Is MSG In Soy Sauce?

Yes, MSG is present in soy sauce. In fact, it’s one of the reasons why soy sauce has such a distinct and delicious flavor.

MSG, or monosodium glutamate, is a flavor enhancer that is commonly used in many foods to boost their taste. It’s found naturally in some foods, such as tomatoes and cheese, but is often added to processed foods to enhance their flavor.

Soy sauce contains MSG because it is a byproduct of the fermentation process used to make soy sauce. However, some manufacturers also add additional MSG to their soy sauce to make the flavor even stronger.

While there are concerns about the potential health risks associated with consuming too much MSG, the amount found in soy sauce is generally considered safe for most people.

What Is MSG?

MSG, or monosodium glutamate, is a flavor enhancer that is commonly used in many foods to boost their taste. It is a mix of salt and glutamate, which is an amino acid that is both naturally occurring and synthesized. Glutamate is responsible for the umami flavor, which is the hard-to-describe “fifth taste” alongside saltiness, sourness, bitterness, and sweetness. Umami makes things taste meaty, savory, and substantive.

MSG is found naturally in some foods, such as tomatoes and cheese, but is often added to processed foods to enhance their flavor. It works by stimulating the taste buds and enhancing the flavors of other ingredients in a dish. MSG can be found in a variety of foods, including soups, sauces, dressings, seasonings, and snacks.

While there are concerns about the potential health risks associated with consuming too much MSG, the amount found in soy sauce and other foods is generally considered safe for most people. However, some people may be sensitive to MSG and experience symptoms such as headaches or nausea after consuming it. If you are concerned about consuming MSG or have experienced symptoms after consuming it in the past, it’s best to speak with a healthcare professional.

The Controversy Surrounding MSG

Despite being deemed safe by regulatory agencies, MSG has been the subject of controversy for decades. Some people report experiencing symptoms such as headaches, sweating, and nausea after consuming foods containing MSG, which has led to the term “Chinese Restaurant Syndrome.” However, scientific evidence linking MSG to these symptoms is lacking.

There have been some studies that suggest a possible link between high MSG intake and an increased risk of obesity, metabolic syndrome, and other health issues. However, these studies are limited and more research is needed to fully understand the potential risks of consuming MSG.

The controversy surrounding MSG has also led to the development of alternative flavor enhancers. Many people opt for natural ingredients like herbs and spices to boost the flavor of their food instead of using MSG.

The History Of Soy Sauce

The origins of soy sauce can be traced back to ancient China, where a sauce called “jan” was used for pickling raw materials in salt to preserve them. There were various types of “jan” based on different ingredients such as fruit, vegetables, seaweed, meat, and grains. The grain-based “jan” made from rice, wheat, and soybeans is believed to be the prototype of soy sauce.

It’s not clear when soy sauce was introduced to Japan, but historical records indicate that a sauce called “hishio” made from soybeans was produced at the hishio institute belonging to the cuisine division of the Imperial Household Agency. Hishio was similar to miso paste and was served at palace banquets.

The making of miso paste using the Kinzanji method was introduced to Japan by a Zen monk named Kakushin in 1254. While teaching the villagers of Kishu Yuasa how to make miso paste, Kakushin noticed that the liquid that seeped out of hishio tasted delicious. This liquid eventually became known as “tamari soy sauce.”

Over time, soy sauce production techniques evolved and became more refined. Today, there are many different types of soy sauce available, each with their own unique flavor profile and production methods. Despite its long history and widespread use, there are still misconceptions about the safety and health effects of consuming MSG in soy sauce. However, as mentioned earlier, MSG is generally considered safe when consumed in moderation.

Traditional Vs. Modern Soy Sauce Production

Traditional soy sauce production is a time-consuming process that involves natural fermentation and aging. The ingredients used are soybeans, wheat, salt, and mold cultures such as Aspergillus oryzae. The first step is soaking and cooking the soybeans, while the wheat is roasted and crushed. Then, the two ingredients are mixed with the mold culture to create a grain mixture called koji. The koji mixture is left to ferment naturally in large urns for several months under the sun. During this time, the mold breaks down the grain proteins into free amino acids and protein fragments, while starches are converted into simple sugars.

Lactic acid bacteria and yeast are then added to the mixture to undergo secondary fermentation, where they help produce numerous flavor compounds typical of soy sauce. Finally, the fully fermented grain slurry is pressed to separate the solids from the liquid soy sauce. The liquid is then pasteurized to eliminate any active yeasts and molds remaining in it.

In contrast, modern soy sauce production involves a more controlled process that uses temperature and humidity-controlled incubation chambers instead of natural fermentation. The ingredients and mold cultures used are similar to those used in traditional methods, but the process takes much less time. This allows for faster production of soy sauce on a larger scale.

While modern methods may be more efficient, some argue that traditional methods produce a richer and more complex flavor profile. Additionally, traditional methods may have some health benefits as they do not involve any artificial additives or preservatives.

The Health Effects Of Consuming MSG

There has been a lot of controversy around the health effects of consuming MSG. Some studies have linked MSG to obesity, metabolic disorders, brain toxicity, and MSG symptom complex (MSC), which includes symptoms such as headaches and sweating. However, recent research has debunked these claims and shown that in small amounts, MSG does not cause any significant or lasting harm.

Registered dietitian Beth Czerwony explains that there is no convincing evidence that MSG is a significant factor in causing severe illness or mortality. Studies conducted on Chinese restaurant syndrome (CRS) have largely failed to demonstrate a causal association with MSG. Symptoms resembling those of CRS may be provoked in a clinical setting in small numbers of individuals by the administration of large doses of MSG without food. However, such effects are neither persistent nor serious and are likely to be attenuated when MSG is consumed with food.

In terms of more serious adverse effects such as triggering bronchospasm in asthmatic individuals, the evidence does not indicate that MSG is a significant trigger factor. American scientists have used validated scientific methods to independently verify that MSG is safe to consume. The FDA has given it Generally Recognized as Safe (GRAS) status since 1958, and the Joint Expert Committee on Food Additives (JECFA) of the United Nations Food and Agriculture Organization (FAO) and the World Health Organization (WHO) concluded that no upper intake limit was necessary for MSG, placing it in the safest category of all food additives.

While some people may experience symptoms such as headaches and sweating after consuming food containing MSG, the amount found in soy sauce is generally considered safe for most people. It’s important to note that consuming large amounts of any food additive, including MSG, can have negative health effects. As with any food or ingredient, moderation is key.
