Abstract

Un metodo para mejorar la estabilidad de cristales de sucralosa que incluye lavar los cristales de sucralosa con una solucion de un regulador en un solvente y posteriormente secar los cristales de sucralosa. El metodo puede utilizarse en un proceso de elaboracion de sucralosa, por ejemplo para ayudar a superar problemas de estabilidad de sucralosa que resultan de la extensa exposicion de las soluciones de sucralosa a altas temperaturas. Reivindicacion 12: Un metodo para producir sucralosa cristalina, que comprende los pasos de: desacetilacion de un sucralosa-6-acilato para producir sucralosa; recuperacion de la sucralosa como cristales de sucralosa; lavar los cristales de sucralosa con una solucion de un regulador en un solvente; y posteriormente secar los cristales de sucralosa para formar dicha sucralosa cristalina.A method for improving the stability of sucralose crystals that includes washing the sucralose crystals with a solution of a regulator in a solvent and subsequently drying the sucralose crystals. The method can be used in a sucralose manufacturing process, for example to help overcome sucralose stability problems resulting from the extensive exposure of sucralose solutions at high temperatures. Claim 12: A method of producing crystalline sucralose, comprising the steps of: deacetylation of a sucralose-6-acylate to produce sucralose; sucralose recovery as sucralose crystals; wash the sucralose crystals with a solution of a regulator in a solvent; and subsequently drying the sucralose crystals to form said crystalline sucralose.
