A PROCESS FOR THE PREPARATION OF MONOSODIUM GLUTAMATE |
摘要 |
The invention provides a process for the preparation of monosodium glutamate from a fermentatively-prepared solution containing monoammonium glutamate, the process comprising: a) contacting the solution containing monoammonium glutamate salt with a basic anion exchange resin of at least medium strength to split the salt, whereby glutamate anions attach to the anion exchanger and ammonia is released in the solution; b) subjecting the ammonia-containing solution to distillation, to recover volatile ammonia therefrom; c) contacting the glutamate-containing anion exchange resin with a sodium base solution to regenerate the basic anion exchanger and to directly form monosodium glutamate salt in solution; and d) crystallizing monosodium glutamate salt directly from the monosodium glutamate-containing solution, wherein the crystallized salt has a purity of at least 98 %.
