviol glycosides as sucrose substitutes in starch-based desserts with reduced sugar content and to determine their influence on the rheological properties of these desserts. The samples (starch-milk desserts) were prepared from native potato starch, milk, dye, flavouring agent, and sucrose. The sucrose was partially or completely substituted with steviol glycosides and inulin or polydextrose. The rheological evaluation of the desserts was performed by determining pasting characteristics, viscosity curves, creep and recovery curves and mechanical spectra. Substitution of sucrose with prebiotic polysaccharides modified the rheological characteristics of the starch-milk desserts to a degree depending on the type and level of the substituting agent. Inulin reduced the peak viscosity of starch-milk paste, while it had no effect on the final viscosity of the product, contrary to polydextrose, which increased value of the latter parameter. The desserts exhibited a non-Newtonian, shear-thinning flow behaviour. The use of inulin, in both the highest and the lowest concentrations, significantly changed the consistency coefficient and the flow index values, while such a phenomenon was not observed in the case of polydextrose. The desserts with inulin showed increased values of the storage modulus and reduced susceptibility to stress, manifesting strengthened viscoelastic structure. The results indicate that the both prebiotic polysaccharides can serve as substitutes for sucrose in desserts with reduced sugar contents.
