FIELD: chemistry.
SUBSTANCE: invention concerns a variant of admixture extraction from composition containing extraneous matter and sucralose, which is used as a sweetener. One of the variants includes following stages: (a) first solvent extraction of the said composition containing sucralose and admixtures in the first solvent with the help of another solvent, at least partially immiscible, in order to remove admixtures to the said second solvent; (b) second solvent extraction of the said composition containing sucralose and admixtures in the first solvent with the help of the third solvent, at least partially immiscible, in order to transfer sucralose to the said third solvent; where stage (a) removes at least a part of admixtures to the second solvent; and stage (b) transports most of sucralose to the third solvent and detains most of admixtures in the first solvent.
EFFECT: efficient removal of admixtures from compositions.
