Monosodium-1-glutamate

A seasoning is anything that enhances in flavor or appearance, or gives reflsh to foods. Spices, condiments, and salt or monosodium glutamate (MSG) are all seasonings (see Amino acids (msg)). 

Defatted peanuts are high in protein, low in moisture, contain only 20% of the naturally occurring fat, and have better stability than whole peanuts. Monosodium glutamate (MSG) has been used as a flavor enhancer for defatted nuts, but the result has not been entirely satisfactory as the addition of MSG produces a meaty rather than nutty flavor. This meaty flavor is more compatible with salted butter and nuts than with candy. 

In the food industries a number of amino acids have been widely used as flavor enhancers and flavor modifiers (see Flavors and spices). For example, monosodium L-glutamate is well-known as a meat flavor-enhancer and an enormous quantity of it is now used in various food appHcations (see Amino acids, L-MONOSODIUM glutamate (MSG)). Protein, hydroly2ed by acid or en2yme to be palatable, has been used for a long time in flavoring agents. 

In the case of hyperphenylalaninaemia, which occurs ia phenylketonuria because of a congenital absence of phenylalanine hydroxylase, the observed phenylalanine inhibition of proteia synthesis may result from competition between T.-phenylalanine and L-methionine for methionyl-/RNA. Patients sufferiag from maple symp urine disease, an inborn lack of branched chain oxo acid decarboxylase, are mentally retarded unless the condition is treated early enough. It is possible that the high level of branched-chain amino acids inhibits uptake of L-tryptophan and L-tyrosiae iato the brain. Brain iajury of mice within ten days after thek bkth was reported as a result of hypodermic kijections of monosodium glutamate (MSG) (0.5—4 g/kg). However, the FDA concluded that MSG is a safe kigredient, because mice are bom with underdeveloped brains regardless of MSG kijections (106). 

Molasses is also used as an inexpensive source of carbohydrate in various fermentations for the production lactic acid, citric acid, monosodium glutamate, lysine, and yeast (60). Blackstrap molasses is used for the production of mm and other distilled spirits. 

The aucleotides iaosiae-5 -moaophosphate and guanosiae-5 -monophosphate, produced from yeast RNA are potent flavor potentiators for meat products. They act synergisticaHy with monosodium glutamate and are usually used ia coajuactioa with this amino acid. 

Hydrolyzed soy proteins are also sometimes added to hair-spray. These are more commonly known as soy sauce and MSG (monosodium glutamate), an amino acid.
