Usage

Uses

Used in Food Industry:
Monosodium glutamate is used as a flavor enhancer for its ability to intensify and enhance the flavor of foods. It is used at 0.1–1.0% in meats, soups, and sauces, and is particularly popular in Chinese cuisine.
Used in Agricultural Feed Supplements:
A small portion of MSG is used as an agricultural feed supplement, specifically for swine, to improve the taste and nutritional value of their feed.
Used in Pesticides and Pharmaceuticals:
Although a minor application, MSG is also used in the production of pesticides and pharmaceuticals due to its unique properties.

History

The use of Monosodium glutamate(MSG) as a flavor enhancer is attributed to Kikunae Ikeda (1864 1936), a chemistry professor from Tokyo Imperial University. Ikeda patented Monosodium glutamate(MSG) as a flavor enhancer along with processes used to produce it. The isolated glutamic acid was then purified and converted to MSG. The use of Monosodium glutamate(MSG) as a flavor enhancer began in Japan and Asia, but widespread use of the compound in the United States did not occur until after World War II. Ajinomoto started manufacturing Monosodium glutamate(MSG) in the United States in 1956 (Ajinomoto became affiliated with Kraft General Foods in 1973).

CATALYTIC POTENCY OF FUNCTIONALIZED (2,5)PYRIDINOPHANES AS NEW PYRIDOXAL MODEL COMPOUNDS

Catalytic activities of new model compounds, 1a-c, 2, and 3, for the racemization of monosodium L-glutamate were shown to be more potent, ca. 1.5 fold, than that of pyridoxal, and catalyst, 1a, was stable enough to show no decomposition throughout the reaction.

CAGED COMPOUND, AND MANUFACTURING METHOD AND EXPRESSION METHOD OF CAGED COMPOUND

PROBLEM TO BE SOLVED: To provide a caged compound excellent in light reactivity and dark place stability, and capable of deprotection by a visible light. SOLUTION: A caged compound is represented by the following general formula (1). In the general formula (1), R1 represents a hydrogen atom, a halogen atom, an alkyl group, an aryl group, a cyano group, an alkoxy group, a hydroxy group, or an alkylamino group, R2 represents an alkyl group or a hetero atom other than a nitrogen atom, R3 represents a hydrogen atom, a halogen atom or an alkyl group, X represents a monovalent anion, Y represents a monovalent organic group, Z represents a hydrogen atom or a monovalent organic group, and a represents 0 or 1, however a represents 0 when R2 represents the hetero atom other than the nitrogen atom.

Silicon nanowire photocathodes for light-driven electroenzymatic synthesis

The photoelectroenzymatic synthesis of chemical compounds employing platinum nanoparticle-decorated silicon nanowires (Pt-SiNWs) is presented. The Pt-SiNWs proved to be an efficient material for photoelectrochemical cofactor regeneration because the silicon nanowires absorbs a wide range of the solar spectrum while the platinum nanoparticle serve as an excellent catalyst for electron and proton transfer. By integrating the platform with redox enzymatic reaction, visible-light-driven electroenzymatic synthesis of L-glutamate was achieved. Compared to electrochemical and photochemical methods, this approach is free from side reactions caused by sacrificial electron donors and has the advantage of applying low potential to realize energy-efficient and sustainable synthesis of chemicals by a photoelectroenzymatic system.
