Ajinomoto or mono sodium glutamate (MSG)

Recent ruckus on use of MSG in many food preparations has created curiosity about this condiment. I am putting my findings of this important condiment here for my readers. If there is any objection because it is a foreign condiment then I would like to point out to them that almost 70% of vegetables we eat are of foreign origin. If we do not mind using potato, tomato, red chilly and many such everyday vegetables why object to MSG? Many vegetables such as sweet potato are used in preparations of offerings on fasting on religious occasions. These observations show that this resistance to MSG does not have any sensibility.

Kikunae Ikeda was inventor of Mono Sodium Glutamate.
Mono Sodium Glutamate was invented in 1908 by Dr. Kikunae Ikeda of Tokyo Imperial University based on research for the purpose of commercializing as seasoning the component of kombu (a type of seaweed) that produces its good taste.

Taking a hint from the taste of kombu, Dr. Ikeda thought that a flavor other than sweet, sour, bitter, salty, astringent and pungent (spicy hot) existed and proceeded to ascertain its original form. This flavor is called "MSG" in Japanese and is best translated as "delicious." His experiments resulted in the discovery that the "delicious" flavor of kombu comes from mono sodium glutamate, and Dr. Ikeda invented a method of obtaining crystalline mono sodium glutamate, the flavor in its purest form. Commercial production of this mono sodium glutamate was carried out by Saburosuke Suzuki, the founder of Ajinomoto Co., Inc., under request from Kikunae Ikeda. Dr. Ikeda's invention, sold under the Ajinomoto name, has become popular as a seasoning not only in Japan, but worldwide. It is said that initially when this condiment was introduced in the Japan home market no body was the taker as Japanese housewives were rather orthodox in their food habits in those days. Then Ajinomoto was introduced in Chinese market and it was received with great interest. Later on Chinese made it an essential part of their cooking. Ajinomoto is a Japanese word meaning "king of tastes" or great taste. Ajino means taste. Mono sodium glutamate is often mentioned as MSG. Even though it is a Japanese product world over it is known as a Chinese condiment.
According to Indian cuisine sweet, sour, bitter, hot (pungent, spicy, तीख्खा), salty and astringent are basic six tastes. Mono sodium glutamate is Astringent in taste. Normally this taste is not found in any edible matter. A proper combination of sweet (glucose) and Alum can give taste similar but not exactly same of this mono sodium glutamate.
By Aurvedic specification "MSG" has following qualities (गुण). Digestive (पाचक), mild purgative (सारक), Carminatives (वातहारक), Stomachic (दिपन), Alternative (रसायन), Cholagogues (पित्तहारक), Astringent (ग्राही). Looking to these qualities of MSG more research is required to find out its uses as medicinal product in both Homeopathy and other medical therapies.


It is wrongly said that mono sodium glutamate or Ajinomoto is dangerous to health. Actually even after extensive investigation it could not be proved. Use of MSG or Ajinomoto should be similar to common salt. Any extra addition does not help improve taste of food any more. Ajinomoto improves taste of starchy and meaty food, adding it in other preparations does not help in any way. MSG is a seaweed product and so it is made out of pure vegetative origin. Kombu is eaten by Japanese people for many centuries. They never experienced any unhealthy effect or any incidence of development of cancer and so any propaganda that this salt of glutamate is causing cancer; is absolutely baseless and ill motivated. In Indian cuisine we use green condiments such as kadipatta, fudinaa (fenugreek), Dhania (kothimbir, Coriander) and Ginger; similarly dried kombu was used in Japanese preparations. It is a perfectly vegetarian condiment. Kombu is a natural seaweed and so the extract from it, is acceptable to Aurvedic preparations. Ajinomoto has slight preservative property and so when added to food it helps improve the keeping properties of that preparation. Reasonable proportion recommended is about one teaspoonful for 1kg food preparation.


Indian food preparations are such that as one starts eating food a gas formation takes place in the digestive system. That makes one feel that his stomach is already full. After some time the gas is absorbed in the system and he can eat more. When MSG is added this is avoided and so one can eat food properly. This particular quality of MSG has made it popular all over the world. Actually it is experienced that one eats more food treated with MSG (Ajinomoto).
If one wants to avoid use of MSG then to avoid possibility of gas formation food should be prepared as given here, all protein products such as Dal (pulses) and Meat preparations, which cause gas formation, should be first either fried (tossed) in oil or slightly roasted and then used. Frying and roasting removes this gas in the protein material in the Dal (pulses) or Meat. If MSG is added, even after fried or roasted food, it offers no advantage. That means light frying or proper roasting is doing the same effect as MSG. Of course, unique astringent taste that this salt of mono sodium gives is an additional point in favor of MSG.
When first this seasoning was introduced in India in 1934, after First World War in Mumbai, Ajinomoto was called Chinlon (meaning salt from China) by local cooks. Many preparations were made using this salt however as Second World War began imports of this material were stopped. And housewives of Mumbai also forgot it until it was again introduced in the recent time. In India one company is franchisee of Ajinomoto corporation of USA, I wonder why that company is saying nothing against the objections raised against MSG?

In U.S a law case was filed on it some years back and it was proved then that MSG is not a pollutant or any toxic. MSG in right proportion is working as a preservative also. As of being allergic some tests were performed in U.S and it was proved that it was only imagination of those people who claimed to be having allergy of MSG. Glutamate segment in this salt is essential element in our body's protein and our body needs it to build muscles.

Two groups of people who claimed that they had allergy due to eating MSG were prepared and they were given to eat preparations made by using MSG and other without MSG. One group was given food without MSG but were told that it contains MSG and they began to show allergy effects; this proved that allergy is only some imagination and there is no sense in it. Other group was given food with MSG but they were told that the food does not contain MSG and they did not show any signs of allergy even after eating food made with MSG. Again proving that allergy is some sort of imagination of these people. I some times wonder why our (so called) experts are behaving like senseless all the time.

In view of these findings I suggest that our FD department who is creating scene about this harmless condiment must prove their point in a scientific manner.
