ABSTRACT:
A water-immiscible organic extractant system can economically be used to recover citric acid from molasses fermenter beer containing a high salt content by using a process combination of passing the aqueous raffinate from the citric acid extraction step through a basic anion-exchange resin to adsorb residual citric acid and release citrate anions from previously formed salt cation-citrate compounds. Trisodium citrate is then eluted from the resin by passing aqueous sodium hydroxide therethrough.
