The present invention provides a method for preparing colorless sucralose, wherein 4,1′,6′-trichloro-4,1′,6′-trideoxy-galacto sucrose-6- acetate containing colored impurities formed during chlorination of sucrose-6-acetate is treated with sodium hypochlorite, where sodium hypochlorite acts both as a decolorizing agent and as a reagent for the ester hydrolysis.
