The purification process further involves fractional precipitation of the remaining sugars at a low pressure of ~20 bars. Citric acid and malic acid both precipitate in the same range of pressures, whereas oxalic acid remains behind in the solution as it can be precipitated only under higher pressures of more than 120 bars. This method ...
