Can You Avoid MSG in Soy Sauce? How to Choose Naturally Brewed Soy Sauce

March 13, 2026

Is it possible to avoid added MSG in soy sauce? Absolutely! It’s a common misconception that all soy sauces contain MSG. But that’s not the case. The answer is even more intriguing. The secret is to differentiate between the two. Long fermentation times create the flavors naturally and this is a vivid example of how one brand can profer not to add MSG. The brewery ain’t a shortcut. They just have the authentic flavor and don’t need to add MSG to it. A full-bodied, rich flavor is what you’re looking for. This article will demonstrate how to identify and differentiate them easily. You will choose pure, high-quality soy sauce for your kitchen. Thus, you will also get rid of the additives found in many many popular condiments and processed foods.

Glutamates from Nature vs. Added MSG

The umami thing will be our lens to look at the MSG theme first. You’ve probably eluded sweet, sour, salty, bitter and even the fifth basic taste known as umami. Now, we are going to discuss umami. The word is a Japanese term that implies a meat-like or savory taste.

The umami flavor actually comes from glutamic acid which is an amino acid. This acid is naturally present in a lot of foods that we really like. For example, ripe tomatoes, aged cheeses, mushrooms, and soybeans.

Monosodium glutamate (MSG) is a flavor enhancer. MSG is simply the salt of glutamic acid. Because it is stable in this form, it is easy to add it to foods, and this way, the umami taste becomes stronger.

This is where the difference is important.

Naturally Occurring Glutamates: This process is the result of proteins that break down over a long time without any interference. It takes soy sauce a long time to ferment the proteins from grain and soy. The deep flavor is complemented by many subtler weight compounds.
Added MSG: This is the product of manufacturing. Its purpose is to quickly give a food a strong umami taste. It is usually a symptom of a fast production cycle or the use of lower-quality ingredients.

Think of it as the sweetness in fruit. A fully ripened strawberry left in the sun has such a complex, rich sweetness. White sugar is just a single note sweet. It’s true, natural glutamates are the strawberry while added MSG is the plain sugar.

Brewing Methods: The Mystery of Soy Sauce and MSG

The main reason behind some soy sauces having added MSG hinges on the making process. There are two different approaches to do that. Realizing them is the key to finding a top-quality item.

Traditional Fermentation

It is THE way of doing things that has been passed down through generations. High-quality soybeans and sometimes wheat are taken. The initial step is to mix them with a special kind of starter culture known as koji. A saltwater brine is then added to the mix, which will be referred to here as moromi. This moromi mix is left for fermentation in the large container for months or even years. Throughout this long and tedious process, the enzymes of koji carry out the soybeans’ biological and wheat protein breakdown actively. What is left is the amino acids of various kinds; glutamic acid is also there. This long time and the natural way of creating a soy sauce turns into a product full of umami and gas compound aroma. The logic of this is that methods like the High-Salt Dilute Authenticity Brew™ have to follow this rule. This plan is dedicated to salt and time without fast-track solutions. This is how it is done. The original, robust umami flavor is created without shortcuts. These products do not require added MSG at all. The incredible taste exists already.

Chemical Hydrolysis (Non-brewed)

This is a new industrial trend that fasts the production cycle. Instead of traditional fermentation, soybeans are boiled in a strong acid. Usually, it is hydrochloric acid. This process breaks down the proteins very quickly. Often in just a few days.

The product is an acrid liquid that is thin, dark, and lacking the aroma and complicated flavor that a good soy sauce should have. It’s merely one note.

In order for this liquid to thus replace a real soy sauce in terms of look and taste, manufacturers have to add things back in. One of them is caramel color that fakes the darkness. Another one is corn syrup that adds sweetness and body. Sanitized flavor enhancers such as added MSG for the savory taste are also used. If you want to go with soy sauce without MSG, take no products this way.

This is a simple table that sums it up:

Trait	Traditional Brewing	Chemical Hydrolysis
Procedure	Natural fermentation (months-years)	Acid breakdown (days)
Flavor Source	Naturally developed glutamates	Often requires added flavor enhancers
Taste Profile	Complex, rich, nuanced	Simple, harsh, one-dimensional
Likelihood of Extra MSG	Very low to none	High

How to Find Soy Sauce Without MSG

Therefore, what do you do with this knowledge in the shop? It’s simpler than expected. Due to our interest in crafting pure soy sauce we’ve learned that the ingredient label is truly your best friend. Below are the culprits in your hunt for soya sauce without MSG:

Step 1: Check the Ingredient List

It is your very strong weapon. Typically, a good quality, soy sauce that is made traditionally has a very minimal ingredient list.

