Monosodium glutamate (MSG) is a flavour enhancer commonly used in Asian cooking. It is derived from glutamic acid, which occurs naturally in many foods, including seaweed, tomatoes, poultry, cheese, and milk. MSG was first extracted in 1908 and has since been used as a seasoning, especially in Asian cuisine. Despite its popularity, MSG has also been the subject of controversy, with some people experiencing adverse reactions and reporting symptoms like headaches, nausea, and heart palpitations. While it is deemed safe by Food Standards Australia, it is important to note that excessive consumption may lead to high blood pressure. In Australia, MSG is not banned, but it must be labelled in packaged foods, providing consumers with the choice to avoid it if they so desire.

Monosodium glutamate (MSG) is a legal food additive in Australia
Monosodium glutamate (MSG), also known as sodium glutamate, is a legal food additive in Australia. It is commonly found in many Asian sauces, stock cubes, and snacks. MSG is the sodium salt of glutamic acid, which is found naturally in foods such as tomatoes, cheese, seaweed, poultry, and milk.
MSG was first prepared in 1908 by Japanese biochemist Kikunae Ikeda, who isolated glutamic acid from seaweed and noted its unique savoury taste, which he called "umami". Ikeda submitted a patent for his product, and commercial production of MSG began in 1909. Today, MSG is mass-produced from fermented cornstarch, sugar cane, molasses, or beet and is used as a flavour enhancer in various processed foods.
In Australia, MSG is deemed safe for consumption by Food Standards Australia New Zealand (FSANZ). FSANZ states that while some people may experience mild hypersensitivity reactions to large amounts of MSG consumed in a single meal, these reactions are not allergies or intolerances but sensitivities. These reactions are known as MSG symptom complex and include various adverse effects. However, blinded tests have not provided strong evidence that MSG is the direct cause of these symptoms.
Standard 1.2.4 of the Australia and New Zealand Food Standards Code requires MSG to be labelled in packaged foods. The label must include the food-additive class name, such as "flavour enhancer", followed by "MSG" or its International Numbering System (INS) number, 621. This labelling requirement allows consumers who wish to avoid MSG to do so, as they can check the labels before purchasing products.

MSG is deemed safe by Food Standards Australia
Monosodium glutamate (MSG) is deemed safe by Food Standards Australia, although some people experience mild hypersensitivity reactions to large amounts of MSG consumed in a single meal. These reactions are not considered allergies or intolerances but sensitivities, and the symptoms are not long-lasting. MSG is a sodium salt of glutamic acid, which occurs naturally in foods such as tomatoes, cheese, meat, and seaweed. It was first extracted from seaweed in Japan in 1908 and has since been used as a flavour enhancer in cooking, particularly in Asian cuisine.
MSG has been the subject of controversy, with some people believing it to cause adverse health effects such as headaches, nausea, and heart palpitations. However, blinded tests have not provided strong evidence to support these claims. The U.S. Food and Drug Administration has given MSG a "generally recognized as safe" (GRAS) designation, and it is widely used in the food industry as a flavour enhancer and preservative.
Food Standards Australia New Zealand (FSANZ) requires MSG to be labelled in packaged foods, listing the food additive class name, the name "MSG," or its International Numbering System (INS) number, 621. This helps consumers who may be sensitive to MSG to make informed choices.
While MSG is deemed safe by Food Standards Australia, it is important to note that excessive consumption may lead to high blood pressure. Some individuals may choose to avoid MSG due to personal preferences or health considerations.
In summary, MSG is deemed safe by Food Standards Australia, but it is important for individuals to monitor their consumption and be aware of any sensitivities or reactions they may experience.

