Monosodium Glutamate Facts

Monosodium glutamate (MSG) has been used to enhance the flavor of food for more than 100 years. It was originally synthesized by Japanese biochemist Kikunae Ikeda in 1908 after he realized that the Japanese broth called dashi (a basic stock made with seaweed and dried fish) had a meaty flavor that had not yet been identified. He called this flavor umami, which can be translated as "delicious taste" and set about synthesizing the main source of it. The basic sensory function of MSG is attributed to its ability to enhance savory taste-active compounds when added in the proper concentration

MSG, which first hit the market in 1909, is today created by bacterial fermentation in a process similar to that used in making yogurt.

Monosodium glutamate added to foods produces a flavoring similar to the glutamate that occurs naturally in foods. It acts as a flavor enhancer and adds a fifth taste, called umami, which is best described as a savory, broth-like or meaty taste.

In the European Union, monosodium glutamate is classified as a food additive (E621) and regulations are in place to determine how and when it can be added to foods. Typically, monosodium glutamate is added to savory prepared and processed foods such as frozen foods, spice mixes, canned and dry soups, salad dressings and meat or fish-based products. In some countries, it is used as a table-top seasoning.

Scientific studies have not shown any direct link between monosodium glutamate and adverse reactions in humans. The US Food and Drug Administration has given MSG its generally recognized as safe (GRAS) designation. While a popular belief holds that large doses of MSG can cause headaches and other feelings of discomfort, in controlled studies scientists have been unable to consistently trigger reactions. MSG has been used for more than 100 years to season food, with a number of studies conducted on its safety. International and national bodies governing food additives currently consider MSG safe for human consumption as a flavor enhancer.

MSG contains about one third of the sodium of table salt and is used in smaller amounts.

Children metabolize glutamate in the same way that adults do and monosodium glutamate is safe for children. In fact, human breast milk contains ten times more glutamate than cow’s milk.

When added to food, MSG provides an umami-rich flavor boost that regular table salt doesn't, even though MSG contains sixty percent less sodium than table salt, and many people cook with it regularly (it is sold under the brand name Accent). While it doesn't have much of a flavor on its own, when added to other foods it blends, balances, and rounds out the other flavors that are present.

MSG does not occur naturally in whole foods, so you do not have to worry about it in fruits and vegetables.

The human body also produces glutamate and it plays an essential role in normal body functioning.

What's in a Name, Viagra

The official name is Sildenafil Citrate. Pharmaceutical chemists at Pfizer's research facility in Kent, England originally conceived it as a treatment for hypertension, angina, and other symptoms of heart disease. Clinical trials during 1991 and 1992 revealed the drug was not great at treating what it was supposed to treat, but eighty percent of male test subjects were experiencing a side effect of erections.

It was finally approved by the US FDA in 1998 and the drug took US markets by storm as a treatment for penile dysfunction and became an overnight success. It and female Viagra now raise over two billion dollars a year.
