The results are given in Table 2. In general, the two fat replacers
improved various preference characteristics of the yoghurt in
comparison with the control. The addition of inulin or polydextrose
significantly (p0.05) affected appearance, color, texture and
overall preference, but no such effect was found for odor or flavor.
Also, polydextrose seemed to yield the product with better sensory
properties, especially when added at higher levels (2e3 g/100 mL).
Sensory textural score was in accordance with physical property
values and it decreased successively with decreases in WHC,
apparent viscosity, firmness and consistency, especially at 3 g/
100 mL addition. Also, the higher appearance scores for the
polydextrose-samples seemed to be related to the lower syneresis
and higher WHC values when compared with the inulin-added
ones.
