Has Aspartame an Aftertaste?

ABSTRACT Consumer evaluation of the sweetness of aspartame and sucrose solutions at 4°C was undertaken using the “just right” scale. In addition, consumers were asked to comment on the presence or absence of any aftertaste. No significant differences in sweetness ratings were found between the aspartame and sucrose solutions. Both aspartame and sucrose were found to have an aftertaste (perceived by 30% and 60% women and 50% men tested) but the quality of the aftertaste appeared to differ.
