text: In the process of the present invention the crude glutamic acid is slurred in fresh water or wash water from subsequent steps in the purification process and is dissolved therein while maintaining the solution at a pH of between about 0.4 and about 0.8, preferably about 0.6 and at this pH while the glutamic acid remains in solution either as such or as the hydrochloride (where hydrochloric acid is employed as the acidifying agent) the organic colloidal impurities (whose exact chemical character is so far unknown) remain in suspension and tend to coagulate and fiocculate into a readily filtrable form, the precipitate being also easily washed and freed of mother liquor.
