| titleOfInvention | Manufacturing process of purified lactic acid |
| abstract | An object of the present invention is to provide a manufacturing process of purified lactic acid which is a process of concentrating a lactic acid fermentation liquid at a low temperature. A manufacturing process of purified lactic acid comprising a fermentation process where a pH adjusting agent containing calcium and a microorganism are added to a sugar-containing solution to produce lactic acid in the form of calcium lactate, and a purification process where sulfuric acid is added to a solution containing calcium lactate to separate calcium ions in the form of calcium sulfate, wherein the process further comprises, prior to the step of adding sulfuric acid, a reverse osmosis membrane concentration step (140) where the solution containing calcium lactate is allowed to pass through a reverse osmosis membrane to remove water; a crystallization step (150) where the obtained concentrated liquid of calcium lactate is cooled to crystallize and remove calcium lactate; and a reverse osmosis membrane concentration step (140) where the solution from which calcium lactate has been removed is heated and allowed to pass through the reverse osmosis membrane (141a - 141c) to remove water, the crystallization step (150) and the subsequent reverse osmosis membrane concentration step (140) being repeated one or more times. |
