ABSTRACT:
The invention relates to a process for the crystallisation of aspartame by neutralising an aqueous solution of aspartame, having a pH of less than 3, with a base and homogenising the solution by means of forced convection, characterised in that the solution is neutralised, and homogenised, in such a manner that the solution obtained is substantially homogeneous and has a pH higher than 3, with the solution no longer being mechanically stirred at least from the beginning of the last second before crystallisation is visually perceptible.
