Abstract
This invention relates to processes for purifying sucralose by the use of an initial non-crystallization purification procedure followed by three or more sequential crystallization steps and recycle of the mother liquor remaining from each crystallization step to the feed of another crystallization or purification step. This invention also relates to sucralose compositions as well as compositions comprising the sucralose compositions of the present invention. These compositions may be highly pure and have a superior taste profile.
