Crystallization of steviol glycosides

A method for purifying rebaudioside M, which method comprises:

• (a) providing a solution comprising rebaudioside M, wherein the solution is a fermentation broth which has undergone a solid-liquid separation to separate cells from the fermentation broth, wherein the rebaudioside M in the solution has a concentration of at least about 10 g/L and a purity of at least 10% by weight on a dry basis;
• and
• (b) crystallizing rebaudioside M from the solution of (a) wherein the crystallizing is carried out in water and in the absence of organic solvent, thereby obtaining purified rebaudioside M,
• wherein the method is performed without chromatography, and in the absence of organic solvent.