Green Flags (What you want to see): Water, Soybeans, Wheat, Salt. Sometimes you might even see alcohol listed. This is a natural preservative.
Red Flags (What to avoid): Hydrolyzed Soy Protein, Yeast Extract, Disodium Inosinate, Disodium Guanylate, “Flavor Enhancers,” or “Natural Flavors.”

Words like “hydrolyzed soy protein” and “yeast extract” are red flags. They are the sources of processed glutamates that add umami flavors. They are a way for companies to avoid listing “MSG” directly. Also, there are many names for MSG that seem to be hidden on product labels.

Step 2: Search for the Words “Traditionally Brewed”

If you spot something along the lines of “Traditionally Brewed” or “Naturally Brewed”, that’s reassuring. The phrase shows that the maker has used the slow fermentation method. It’s also a guarantee to you when a log of the qualitative aspect of flavor developing is maintained, instead of just adding the compound in a laboratory.

Step 3: Check the Price

Time has a price and quality demands it. The month-long fermentation period and the use of high-quality ingredients are the reason traditional soy sauce is always more expensive than chemically produced sauces. If a huge bottle of soy sauce is ridiculously cheap, it could be a hidden issue; a shortcut might have been taken somewhere.

Step 4: Know Your Brands

The best idea is to stick with the brands you can believe in after finding them. Traditional soy sauce manufacturers are proud of what they do and normally will be honest about the ingredients. For people who are not seeking anything else but authentic, naturally fermented options, it can be eye-opening to go through a range of a manufacturer like Qianhe | Authentic Chinese Soy Sauce Wholesale and then see what a clear ingredient list looks like.

FAQ

Q1:Is "naturally occurring" glutamate the same as MSG?

No. Although they have a chemical connection, the naturally occurring glutamates are parts of a multi-faceted food matrix. The glutamates are bound to other amino acids and proteins. MSG is a refined, hygroscopic additive. Those people who often report the MSG sensitivity are the ones that are reacting to the high, concentrated dose of the added form. They don’t react to the natural ones found in foods such as cheese or soy sauce.

Q2:Does "No Added MSG" mean the product is completely free of glutamates?

Definitely not. This fact is of utmost importance. A pure soy sauce that is also labeled “No Added MSG” always has a considerable content of naturally occurring glutamates. That’s the secret of the deliciousness. You only taste the umami flavor. The only thing that can be said is that no MSG was added as a separate ingredient.

Q3:Is tamari a good MSG-free alternative to soy sauce?

Very fine, traditional tamari is a good choice. Besides being a soy product, tamari brand is mostly wheat free, which is good news.

Q4: Are dark soy sauce and light soy sauce more likely to have MSG?

No. The type of soy sauce (light vs. dark) doesn’t determine if it has added MSG. The quality of the brewing process is what matters. A high-quality dark soy sauce gets its darker color and thicker texture from a longer aging process. Sometimes molasses or caramel is added after brewing. Not from flavor enhancers.

Q5:Why do I feel unwell after eating restaurant food with soy sauce?

Many restaurants use bulk, lower-cost soy sauce. This is more likely to be chemically produced and contain added MSG. It could also be due to high sodium levels. Or a reaction to other ingredients in the dish. Asking about the soy sauce a restaurant uses can help. Choosing restaurants known for quality ingredients could be a factor.

Conclusion: The Choice is Yours and the Taste is Great

Can you avoid MSG in soy sauce in 2026? The unequivocal response is yes. The uncertainty in this matter disappears with the knowledge that production methodology is the paramount factor. You don’t have to omit this condiment entirely. The way to go is to learn to read labels smart. Use the products that have been traditionally and naturally brewed. By following the ingredients that are merely water, soybeans, wheat, and salt you will choose a product whose flavor comes from time and tradition rather than additives. That decision in turn guarantees restful days with honest, complex, and authentic flavors in your cooking.
