A B S T R A C T The invention relates to a process for the treatment of dried aspartame characterised in that, in a first separation step, particles smaller than 50 µm are removed, with the aid of a stream of air, from aspartame having a particle size distribution with which more than 5 wt.% of the aspartame has a particle size of less than 20 µm and more than 10 wt.% of the aspartame has a particle size of more than 400 µm, and that in a second separation step the product resulting from the first step is subjected to a screening step using a screen that separates at a value between 150 and 250 µm, after which the fraction of the smaller particles thus obtained is recovered as a first product and the fraction of the larger particles is recovered as a second product or is optionally subjected to a further separation step using a screen that separates at a value between 400 and 1000 µm, the fraction of smaller particles thus obtained being recovered as the second product. Aspartame having a particle size distribution with which 97% of the particles is larger than 20 µm and 97% of the particles is smaller than 250 µm appears to present exceptionally good properties as regards processability and dissolution rate.
