The Core Difference: Natural Glutamate vs. Added MSG
The most important distinction to understand is that all liquid aminos contain naturally occurring glutamate, but reputable brands do not contain added MSG. Glutamate is an amino acid and is one of the key building blocks of protein. When proteins are broken down during manufacturing or digestion, they release free glutamate. This free glutamate triggers the taste receptor for umami, the savory, meaty taste that is highly prized in cooking.
MSG, or monosodium glutamate, is the sodium salt of glutamic acid. While it is often industrially produced for use as a food additive, there is no chemical difference between this added glutamate and the free glutamate found naturally in foods like tomatoes, Parmesan cheese, and mushrooms. A product that claims "no added MSG" can still contain high levels of naturally occurring glutamate from its base ingredients.
How Liquid Aminos are Made
To better understand the glutamate content, it helps to know the production methods for different types of liquid aminos.
- Soy-Based Liquid Aminos: Brands like Bragg's Liquid Aminos are typically made through a process called acid hydrolysis. Soybeans are treated with hydrochloric acid, which breaks down the soy protein into its constituent amino acids. The remaining acid is then neutralized with sodium bicarbonate, a process that creates sodium chloride, or table salt, providing the signature salty flavor.
- Coconut Aminos: This popular soy-free alternative is made from fermented coconut blossom sap combined with sea salt. The fermentation process naturally releases free amino acids, including glutamate, from the sap's proteins.
In both processes, the breakdown of protein releases the amino acid glutamate, giving the final product its umami taste. The glutamate is inherent to the source ingredients, not an external additive.
Making Sense of the Label: "No Added MSG"
The phrase "no added MSG" is a key differentiator for consumers. It signals that a food manufacturer did not include MSG as a separate flavor enhancer. However, it doesn't mean the product is glutamate-free. For example, a tomato sauce manufacturer can state "no added MSG" because the high concentration of natural free glutamate comes directly from the tomatoes. Similarly, the umami taste in liquid aminos comes from the natural breakdown of the soy protein or coconut sap.
- For sensitive individuals: People who believe they have a sensitivity to MSG may need to pay attention to overall glutamate content, both natural and added. However, some adverse reactions attributed to MSG may actually be related to a more common soy allergy in the case of soy-based liquid aminos. Consulting with a doctor or dietitian is the best course of action.
- For the average consumer: The naturally occurring glutamate in liquid aminos is generally considered safe for consumption. The FDA classifies MSG as "generally recognized as safe" (GRAS) for the general population. The concern over MSG is largely unsubstantiated by scientific evidence for most people.
Comparison of Umami-Rich Condiments
| Feature | Liquid Aminos (Soy-Based) | Coconut Aminos | Soy Sauce (Traditional) |
|---|---|---|---|
| Source | Soybeans | Coconut blossom sap | Fermented soybeans and roasted wheat |
| Production | Acid hydrolysis | Fermentation | Brewing and fermentation |
| Gluten-Free? | Yes | Yes | No, contains wheat |
| Added MSG? | No | No | Can contain added MSG |
| Naturally Occurring Glutamate? | Yes | Yes | Yes |
| Sodium Level | High, but often less than traditional soy sauce | Lower than soy sauce and soy-based liquid aminos | High |
| Preservatives | None added (self-preserving due to salt) | None added | May contain chemical preservatives like sodium benzoate |
| Flavor Profile | Salty, savory, mild umami | Milder, sweeter, less intense umami | Salty, intense umami |
How to Use Liquid Aminos for Flavor and Nutrition
Liquid aminos can be used in a variety of culinary applications to enhance the flavor of dishes. They are an excellent substitute for soy sauce in marinades, dressings, and stir-fries, especially for those seeking a gluten-free or soy-free option.
- In salad dressings: Use it in place of salt or as a savory base for homemade vinaigrettes.
- For marinades: Add to marinades for tofu, vegetables, or meat to infuse with umami flavor.
- Stir-fries and soups: A splash can deepen the savory notes in stir-fries, broths, and stews.
- Seasoning: Drizzle over roasted vegetables or use as a seasoning for rice, popcorn, or other snacks.
For those interested in the potential health benefits, liquid aminos provide a source of amino acids, which are the building blocks of protein. However, because they are used in small quantities, the nutritional impact is relatively minor. The primary appeal remains their ability to deliver a robust, umami flavor without the chemical additives or gluten often found in other condiments.
Conclusion
To answer the question, "do liquid aminos contain MSG?", the answer is both no and yes, depending on how you interpret it. They do not contain added MSG as an ingredient. However, as a natural byproduct of breaking down soy or coconut protein, they are rich in naturally occurring free glutamate, the very substance that gives MSG its flavor-enhancing power. The human body processes both forms of glutamate in the same way, and for most people, there is no difference in effect. For those concerned about MSG as a food additive, liquid aminos provide a clean-label alternative that delivers the same delicious umami taste. The choice between liquid aminos, soy sauce, and coconut aminos often comes down to dietary restrictions, desired sodium level, and flavor preference.

The Final Verdict
Ultimately, whether liquid aminos are right for you depends on your personal health needs and culinary goals. If you are seeking a gluten-free, additive-free, and lower-sodium alternative to soy sauce that still provides a savory umami kick, liquid aminos are an excellent choice. Just remember that the savory taste comes from the natural presence of glutamate, not from a laboratory additive.
