Patent ID: 7354615

Claim:
A process for producing mixed crystals of disodium 5â€²-guanylate and disodium 5 â€²-inosinate, wherein said process comprises precipitating mixed crystals of disodium 5â€²-guanylate and disodium 5â€²-inosinate by simultaneously adding a hydrophilic organic solvent and an aqueous mixed solution of disodium 5â€²-guanylate and disodium 5â€²-inosinate into a crystallization vessel to produce mixed crystals of disodium 5â€²-guanylate and disodium 5â€²-inosinate in a liquid phase, wherein said simultaneously adding is carried out in a manner such that a volumetric concentration of said hydrophilic organic solvent to said liquid phase in said crystallization vessel is maintained in a range of 30-70 vol. %.
