The interaction between aspartame, glucose and xylitol in aqueous model systems of pH 3.00 and containing potassium sorbate was
studied. Potassium sorbate degradation diminished with the increment of aspartame level from 0.050 to 0.500 g/100 g of system. Xylitol
was the humectant that minimized aspartame degradation and non-enzymatic browning development. In general, as expected, presence
of aspartame, xylitol or glucose and their mixtures increased the sweetness and they also diminished the sourness of the systems.
