Abstract

Se refiere a procesos para la purificación de sucralosa aplicando un procedimiento de purificación sin cristalización inicial, seguido de tres o más pasos secuenciales de cristalización y el reciclado de las aguas madres resultantes de cada paso de cristalización a la alimentación de otro paso de cristalización o purificación. La presente se refiere asimismo a composiciones de sucralosa, así como a composiciones que comprenden las composiciones de sucralosa de la presente. Estas composiciones pueden ser de elevada pureza y presentar un perfil de sabor superior. Reivindicación (1): Un método para purificar sucralosa a partir de una solución de sucralosa en bruto que comprende los pasos de: a) someter una alimentación que comprende dicha solución de sucralosa en bruto a un paso de purificación sin cristalización para obtener una solución de sucralosa de mayor pureza; b) realizar un procedimiento de cristalización en dicha solución de sucralosa de mayor pureza para obtener sucralosa cristalina y aguas madre; c) reciclar al menos una porción de dichas aguas madre a dicha alimentación del paso (a); y d) realizar al menos tres procedimientos de cristalización secuencial adicionales en dicha sucralosa cristalina.
