What is Liquid Seasoning?
Liquid seasoning is a category of savory, concentrated sauces used as flavor enhancers worldwide. The most well-known brands include Maggi, Bragg's Liquid Aminos, and Knorr. Its exact composition varies significantly between brands and even regional formulations, but it generally consists of a base of hydrolyzed vegetable protein, which is broken down with acid to release amino acids. This process yields naturally occurring glutamic acid, the source of its umami flavor.
Unlike traditional soy sauce, which is fermented from soybeans, liquid seasonings are often derived from hydrolyzed wheat protein, soy protein, or a mix of vegetable extracts. This difference in manufacturing results in distinct flavor profiles. Liquid seasoning is typically richer, more concentrated, and more complex in flavor than standard soy sauce, with some varieties adding a beefy or slightly sweet note. It is used sparingly to boost the savory depth in soups, stews, sauces, marinades, and even simple dishes like eggs or fried rice.
What is MSG?
Monosodium glutamate (MSG) is a specific sodium salt of the amino acid glutamic acid. It is the purest form of umami taste, a flavor profile described as savory or meaty. MSG was first identified and isolated in 1908 by Japanese biochemist Kikunae Ikeda from seaweed broth. Today, MSG is most commonly produced through the fermentation of starches or sugars, in a process similar to making yogurt or vinegar.
MSG is not a seasoning in itself but a neutral flavor enhancer that intensifies the existing savory taste of food. Unlike liquid seasoning, which adds its own distinct set of flavors, MSG provides a clean umami boost without altering the food's other taste characteristics. It contains about one-third of the sodium found in table salt and can be used to reduce overall sodium content while maintaining palatability. MSG is added to a wide range of products, including snacks, canned soups, processed meats, and seasoning blends.
Are All Liquid Seasonings the Same? The Ingredients Tell the Story
To fully understand the difference, it is crucial to examine ingredient labels, as not all liquid seasonings are created equally. The presence of added MSG is a key differentiator.
- Liquid Seasonings with Added MSG: Some products, such as specific formulations of Maggi and Knorr liquid seasoning, explicitly list 'monosodium glutamate' or 'flavor enhancers (MSG)' on their ingredients list. These products are a blend of hydrolyzed protein and added MSG to maximize the umami effect. Different regions have different formulas, so one country's Maggi may differ from another's.
- Liquid Seasonings without Added MSG: Brands like Bragg's Liquid Aminos pride themselves on not adding MSG. Their umami comes purely from the glutamates that are naturally present after the hydrolysis of soy protein. The label will not list MSG as an ingredient, though it will often state 'hydrolyzed vegetable protein' or 'soy protein'.
Liquid Seasoning vs. MSG: A Comparison Table
| Feature | Liquid Seasoning | MSG (Monosodium Glutamate) |
|---|---|---|
| Composition | Concentrated liquid sauce with multiple ingredients. | Crystalline powder, a specific sodium salt of glutamic acid. |
| Ingredients | Hydrolyzed vegetable protein (wheat or soy), water, salt, flavorings, and sometimes added MSG. | Glutamate and sodium, produced via fermentation. |
| Flavor Profile | Complex, salty, savory, and umami-rich, with notes specific to the brand (e.g., beefy, herbaceous). | Pure umami flavor, neutral in taste until combined with food. |
| Function | Adds a specific flavor profile and salty umami depth to dishes. | Amplifies the natural savory flavor of food without adding distinct flavor notes. |
| Sodium Content | Generally high, but varies by brand. | Lower than table salt (one-third the sodium). |
| Usage | Drizzled in sauces, marinades, soups, and dishes where a strong, savory base is desired. | Can be sprinkled on food or added to recipes where a pure umami boost is needed. |
When to Use Liquid Seasoning vs. MSG
Choosing between liquid seasoning and MSG depends on your culinary goal. For dishes where you want a complex, savory, and slightly salty flavor base, liquid seasoning is the ideal choice. Its robust profile is perfect for marinating meats, adding depth to stews, or seasoning soups. For example, a Filipino dish like Chicken Inasal often uses Knorr liquid seasoning to achieve its signature rich and savory flavor.
Alternatively, if your goal is to simply elevate the existing savory notes of a dish without introducing new flavors or extra saltiness, MSG is the superior option. It can be used to add a subtle pop of umami to scrambled eggs, spice blends, or sauces. A pinch of MSG can make a simple tomato sauce taste richer or a vegetable stir-fry more satisfying. It can also be used as a salt replacement to reduce overall sodium content. For example, adding MSG to a chicken broth, as discussed by Ajinomoto, can reduce sodium levels while maintaining flavor.
Conclusion: Not Identical, But Umami-Focused
In summary, liquid seasoning is definitively not the same as MSG. While both are used to enhance the umami flavor in food, they are fundamentally different products. MSG is a pure chemical compound that functions as a flavor amplifier, while liquid seasoning is a complex, multi-ingredient sauce that imparts its own distinct taste along with umami. The presence of added MSG in some liquid seasoning brands has created confusion, but a quick look at the ingredients list can clarify the difference. By understanding the unique properties of each, cooks can make an informed choice to achieve their desired flavor outcome, whether it’s a subtle savory lift or a robust, seasoned base.

Which Flavor Enhancer Should You Choose?
The choice between liquid seasoning and MSG hinges on whether you want to add a complex, seasoned flavor profile or simply amplify existing savory notes. If the goal is a bold, seasoned base for dishes like soups or marinades, liquid seasoning is the right tool. For a pure, neutral umami lift in a wider variety of foods, or for sodium reduction, MSG is the best choice.
What to Look for on Labels
To avoid confusion, always check the ingredients. If you see "Monosodium Glutamate," "Flavor Enhancer 621," or other numbered enhancers, the product contains added MSG. If the label mentions "hydrolyzed protein" from soy or wheat but does not list MSG, the umami comes from naturally occurring glutamates.
