What You'll Learn
MSG is a flavour enhancer that occurs naturally in mushrooms
Monosodium glutamate, or MSG, is a flavour enhancer that is commonly added to food. It is derived from glutamic acid, a type of protein that can be found naturally in many foods, including fruits, vegetables, and even breast milk. MSG is also produced through a fermentation process and brings a savoury taste known as "umami".
MSG occurs naturally in many foods, including mushrooms. In fact, mushrooms are known to have high concentrations of MSG. The natural flavour-enhancing levels of glutamate in mushrooms are high, and they are often used to enhance the flavour of dishes.
MSG was discovered by Japanese chemist and university professor Kikunae Ikeda in 1907. He observed his wife preparing a homemade broth using kelp for yudofu (boiled tofu) and became inspired to capture and replicate the delicious taste of the broth. After some trial and error, he discovered that the key to the amazing taste was the amino acid monosodium L-glutamate.
Today, MSG is a staple ingredient in many Japanese kitchens, and Japan hails Ikeda as one of its greatest inventors. Despite its controversial reputation, MSG is widely accepted in the scientific community as a safe additive. The US FDA has classified MSG as a food ingredient that is "generally recognized as safe".
When used in cooking, MSG can enhance the flavours of many dishes, including meats, poultry, seafood, and vegetables. It is often added to soups, stews, meat-based sauces, and snack foods. MSG works well with salty and sour tastes but does not enhance the flavours of sweet dishes.

MSG is a safe additive, despite its controversial reputation
Monosodium glutamate (MSG) is a common food additive that delivers a savoury taste known as umami. It is popular in Asian cooking and is used in various processed foods in the West. MSG is naturally found in foods such as tomatoes, mushrooms, walnuts, and cheese. It is also present in human breast milk.
Despite its ubiquity, MSG has a controversial reputation. Some people question its long-term health effects, and there is a popular belief that MSG can cause headaches and other feelings of discomfort, known as "Chinese restaurant syndrome". However, blinded studies have not provided strong evidence of this, and health authorities such as the Food and Drug Administration (FDA), the Joint FAO/WHO Expert Committee on Food Additives (JECFA), and the European Food Safety Association (EFSA) consider MSG to be generally recognized as safe (GRAS). These organizations have determined an acceptable daily intake (ADI) of 14 mg per pound (30 mg per kilogram) of body weight per day, which is far more than the amount typically ingested through food.
The controversy surrounding MSG may be due to a misconception. There is no chemical difference between the glutamic acid found naturally in some foods and that found in MSG, so your body cannot differentiate between the two types. Additionally, research has shown that it is not possible to be allergic to MSG itself, only to foods that contain it.
In conclusion, while MSG may have a controversial reputation, it is generally recognized as a safe additive by health authorities. As with any food additive, moderation is key, and excessive consumption of MSG or any other ingredient should be avoided.

MSG is a staple in many Japanese kitchens
Monosodium glutamate, or MSG, is a common food additive that delivers umami flavour. It is often associated with processed foods, but it is also found naturally in certain foods like tomatoes, walnuts, mushrooms, and cheese. MSG was discovered by Japanese chemist Kikunae Ikeda in 1907, and it has since become a staple in many Japanese kitchens. Ikeda was inspired by his wife's homemade broth, which used kelp to create a distinct and delicious taste. After some experimentation, he identified the key ingredient as monosodium L-glutamate, an amino acid.
MSG is now widely used in Japan and is hailed as one of the country's greatest inventions. It is known as "ajinomoto" or the "quintessence of flavor." While it has a bad reputation in some parts of the world, with some people avoiding it due to allergies or sensitivity, it is an essential ingredient in Japanese cuisine. The savoury, nutty, or "earthy" flavour of MSG enhances the taste of dishes without adding specific meat flavours.
In Japan, MSG is commonly used in soup stocks, which are a base for many traditional dishes. It is also found in bottled sauces, packaged snacks, instant noodles, and fast food. When dining out in Japan, it can be challenging to avoid MSG, especially in cheaper restaurants. However, by avoiding junk food and convenience foods, those with allergies or sensitivities can manage their exposure. Asking for information about ingredients in restaurants or checking packaging in stores can help identify the presence of MSG.
While MSG is a synthetic form of glutamic acid, it is identical to the glutamic acid produced naturally in the human body. This means that there is zero difference between the natural and synthetic forms, and the body cannot distinguish between them. Despite its controversial reputation, MSG is a valued ingredient in Japan, contributing to the unique flavour profile of Japanese cuisine. Its discovery by Ikeda over a century ago continues to shape the country's culinary traditions and influence cooking practices worldwide.

MSG is the sodium salt of glutamate
Monosodium glutamate (MSG) is a sodium salt of glutamic acid, which is one of the most common amino acids found in nature. Amino acids are essential building blocks of proteins, and glutamic acid is produced in abundance in the human body. MSG is created when sodium is added to glutamic acid.
MSG was discovered in 1907 by Japanese chemist and university professor Kikunae Ikeda, who was inspired by his wife's homemade broth using kelp for yudofu (boiled tofu). He identified that the delicious taste of the broth was due to the presence of glutamic acid, which he isolated from seaweed (kombu) in 1908, calling its taste umami, meaning "delicious taste".
The process of extracting MSG was patented by Ikeda, and he began marketing this seasoning as Ajinomoto, the "quintessence of flavor". MSG is now a staple ingredient in many Japanese kitchens, and it is recognised as a flavour enhancer in kitchens worldwide.
MSG is produced through the bacterial fermentation of plant-based ingredients such as sugar cane, sugar beets, cassava, or corn. During fermentation, the amino acid L-glutamate is isolated from a culture broth created by the excretion of Corynebacterium species cultured with ammonia and carbohydrates.
MSG is freely soluble in water and stable under food-processing conditions. It does not break down during cooking and exhibits a Maillard reaction (browning) at very high temperatures in the presence of sugars. MSG contains about 12% sodium, which is significantly less than the sodium content of table salt, which is about 39%.

MSG is not exclusive to processed foods
Monosodium glutamate, or MSG, is a flavour enhancer derived from glutamic acid, a type of protein that can be found naturally in many foods, including fruits, vegetables, and even breast milk. While it is commonly associated with processed foods, MSG is not exclusive to these items.
MSG occurs naturally in various foods, including mushrooms, tomatoes, walnuts, and many cheeses. These foods are known to have concentrations of MSG, providing them with a unique savoury taste known as umami. Umami is described as a soothing balance that gives a resounding "mmm" factor to food. It is considered the fifth taste, independent of the four basic tastes of sweet, sour, salty, and bitter.
Mushrooms, in particular, are a good source of natural MSG. Dried shiitake mushrooms, for example, have a high glutamate content of 1060 mg/100g, making them a rich source of umami flavour. This is why mushroom powder is often suggested as an alternative to MSG in cooking. While MSG provides a more subtle enhancement of flavours, mushroom powder can add depth and umami to dishes.
The human body treats glutamate from MSG the same as the natural glutamate found in food. The body does not distinguish between the glutamate from tomatoes, cheese, or mushrooms and the glutamate from MSG added to foods. This means that consuming MSG can provide similar flavour-enhancing effects as the glutamate that occurs naturally in food.
In summary, while MSG is commonly associated with processed foods, it is not exclusive to these items. MSG occurs naturally in various foods, including mushrooms, and provides a savoury umami flavour that enhances the taste of dishes.
