this study was to discover which rheological profiles are related to greater expected
satiety in semi-solid milk-based snacks. Chocolate flavoured snacks were prepared with four different
hydrocolloids (alginate, carrageenan, hydroxypropyl methylcellulose -HPMC- and xanthan gum) at three
different concentrations. Rheological measurements were carried out in a controlled stress rheometer
using a parallel-plates sensor system. Flow curves were obtained at increasing shear rates (0e200 s1)
and viscoelastic properties were measured using small amplitude oscillatory shear tests. The results
showed that, in general, increasing the hydrocolloid concentration resulted in greater yield stress, viscosity,
thixotropy and viscoelastic moduli, with differences depending on the type of hydrocolloid. For
