  • Method for producing ?-glutamyl-valyl-glycine crystal
    Patent number: 9512177
    Abstract: The present invention provides a method for efficiently producing a ?-glutamyl-valyl-glycine crystal. Specifically, the present invention provides a method for producing a ?-glutamyl-valyl-glycine crystal, which includes the steps of: preparing a mixed solution of valyl-glycine or a salt thereof and ?-glutamyl-valyl-glycine, wherein the mixed solution contains valyl-glycine or the salt thereof in an amount of 20 mass % or more relative to the mass of ?-glutamyl-valyl-glycine; adjusting the amount of valyl-glycine or the salt thereof in the prepared mixed solution to 0.1 mass % or more and less than 20 mass % relative to the mass of ?-glutamyl-valyl-glycine to prepare a ?-glutamyl-valyl-glycine solution; and subjecting the ?-glutamyl-valyl-glycine solution to a crystallization procedure to produce the ?-glutamyl-valyl-glycine crystal.
