The sucralose/polydextrose mixture has been shown to be
a suitable sucrose replacement for low-sucrose reformulated
muffins. Replacement of 25% sucrose by a mixture of PD-SC altered
none of the eating quality properties of the reformulated muffins.
Further replacement of sucrose by PD-SC progressively affected the
batter structure, both before and during the baking process. As the
sucrose was replaced the viscosity and viscoelasticity of the raw
batter decreased, as did the structure setting temperature. These
circumstances do not favour appropriate bubble expansion, even
though the PD-SC batters had an appropriate initial number and
distribution of air bubbles. The result was a muffin with less height
and fewer final air cells as the sucrose was replaced, and with low
hardness and springiness. The sensory acceptability results indicated
that sucrose can be replaced up to a level of 50% with good
