Method of producing basic amino acid or basic amino acid salt

摘要

[Problem] It is to provide a method of producing basic amino acid or basic amino acid salt suitable for each use for medicine, industrial use, feed, food additive and the like, by a simple method to remove HCl from HCl salt of basic amino acid efficiently.;[Solving Means];The above problem is solved by a method of producing a basic amino acid or a basic amino acid salt which comprises allowing to coexist a weak acid in a basic amino acid HCl salt solution, when the solution is dechlorinated using an anion-exchange resin.

1. A method of producing a basic amino acid or a basic amino acid salt which comprises preparing a solution comprising a weak acid and a HCl salt of a basic amino acid to provide a weak acid salt of the basic dechlorinating by passing the solution through an anion-exchange resin to prepare said basic amino acid or basic amino acid salt.