Some people experience adverse reactions to MSG
Monosodium glutamate (MSG) is deemed safe by food authorities around the world, including Food Standards Australia. It is a legal food additive in Australia and is found in many Asian sauces, stock cubes, and snacks. However, some people experience adverse reactions to MSG, with symptoms such as headaches, nausea, heart palpitations, flushing, and asthma. These reactions are known as MSG symptom complex or Chinese Restaurant Syndrome, and while not considered an allergy or intolerance, they are classified as a sensitivity.
The adverse reactions to MSG have been widely reported, with the Mayo Clinic website stating that the FDA has received numerous anecdotal reports of adverse reactions to foods containing MSG. However, blinded tests have not provided strong evidence of a link between MSG and these symptoms. A 1993 study found that out of 71 fasting participants who were given 5 grams of MSG, only one self-identified MSG-sensitive individual reacted to the placebo. Similarly, a 2000 study tested the reaction of 130 subjects with reported sensitivity to MSG, and only two people responded to all four challenges.
The Punjab Food Authority in India has banned Ajinomoto, commonly known as Chinese salt, which contains MSG. Additionally, GIMDES, the Halal Certifying Body in Turkey, has also declared that MSG is harmful to human health and must not be used in food production. However, food authorities in Australia and other countries continue to deem MSG safe for consumption.
It is important to note that MSG is found naturally in some foods, such as tomatoes, cheese, Parmesan, mushrooms, meat, kombu, and Vegemite. The human body processes all glutamates, both natural and processed, in the same way. Therefore, a sensitivity to MSG would also apply to foods where glutamates occur naturally. For example, people who are 'MSG sensitive' may experience no problems with Vegemite or Parmesan cheese, which contain naturally occurring glutamates.
While MSG is generally recognized as safe, some individuals may experience mild hypersensitivity-type reactions when consuming large amounts in a single meal. These reactions are expected to pass quickly and not produce any long-lasting effects. However, it is recommended that those who experience adverse reactions to MSG familiarize themselves with the various names and numbers it goes by and check labels before purchasing products. When dining out, individuals can also request that their food be prepared without MSG.

MSG is naturally present in many foods
Monosodium glutamate (MSG) is naturally present in many foods. It is a sodium salt of glutamic acid, an amino acid that is a building block of protein. MSG is commonly added to foods as a flavour enhancer, giving them a savoury or umami taste. However, it is also naturally occurring in various protein-rich foods, including meat, eggs, and cheese.
MSG is particularly prevalent in cured or fermented foods, as the ageing process increases the food's free glutamate content. For example, cured ham contains significantly more free glutamate than fresh pork. Similarly, aged cheeses tend to have higher levels of MSG than fresh cheeses. The ripeness of fruits and vegetables also impacts their free glutamate content, with riper produce having higher levels of MSG.
MSG was first identified as a flavour enhancer by Japanese researchers in 1908, who isolated it from kombu, an edible seaweed used in Japanese cuisine. Since then, MSG has become a widely used additive in food production, especially in processed and fast food. While it is generally recognized as safe by organizations like the FDA, some people choose to avoid it due to concerns about potential adverse health effects.
Some of the foods that naturally contain MSG include:
- Tomatoes and tomato products
- Cheese, especially aged or fermented varieties
- Meat, particularly cured or processed meats like sausages and beef jerky
- Eggs
- Milk
- Fish
- Seafood
- Fermented sauces
- Fruits and vegetables, with riper ones having higher MSG content
- Nuts

MSG is commonly used in Asian cooking
Monosodium glutamate (MSG) is commonly associated with Chinese food and Southeast Asian cooking. However, it is also used in many non-ethnic restaurants and fast-food joints. MSG is a flavour enhancer that is added to various dishes and packaged foods to lend a savoury, rich umami flavour. It is made from sodium and L-glutamic acid, an amino acid that occurs naturally in umami-rich foods like tomatoes, anchovies, mushrooms, and Parmesan cheese.
The history of MSG in Asian cooking dates back to 1908, when Japanese cooks discovered that the unique taste of their dashi broth, made with kombu (edible seaweed), had a savoury taste not yet scientifically described. Kikunae Ikeda of Tokyo Imperial University isolated glutamic acid as the substance responsible for this delicious taste, naming it "umami". He then created the first man-made MSG, and commercial production began in 1909.
While MSG is commonly used in Asian cooking, it is important to note that it has been associated with certain side effects in a small subset of the population. Less than 1% of people may experience sensitivity to MSG, with symptoms including headaches, skin flushing, sweating, nausea, numbness, and fatigue. However, blinded tests have not provided strong evidence that MSG causes these symptoms. The stigma surrounding MSG may also be tied to racial stereotypes and xenophobic biases against East Asian societies and cuisine.
