Abstract
Disclosed is a continuous process for the purification of steviol glycosides such as Rebaudioside D and/or Rebaudioside M extracted from the dried stevia leaves or extracted from a fermentation broth using continuous simulated moving bed processes and nanofiltration without the addition of organic solvents to obtain a purified steviol product comprising sweet steviol glycosides. The sweet steviol glycosides can be used as substitutes for caloric sweeteners in beverages and in other food items.
