Abstract
Described herein is a method for crystallizing aspartame (APM) by cooling an aqueous solution containing APM without forced convection during part of the crystallization, wherein a clear aqueous APM solution is initially cooled under forced convection and forced convection is interrupted, after crystallization has started but before the concentration of the APM crystals formed in the system reaches 0.5% by weight, until the amount of crystals reaches at least 10%, but not more than 50%, of the target amount, and wherein cooling is interrupted for at least part of the time of said interruption of forced convection at about the same time or shortly thereafter.
