Monosodium glutamate (monosodium L-glutamate or monosodium glutamate) is found naturally in tomatoes, cheese, mushrooms, and other foods. Monosodium glutamate is about 78 percent monosodium and 21 percent glutamate. The addition of it to food is through food processing. It is approved for use as a flavoring by the FDA and is Generally Recognized As Safe (GRAS). It was discovered by Japanese chemist Kikunae Ikeda who isolated it from seaweed in 1908. It wasn’t until the 1950s that it started being widely used as a flavor enhancer through food manufacturing.
What is monosodium glutamate?
Monosodium glutamate definition
Monosodium glutamate (MSG) is the sodium salt of glutamic acid, one of the most abundant naturally occurring non-essential amino acids. Glutamic acid is commonly found in tomatoes and other foods, where it contributes to their savory taste. Glutamate is an important neurotransmitter in the brain.
The Food and Drug Administration (FDA) has classified MSG as “generally recognized as safe” (GRAS). The European Union classifies it as a food additive permitted in certain foods and subject to quantitative limitations.
MSG has the HS code 29224220 and ADR/RID code 3A2D.
Monosodium glutamate common name
Monosodium glutamate is a flavor enhancer found in many processed foods. It’s also known as MSG, E621 and 621.
Monosodium glutamate formula
The chemical formula of monosodium glutamate is C5H8NaNO4 · H2O.
What is monosodium glutamate used for in food?
Monosodium glutamate uses in many food.
Monosodium glutamate (MSG) is a flavor enhancer that has been used for decades. A lot of people have heard about MSG and think of it as an unhealthy additive, but this isn’t true.
MSG is naturally occurring in many foods including mushrooms, tomatoes and cheese. It is also found in some vegetables like soybeans and wheat.
The FDA considers MSG to be safe for consumption by healthy individuals at any age. However, people with severe food allergies may need to avoid it completely.
Monosodium glutamate foods
MSG is often added to foods to enhance the flavor and make them taste more savory. It can be used in canned soups and canned vegetables to give them a more natural taste than they would otherwise have when they are cooked on their own. It has also been used to enhance the flavor of frozen dinners since they don’t contain much actual meat or other ingredients that add their own flavors to the dish. If you want to make your own frozen meals at home, adding a small amount of MSG can improve the overall taste while keeping costs down because you won’t have to buy all of those expensive ingredients separately just so that your food will taste better

What is monosodium glutamate made from?
Monosodium glutamate, or MSG, is a food additive that’s used to enhance the flavor of foods. It’s also known as glutamate or glutamic acid.
MSG is made by fermenting starch, sugar beets or molasses with a bacterium called “Amino Acids” and then isolating the amino acids from the solution. The amino acids are then processed into MSG to create a white crystalline powder that’s about 80% protein by weight.
How is monosodium glutamate made?
During production, it undergoes a natural fermentation process, followed by neutralization and crystallization.
These four authority resources mention the manufacturing process, respectively from Wikipedia, EFSA, a Chinese big manufacturer, and Ajinomoto.
Let’s look at them one by one.
The majority of MSG is produced industrially by fermenting starches and sugars, such as corn starch and tapioca starch. Instead of being extracted and crystallized from seaweed, this was done by Japanese scientists in 1908.
For the fermentation of L-glutamic acid, there are two bacteria approved; one is Corynebacterium glutamicum strain 2256 and another is a genetically modified strain of C. glutamicum (the strain EA-12).
In both processes, glutamic acid is produced via fed-batch fermentation utilizing carbon sources from vegetal origin (sucrose), nitrogen sources, salts, vitamins.
3. A China Big Manufacturer
Using corynebacterium glutamicum to produce glutamic acid from glucose fermentation, and then neutralizing it with sodium carbonate. In the following steps, decolorization, filtration, crystallization, centrifugation, and drying are carried out.
