Abstract
Disclosed herein is a process where maltol is extracted from a source material containing maltol by employing an aqueous extraction process wherein reverse osmosis is utilized to concentrate an aqueous extract of maltol. The maltol in the concentrated aqueous extract is adsorbed on a bed containing an adsorbent material and then desorbed using a hydrophilic solvent and separated.
