Abstract
A process for the purification of aqueous feed streams containing sucralose and/or sucralose 6-esters includes, providing an aqueous feed stream including the sucralose and/or sucralose 6-esters, concentrating the aqueous feed stream to form a concentrated aqueous feed stream containing at least 10 wt % total carbohydrates and extracting the concentrated aqueous feed stream with an organic solvent and producing an organic extract and an aqueous extract, in which the organic solvent is immiscible with water, and in which the carbohydrate preferentially passes into the organic extract.