AJINOmoto says their brand MSG AJI-NO-MOTO® is manufactured in Brazil from sugarcane molasses fermentation and has provided a flow chart for this process.
|Appearance||A white, practically odorless crystalline granular or powder.|
|CAS number||6106-04-03 (monohydrate)|
|Melting Point||232 °C (450 °F; 505 K)|
|Stability||Stable in high temperatures and in the presence of light. Around 0.6% of MSG will decompose when heated its 10% solution in 100ºC for 3 hours in PH 6.9. It will lose the combined crystallization water when heated to 120ºC.|
Is only chinese food with monosodium glutamate?
There are many people who believe that the only Chinese food that contains MSG is Chinese takeout. This is not true.
Most people don’t realize that MSG is a natural component of many foods, and it’s added to others. It’s even found in some foods that you’d never think would contain it.
Monosodium glutamate is a flavor enhancer that is used in many different types of cuisines around the world. It’s found naturally in tomatoes, cheeses and meats. But it can also be added to other foods for flavor enhancement purposes as well.
MSG is also known as:
- Ajinomoto (the scientific name)
- MSG (the common name)
Is monosodium glutamate safe to eat?
Ingredients approved by the FDA (U.S. Food and Drug Administration) and EFSA (European Food Safety Authority) as acceptable food additives are safe for human consumption.
A FDA review found that MSG additions to foods are “generally recognized as safe” (GRAS). FDA classified it as one of “Special Dietary and Nutritional Additives” along with amino acids and claimed that it is a direct food additive and may be used in foods as nutrients.
A food additive called monosodium glutamate (E621) is regulated in the European Union (EU) under Annex II of Regulation (EC) No 1333/2008 as a “food additive other than colors and sweeteners.”
Re-evaluation In 2017
The studies on genotoxicity, carcinogenicity, neurotoxicity, and reproductive and developmental toxicity did not demonstrate adverse effects.
The EFSA published a group acceptable daily intake (ADI) estimate of glutamic acid at 30 mg/kg body weight per day in June 2017.
In addition, the EFSA identified the ADI related to the MSG symptom complex (> 42.9 mg/kg), headache (85.8 mg/kg), blood pressure increase (150 mg/kg), and insulin increase (> 143 mg/kg).

What are the benefits of monosodium glutamate in food?
1. Taste enhancement
The first and most obvious benefit of monosodium glutamate is taste enhancement. Monosodium glutamate is a flavor enhancer that makes food taste better by enhancing the flavors already present in the food. This can be done by adding extra flavor to bland foods or by making strong flavors more palatable for people who cannot eat large amounts of spice or other strong flavors due to allergies or intolerances.
2. Helps low salt diets
Monosodium glutamate can also be used on low sodium diets as well as high sodium diets because it does not contain any sodium at all. Many people are trying to reduce their sodium intake due to health concerns such as high blood pressure and heart disease, so choosing foods with no added salt can be difficult without monosodium glutamate as an option for flavor enhancement.
3. Reduces hunger pangs
Monosodium glutamate has been shown to reduce hunger pangs in people who are overweight or obese as well as those who are trying to lose weight through dieting or exercise programs. This means that if you eat something with MSG in it before bedtime, you will experience less hunger during the night which means fewer cravings for unhealthy snacks late at night!
What are the possible side effects of monosodium glutamate?
Mononosodium Glutamate (MSG) is a well-known and controversial ingredient. It is not uncommon for consumers to wonder whether MSG is bad for their health and what the side effects are. Though the FDA and EFSA have approved its safety for years, it frequently receives public safety attention.
Why is monosodium glutamate controversial?
The usage of this drug remains controversial for some people since it poses a lot of health risks for those who are intolerant to it. There are several common risks, including headaches, brain damage, neurotoxins, high blood pressure, Chinese Restaurant Syndrome, etc.
Some consumers avoid MSG in favor of its replacement because they believe it has ill effects on health. It is understandable that consumers are concerned about the ingredients in their food.
Let’s begin with the metabolism, then move on to its possible side effects.
What are monosodium glutamate allergies?
Monosodium glutamate (MSG) is a common ingredient in many foods, including salad dressing and canned vegetables.
