The solid-state stability of aspartame hemihydrate (APM) sweetener during thermal treatment is important information for the food industry. The present study uses the novel technique of Fourier transform infrared microspectroscopy equipped with differential scanning calorimetry (FT-IR/DSC microscopic system) to accelerate and determine simultaneously the thermaldependent impurity formation of solid-state APM. The results indicate a dramatic change in IR spectra from 50, 110 or 153°C, which was… Expand
