RECOVERY OF STEVIOL GLYCOSIDES

摘要

The present invention relates a process for the recovery of one or more steviol glycosides from a steviol glycoside-containing fermentation broth, which method comprises (a) providing a fermentation broth comprising one or more steviol glycosides and one or more non-steviol glycoside components; (b) separating the liquid phase of the broth from the solid phase of the broth; (c) providing an adsorbent resin; (d) contacting the liquid phase of the broth with the adsorbent resin in order to separate at least a portion of the one or more steviol glycosides from the non-steviol glycoside components, thereby to recover one or more steviol glycosides from the fermentation broth containing one or more steviol glycosides. The invention also relates to a purified steviol glycoside composition prepared using such a process.
