Inulin formed secondary gelled
structures between casein micelles aggregates, while fructans
tended to deposit themselves on the surface of the casein micelles.
Although the microstructure of the reduced-fat yogurts differed

fructans were perceived by consumers with enhanced sensory attributes in comparison to the
control yogurt. Furthermore, the values of the loss tangent in the
linear viscoelastic region, and of the stress corresponding to the
crossover point between the storage and loss moduli in the nonlinear viscoelastic region, were closely related to the sensory
