L-ORNITHINE-CITRIC ACID SALT CRYSTAL

摘要

The present invention provides a crystal of a salt of L-ornithine and citric acid, the crystal of the salt of L-ornithine and citric acid in which pH of the 5 weight % aqueous solution is 3 to 6, the crystal of the salt of L-ornithine and citric acid in which a composition ratio of L-ornithine and citric acid is 2: 1 (molar ratio), a process for producing the crystals of the salt of L-ornithine and citric acid which comprises dissolving L-ornithine and citric acid in water, and precipitating the crystal from the resulting aqueous solution, the process for producing the crystal of the salt of L-ornithine and citric acid in which the pH of the aqueous solution is 3 to 6, and the like.
