| titleOfInvention | Production of citric acid |
| abstract | A process for the recovery of citric acid from a citric acid fermentation broth comprisingn i) subjecting said citric acid fermentation broth to evaporation to produce a concentrate; ii) subjecting such concentrate to an extraction operation with a recycled amine extractant citric acid solution; iii) withdrawing the aqueous extraction raffinate from said extraction operation; iv) withdrawing the said concentrated amine extractant citric acid solution extract and back-extracting it with water to obtain an aqueous citric acid solution and a depleted amine extractant citric acid solution; and v) recycling said depleted amino extractant citric acid solution to the extraction operation. |
