Abstract A process for the precipitation of one or more amino and/or organic acids from a liquid feed comprising a plurality of amino and/or organic acids, comprising providing, in a precipitation vessel, a solution of amino and/or organic acids from the feed in a mixture of a solvent and an anti-solvent; passing the mixture through a zone capable of selectively removing solvent and/or adding anti-solvent from an external source to the mixture, to provide a mixture depleted in solvent and enriched in anti-solvent, thereby increasing the concentration of the amino and/or organic acids in the solvent/anti-solvent mixture, allowing solid particles of the amino and/or organic acids to precipitate from the solvent/anti-solvent mixture in the precipitation vessel at a precipitation temperature; and discharging precipitated solid particles of the amino and/or organic acids from the precipitation vessel.
