Process of preparing an organic acid |
摘要 |
Method for the recovery of an organic acid (I) and/or its salt from a solution obtained by fermentation, using a pure carbohydrate as raw material for the substrate production. The solution is freed from cells, then protein in the permeate is precipitated by adding a siliceous precipitant at 2-70 degrees C and protein is separated. Finally, the permeate is concentrated and crystallised in ≥ 1 stage. |
