Q1 What is MSG?
  • Monosodium glutamate (MSG) is the salt of sodium and glutamate, a natural occurring amino acid that is present in all proteins such as milk, meat, fish and many vegetables. In chemistry, mono- means one, thus monosodium refers to one molecule of sodium. MSG has been used for more than hundred years to enhance and balance the taste of many dishes. It adds umami taste, which is best described as savory, broth-like or meaty taste.
Q2 How is it made?
  • Glutamate is produced by fermentation of starch, sugar, beets cane or molasses. The fermentation process is similar to that used in making vinegar, soy sauce or yogurt. 
Q3 What is the difference between MSG and glutamate in foods?
  • The glutamate in MSG is chemically indistinguishable from the glutamate in foods of the glutamate in our body, they are all identical.
Q4 Does the human body process the glutamate occurring naturally in foods differently from the glutamate added to foods in the form of monosodium glutamate?
  • No. The body cannot distinguish the naturally occurring glutamate in food such as tomatoes or cheese from the glutamate in MSG. Once they are ingested, our body makes no distinction. In fact, researcher has shown that glutamate from food or from MSG is important for the normal functioning of the digestive systtem.
Q5 Is MSG safe to eat?
  • After more than forty years of extensive studies, international and national bodies dedicated to the safety of food additive have determined that MSG is safe for consumption as a flavor enhancer.
  • The U.S. Food and Drug administration considers the addition of MSG to foods "generally recognized as safe" (GRAS), similar to other ingredients like sugar, baking powder and vinegar. Foods are designated GRAS according to their common use and extensive testing. In the European Union MSG is a food additives that has been confirmed by scientific and regulatory bodies to be safe for human consumption. 
  • Although some people identify themselves as sensitive to MSG, scientists have not been able to consistently trigger reactions in double-blind studies with such individual using MSG or placebo.
Q6 Is MSG safe for infants and pregnant women?
  • MSG is safe for everyone without exception, including infants and pregnant women. Studies with infants showed they metabolize MSG in just the same way as adults. In facts, human breast milk contains 6 to 9 time higher glutamate than cow's milk. Infants can taste glutamate right after they are born. It is a taste they naturally prefer.
Q7 What is the so-called "Chinese Restaurant Syndrome"?
  • In 1968, accounts of reactions to food from Chinese Restaurant in the USA were reported. MSG was mistakenly blamed by some people as the cause for these symptoms, such as headaches or flushing, and the people who believed they had these reaction were considered sensitive to MSG. However, studies conducted by recognized medical research institutions fail to show a connection between MSG consumption and adverse reactions or side effects.
Q8 Does MSG cause allergy?
  • According to the U.S. National Institute of Allergy and Infectious Disease, the reaction that some people claim to have to certain additives such as MSG can be confused with food allergy when in fact it should be considered food intolerance. Some individuals claim to be sensitive MSG, but there are no known mechanisms that would explain the reason why MSG would cause any intolerance.
  • In comparison, food allergy is an adverse response from the body's immune system to a particular food that in rare cases can trigger a sever and life threatening reaction known as anaphylactic shock. Foods that most often generate allergic reaction are fish, shellfish, peanuts and nuts. 
  • For more information on food allergies visit the National Institute of Allergy and Infectious Diseases.
Q9 Dose MSG cause headache?
  • There is no consistent evidence as to whether MSG causes headache. And although headache was reported as one of the symptoms of the so-called "Chinese Restaurant Syndrome", human studies have not been able to prove it consistently. Headache appeared as a symptom in some studies and only when MSG consumed without food during fasting, which seems irrelevant because MSG is a flavor enhancer and would not be ingested without food.
Q10 Are there adverse effects caused by MSG?
  • The U.S. Food and Drug Administration (FDA) received reports of headaches and nausea form people that ate food containing MSG. To clarify whether MSG caused these effects, in the 1990s the FDA asked an independent scientific group, the Federation of American Societies for Experimental Biology (FASEB), to examine the safety of MSG. FASEB concluded that MSG is safe, but that some sensitive individuals may present some short-term, transient and generally mild symptoms (headaches, numbness, flushing, tingling, palpitations and drowsiness) after consuming 3 grams of MSG; although consuming 3 grams of MSG at once without food is a very unlikely event.
Q11 Will the addition fo increasing amounts of MSG make food taste even better?
  • The taste of MSG, like the taste of salt, is pleasant only within a relatively narrow concentration range. A small amount of MSG is sufficient to achieve optimum flavor. Further addition of MSG has little or no beneficial effect. In fact, too much MSG can reduce the appeal of a dish.
Q12 How can I tell if there is MSG in my foods?
  • Many countries require that packaging labels include MSG in the ingredient panel when they contain added MSG. However, foods may also include other food ingredients that contain inherently MSG like hydrolyzed vegetable proteins or yeast extracts. Other foods like cheeses or tomatoes are also naturally rich in MSG (glutamate).
Q13 Does the addition of MSG allow food manufacturers to substitute poor quality ingredients for high quality ingredients?
  • MSG adds umami taste and enhance the original flavor of foods, but MSG cannot improve the quality on inferior ingredients.
Q14 In wihch type of foods is MSG used?
  • MSG can be used in many savor dishes based on meat, fish, poultry of vegetables, as well as in sauces, soups and marinades.
Q15 Is the amount of glutamate added to foods for flavor greater than the amount of glutamate found naturally in foods?
  • The glutamate added to foods for flavor represents only a small fraction of the total amount of glutamate consumed in the average daily diet. Normally, a person consumes between 10 and 20 grams of glutamate every day. The average added intake of glutamate from MSG amounts to just 0.5 - 1.5 grams per day.
Q16 How macu sodium dones MSG contribute to food?
  • The amount of sodium from MSG is minor compared to table salt and othre food sources in the overall, only aobut 1 to 2% of total sodium contained int the average diet comes from MSG. Table salt has roughly 3 times more sodium than MSG and it is used more readily, where MSG is used in lesser quantities; it tastes stronger than table salt.

  • MSG is gluten-free.
Q18 What is the E-number for MSG?
  • E621.
