| titleOfInvention | Method for purifying organic acid |
| abstract | The present invention provides a method for purifying an organic acid, comprising: (a) adding an inorganic flocculant to a fermentation broth containing one organic acid to form a mixture; (b) subjecting the mixture to a centrifugation process to obtain a supernatant a liquid and a precipitate, wherein the organic acid is located in the supernatant; (c) subjecting the supernatant to a membrane extraction procedure to obtain an extract, wherein the membrane extraction procedure comprises: (i) the supernatant The liquid is subjected to an oil phase extraction in an oil phase to form an oil phase extraction product; and (ii) the oil phase extraction product is subjected to a back extraction in a stripping phase to form the extract, wherein during the stripping, the liquid is adjusted a pH of the stripping phase such that at least one carboxyl moiety of the organic acid in the formed extract is in a carboxyl salt state; and (d) subjecting the extract to a crystallization procedure to obtain the organic acid crystallization. |
