How is monosodium glutamate made

These microbes consume the glucose, releasing glutamic acid, which though neutralization is turned into a solution. This solution is then decolorized and filtered for purity.

The entire process has a very small environmental footprint, as its coproducts can be returned to the soil in the form of fertilizer to help grow more crops like sugarcane, forming a virtuous cycle.

This pure solution is crystallized using an evaporator and the crystals dried to produce the final product—MSG.

Simple table salt, sodium chloride, is one of the biggest contributors to cardiovascular disease. The use of monosodium glutamate MSG can be the key to reducing sodium content without sacrificing taste. 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.

Sodium reduction in butter, margarine and cheeses can also be achieved with MSG, and a similar approach could work in meat products. The use of MSG may help food scientists reduce sodium content without sacrificing taste, in addition to creating new, cost-effective, reduced-salt products and menus that will encourage consumers to make healthier choices. The Ajinomoto Group initiatives to reduce salt intake with umami. What is MSG and how is it made?

Our bodies ultimately metabolize both sources of glutamate in the same way. An average adult consumes approximately 13 grams of glutamate each day from the protein in food, while intake of added MSG is estimates at around 0.

FDA requires that foods containing added MSG list it in the ingredient panel on the packaging as monosodium glutamate. However, MSG occurs naturally in ingredients such as hydrolyzed vegetable protein, autolyzed yeast, hydrolyzed yeast, yeast extract, soy extracts, and protein isolate, as well as in tomatoes and cheeses.

While FDA requires that these products be listed on the ingredient panel, the agency does not require the label to also specify that they naturally contain MSG. MSG enhances the savory, meaty umami flavor of foods. Umami is the fifth basic taste, along with salty, sour, bitter and sweet 2.

The average daily intake of MSG is 0. MSG is the sodium salt of glutamic acid, an amino acid found in your body and most foods. It is a popular food additive because it enhances flavor. Glutamic acid functions as a neurotransmitter in your brain. It is an excitatory neurotransmitter, meaning that it stimulates nerve cells in order to relay its signal.

Some people claim that MSG leads to excessive glutamate in the brain and excessive stimulation of nerve cells. Fear of MSG dates as far back as , when a study found that injecting large doses of MSG into newborn mice caused harmful neurological effects 4. However, dietary glutamate should have little to no effect on your brain, as it cannot cross the blood-brain barrier in large amounts 6.

Overall, there is no compelling evidence that MSG acts as an excitotoxin when consumed in normal amounts. While some people assert that the glutamate from MSG can act as an excitotoxin, leading to the destruction of nerve cells, no human studies support this.

Symptoms included headache , muscle tightness, numbness, tingling, weakness and flushing. The threshold dose that causes symptoms seems to be around 3 grams per meal. However, keep in mind that 3 grams is a very high dose — about six times the average daily intake in the US 1 , 3. It is unclear why this happens, but some researchers speculate that such large doses of MSG enable trace amounts of glutamic acid to cross the blood-brain barrier and interact with neurons, leading to brain swelling and injury 8.

However, other similar studies did not find any relationship between MSG intake and asthma 10 , 11 , 12 ,
