Why is monosodium glutamate not hydrolyzed?
Monosodium glutamate is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions (1). Monosodium glutamate does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight (1).
How does monosodium glutamate release into the atmosphere?
If released to air, monosodium glutamate will exist solely in the particulate phase in the atmosphere since it is a salt. Particulate-phase monosodium glutamate will be removed from the atmosphere by wet or dry deposition. Monosodium glutamate does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight. If released to soil, monosodium glutamate is expected to have very high mobility based upon an estimated Koc of 4. Volatilization from soil and water surfaces will not occur since monosodium glutamate is a salt. Several genera of bacteria have been shown to possess enzymatic capability to degrade l-glutamic acid and monosodium glutamate was readily degraded in sediment/ water microcosms using both seawater and estuarine water. If released into water, monosodium glutamate is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. An estimated BCF of 1 suggests the potential for bioconcentration in aquatic organisms is low.

How is glutamate absorbed?
Glutamate is absorbed from the gut by an active transport system specific for amino acids. This process is saturable, can be competitively inhibited, and is dependent on sodium ion concentration... . During intestinal absorption, a large proportion of glutamic acid is transaminated and consequently alanine levels in portal blood are elevated. If large amounts of glutamate are ingested, portal glutamate levels increase ... . This elevation results in increased hepatic metabolism of glutamate, leading to release of glucose, lactate, glutamine, and other amino acids, into systemic circulation ... . The pharmacokinetics of glutamate depend on whether it is free or incorporated into protein, and on the presence of other food components. Digestion of protein in the intestinal lumen and at the brush border produces a mixture of small peptides and amino acids; di-and tri-peptides may enter the absorptive cells where intracellular hydrolysis may occur, liberating further amino acids. Defects are known in both amino acid and peptide transport ... .. Glutamic acid in dietary protein, together with endogenous protein secreted into the gut, is digested to free amino acids and small peptides, both of which are absorbed into mucosal cells where peptides are hydrolyzed to free amino acids and some of the glutamate is metabolized. Excess glutamate and other amino acids appear in portal blood. As a consequence of the rapid metabolism of glutamate in intestinal mucosal cells and in the liver, systemic plasma levels are low, even after ingestion of large amounts of dietary protein. / Glutamic acid /

What is MSG made of?
Today, the MSG (monosodium glutamate) produced by the Ajinomoto Group is produced through fermentation of plant-based ingredients such as sugar cane, sugar beets, cassava or corn. MSG is the sodium salt of glutamic acid, one of the most common naturally occurring amino acids. Glutamic acid is produced in abundance in our bodies and found in many foods we eat every day, including meat, fish, eggs and dairy products, as well as tomatoes, corn and nuts. When a protein containing glutamic acid is broken down, for example through fermentation, it becomes glutamate. Glutamate activates our taste receptors, eliciting the delicious savory taste known as umami.
What is MSG?
A popular seasoning and flavor enhancer, MSG, or monosodium glutamate, is the purest form of umami, the fifth taste. MSG (monosodium glutamate) is widely used to intensify and enhance umami flavors in sauces, broths, soups and many more foods. It can also be used as a partial replacement for salt, containing just one-third the sodium, and is classed as safe by the United States Food and Drug Administration and the World Health Organization. Originally associated mainly with Asian cuisines, MSG (monosodium glutamate) is now used around the world to bring out the delicious flavor of foods.
How did MSG get its start?
At first it was produced through the hydrolysis of gluten to extract wheat protein. Then in the 1930s there was a shift to extracting MSG from soy beans. In the 1960s production moved to the bacterial fermentation of sugar cane and similar crops in a process much like the way cheese, yogurt and wine are produced.
What is the name of the Japanese word for umami?
Tasting the crystals, he recognized a distinct savory flavor he dubbed umami, based on the Japanese word umai (delicious).

Is MSG high in sodium?
Taste is a major driver of excess salt intake. Although MSG is mistakenly thought of as being high in sodium, it contains just one third the sodium of table salt (MSG contains approximately 12 percent sodium while table salt contains 39 percent sodium) It can enhance the perception of saltiness while preserving palatability. With the addition of MSG, sodium level in the food can be lowered by up to 40 percent while maintaining the flavor.
Overview
Monosodium glutamate (MSG), also known as sodium glutamate, is the sodium salt of glutamic acid. MSG is found naturally in some foods including tomatoes and cheese in this glutamic acid form. MSG is used in cooking 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.
Use
Pure MSG is reported to not have a highly pleasant taste until it is combined with a savory aroma. The basic sensory function of MSG is attributed to its ability to enhance savory taste-active compounds when added in the proper concentration. The optimal concentration varies by food; in clear soup, the "pleasure score" rapidly falls with the addition of more than one gram of MSG per 100 mL.
Safety
MSG is generally recognized as safe to eat. A popular belief is that MSG can cause headaches and other feelings of discomfort, but blinded tests have found no good evidence to support this. International bodies governing food additives currently consider MSG safe for human consumption as a flavor enhancer. Under normal conditions, humans can metabolize relatively large quantities of glutamate, which is naturally produced in the gut in the course of protein hydr…
Production

History
Glutamic acid was discovered and identified in 1866 by the German chemist Karl Heinrich Ritthausen, who treated wheat gluten (for which it was named) with sulfuric acid. Kikunae Ikeda of Tokyo Imperial University isolated glutamic acid as a taste substance in 1908 from the seaweed Laminaria japonica (kombu) by aqueous extraction and crystallization, calling its taste umami ("pleasant savory taste"). Ikeda noticed that dashi, the Japanese broth of katsuobushi and kombu, …
Society and culture
MSG is one of several forms of glutamic acid found in foods, in large part because glutamic acid (an amino acid) is pervasive in nature. Glutamic acid and its salts may be present in a variety of other additives, including hydrolyzed vegetable protein, autolyzed yeast, hydrolyzed yeast, yeast extract, soy extracts, and protein isolate, which must be specifically labeled. Since 1998, MSG cannot be included in the term "spices and flavorings". However, the term "natural flavor" is used …
