Process for the Production of L-Citrulline

摘要

Processes for producing a suitable purity grade of L-Citrulline are disclosed. The processes can include contacting crude L-Citrulline in an aqueous solution with an adsorptive medium at a temperature above approximately 50° C. and below the temperature of denaturement for the L-Citrulline for an interval sufficient to remove at least one contaminant from the L-Citrulline. The processes can also include concentrating the dissolved L-Citrulline relative to the aqueous solution.
