Abstract

The invention discloses a glutamic acid separating and extracting technology. The technology is characterized in that glutamic acid in the isoelectric point liquid of glutamic acid is separated and extracted through adopting an ion exchange method, an acid solution not an alkali solution is directly used to elute for generation after the ion exchange resin adsorption of the glutamic acid, and an eluate obtained after the ion exchange returns to an isoelectric operation for glutamic acid extraction. Compared with traditional technologies, the technology disclosed in the invention has the advantages of saving of a large amount of an acid and an alkali, reduction of the production cost and the environmental pollution, and economic benefit improvement.

Description

technical field [0001] The invention belongs to the technical field of amino acid production, and in particular relates to a separation and extraction process of glutamic acid. Background technique Glutamic acid is an acidic amino acid. The molecule contains two carboxyl groups, and its chemical name is α-aminoglutaric acid. Glutamic acid was discovered by Li Suxun in 1856. It is a colorless crystal with umami taste, slightly soluble in water, but soluble in hydrochloric acid solution, with an isoelectric point of 3.22. A large amount exists in cereal protein, and the content in animal brain is also more. Glutamic acid plays an important role in the protein metabolism process in organisms, and participates in many important chemical reactions in animals, plants and microorganisms. Sodium glutamate, commonly known as monosodium glutamate, is an important umami agent that enhances the fragrance. Sodium glutamate is widely used as a food flavoring agent, either alone or i...
