Tien Chu Ve-Tsin Chemical Limited is a Chinese manufacturer of honey by-products, food chemicals and additives including monosodium glutamate or MSG.
Monosodium glutamate (MSG), also known as sodium glutamate, is the sodium salt of glutamic acid, one of the most abundant naturally occurring non-essential amino acids. Glutamic acid is found naturally in tomatoes, grapes, cheese, mushrooms and other foods. MSG is used in the food industry as a flavor enhancer with an umami taste that intensifies the meaty, savory flavor of food, as naturally occurring glutamate does in foods such as stews and meat soups.
Founded in Shanghai in 1923, the firm also had operations in Hong Kong. Wu Zhifan became CEO of Tien Chu Ve-Tsin.
Shanghai is one of the four municipalities under the direct administration of the central government of the People's Republic of China, the most populous urban area in China, and the second most populous city proper in the world, with a population of 26.3 million as of 2019.

Rival and larger MSG maker is Ajinomoto of Japan.
Glutamate flavoring is a generic name for the flavor-enhancing compounds based on glutamic acid and its salts (glutamates). These compounds provide an umami (savory) taste to food.
Kikunae Ikeda was a Japanese chemist and Tokyo Imperial University professor of Chemistry who, in 1908, uncovered the chemical basis of a taste he named umami. It is one of the five basic tastes along with sweet, bitter, sour and salty.
Umami or savory taste is one of the five basic tastes. It has been described as savory and is characteristic of broths and cooked meats.
Glutamic acid is an α-amino acid that is used by almost all living beings in the biosynthesis of proteins. It is non-essential in humans, meaning the body can synthesize it. It is also an excitatory neurotransmitter, in fact the most abundant one, in the vertebrate nervous system. It serves as the precursor for the synthesis of the inhibitory gamma-aminobutyric acid (GABA) in GABA-ergic neurons.
Adenosine monophosphate (AMP), also known as 5'-adenylic acid, is a nucleotide. AMP consists of a phosphate group, the sugar ribose, and the nucleobase adenine; it is an ester of phosphoric acid and the nucleoside adenosine. As a substituent it takes the form of the prefix adenylyl-.
Disodium inosinate (E631) is the disodium salt of inosinic acid with the chemical formula C10H11N4Na2O8P. It is used as a food additive and often found in instant noodles, potato chips, and a variety of other snacks. Although it can be obtained from bacterial fermentation of sugars, it is often commercially prepared.
Amoy Food Limited is a cooking sauce and manufacturer of condiments in Hong Kong. Its products, which now include foodstuffs such as frozen foods and instant foods for heating in a microwave oven, are sold around the world. It is owned by CITIC Capital, a subsidiary of the CITIC Group.
Disodium guanylate, also known as sodium 5'-guanylate and disodium 5'-guanylate, is a natural sodium salt of the flavor enhancing nucleotide guanosine monophosphate (GMP). Disodium guanylate is a food additive with the E number E627. It is commonly used in conjunction with glutamic acid.
Ajinomoto Co., Inc. is a Japanese food and biotechnology corporation which produces seasonings, cooking oils, frozen foods, beverage, sweeteners, amino acids, and pharmaceuticals. AJI-NO-MOTO is the trade name for the company's original monosodium glutamate (MSG) product. The corporation's head office is located in Chūō, Tokyo.

Guanosine monophosphate (GMP), also known as 5'-guanidylic acid or guanylic acid, is a nucleotide that is used as a monomer in RNA. It is an ester of phosphoric acid with the nucleoside guanosine. GMP consists of the phosphate group, the pentose sugar ribose, and the nucleobase guanine; hence it is a ribonucleoside monophosphate. Guanosine monophosphate is commercially produced by microbial fermentation. It is known as E number reference E626.
Inosinic acid or inosine monophosphate (IMP) is a nucleoside monophosphate. Widely used as a flavor enhancer, it is typically obtained from chicken byproducts or other meat industry waste. Inosinic acid is important in metabolism. It is the ribonucleotide of hypoxanthine and the first nucleotide formed during the synthesis of purine. It is formed by the deamination of adenosine monophosphate, and is hydrolysed to inosine. IMP is an intermediate ribonucleoside monophosphate in purine metabolism. The enzyme deoxyribonucleoside triphosphate pyrophosphohydrolase, encoded by YJR069C in Saccharomyces cerevisiae and containing (d)ITPase and (d)XTPase activities, hydrolyzes inosine triphosphate (ITP) releasing pyrophosphate and IMP.
