Abstract
The common precipitation process for the isolation of citric acid produces 2,5 tons of waste per ton citric acid. This paper presents a way to separate citric acid from a fermentation broth by avoiding the waste production of CaSO4. A combination of an extraction/reextraction process using a tertiary‐amine‐containing solvent was developed.Keywords
