How is MSG made?

MSG has been produced by three methods: hydrolysis of vegetable proteins with hydrochloric acid to disrupt peptide bonds (1909–1962); direct chemical synthesis with acrylonitrile (1962–1973), and bacterial fermentation (the current method). Wheat gluten was originally used for hydrolysis because it contains more than 30 g of glutamate and glutamine in 100 g of protein. As demand for MSG increased, chemical synthesis and fermentation were studied. The polyacrylic fiber industry began in Japan during the mid-1950s, and acrylonitrile was adopted as a base material to synthesize MSG.

NIOSH (NOES Survey 1981-1983) has statistically estimated that 60,341 workers (22,829 of these are female) are potentially exposed to monosodium glutamate in the US (1). Occupational exposure to monosodium glutamate may occur through dermal contact with this compound at workplaces where monosodium glutamate is produced or used (SRC). The general population is exposed to monosodium glutamate primarily via ingestion of food products containing this additive (SRC).

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. Occupational exposure to monosodium glutamate may occur through dermal contact with this compound at workplaces where monosodium glutamate is produced or used. The general population is exposed to monosodium glutamate primarily via ingestion of food products containing this additive. (SRC)

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).

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 /

How is glutamic acid metabolized?

Glutamic acid is metabolized in the tissues by oxidative deamination ... or by transamination with pyruvate to yield oxaloacetic acid ... which, via alpha-ketoglutarate, enters the citric acid cycle ... .. Quantitatively minor but physiologically important pathways of glutamate metabolism involve decarboxylation to gamma-aminobutyrate ( GABA) and amidation to glutamine ... . Decarboxylation to GABA is dependent on pyridoxal phosphate, a coenzyme of glutamic acid decarboxylase ..., as is glutamate transaminase. Vitamin B6 -deficient rats have elevated serum glutamate levels and delayed glutamate clearance ... . / Glutamic acid /
