Abstract
The present invention relates to a method of separating amino acids from an aqueous solution comprising amino acids as well as proteins and/or protein decomposition products by combining phosphoric acid with the aqueous solution to precipitate an amino acid monophosphate. The precipitate so formed may be separated from the aqueous solution and used as such, e.g. in plant fertilizer compositions. The precipitate may be redissolved in a suitable liquid, after which phosphate and amino acid may be separated following conventional methods. In either case, the present invention enables highly selective precipitation of arginine and/or lysine monophosphate as crystals.
