Abstract

The invention provides a method of preparing new crystal forms of aspartame utilizing microemulsions comprising: (a) introducing aspartame into a microemulsion formed from an oil phase, an aqueous phase and at least one emulsifier, (b) destabilizing the microemulsion to effect recrystallization of aspartame; (c) separating solid phase crystals from the liquid phase in which they are contained; and (d) cleaning the crystals to remove traces of the oil phase and surfactant.
