Abstract:
A process for separating glycyrrhizic acid from licorice extract feed includes the steps of: providing a licorice extract feed and passing the licorice extract feed through an ultrafiltration device to produce a concentrate and a permeate. The ultrafiltration device contains a membrane that is selected to separate the glycyrrhizic acid from other components of the feed such that at least a substantial percentage of the glycyrrhizic acid is retained in the concentrate.
