Abstract
Glutamic acid is obtained from vinasse by heating the vinasse with an alkaline earth oxide or hydroxide for such a time that no appreciable hydrolysis of the pyrrolidone carboxylic acid occurs, separating solid matter from the liquid, hydrolysing the pyrrolidone carboxylic acid in the solution in known manner, and isolating glutamic acid by adjustment of the pH of the solution to approximately that of the isoelectric point of glutamic acid. If concentrated vinasse is used as starting material, it should be diluted, preferably with 1-3 times its weight of water. The preferred quantity of alkaline earth compound is 2-20 per cent by weight of hydroxide, or an equivalent amount of oxide, referred to concentrated vinasse. The heating time is brief, generally about 10 minutes at 50-100 DEG C. Specification 817,178 is referred to.
