ABSTRACT:
An improved process for recovering 1-glutamic acid from an aqueous solution containing it by the steps of adjusting the pH of the solution to about 4.5, at ambient temperature, holding at that pH until crystals of 1-glutamic acid begin to appear, heating to from 47.degree. to about 55.degree.C, adjusting the pH to 3.2, cooling, and recovering the crystals resulting therefrom.
