What is Sodium Succinate?
Sodium succinate is the disodium salt of succinic acid, a naturally occurring organic acid present in all plant and animal tissues. While succinic acid is naturally found in very small quantities in certain fermented products like wine and fermented beverages, the sodium succinate used as a food additive (E367) is manufactured for commercial use. In its food-grade form, it is a crystalline powder prized for its ability to intensify and harmonize savory, or umami, flavors. It serves as a buffering agent, helping to control the pH level in foods, which is essential for maintaining stability, inhibiting microbial growth, and preserving color and texture.
Processed Foods with Added Sodium Succinate
Sodium succinate is not something you would typically find in fresh, whole foods. Its application is most prominent in processed and packaged items where flavor consistency and enhancement are crucial. The following are some of the most common food categories where sodium succinate is used as an additive:
- Soups and Broths: Instant noodles, dehydrated soup mixes, and canned soups use sodium succinate to create a deeper, richer, and more satisfying umami flavor profile.
- Snack Foods: Products like flavored potato chips, crackers, and nuts frequently contain sodium succinate to boost their overall flavor intensity and enhance savory notes.
- Processed Meats and Seafood: Sausages, ham, deli meats, and certain canned or frozen seafood products utilize this additive to improve taste, retain moisture, and stabilize color.
- Seasoning and Flavoring Mixes: Sodium succinate is a key component in many seasoning blends, rubs, and sauce packets designed to add a complex umami depth to dishes.
- Dairy Products: Certain processed cheeses and dairy products may contain sodium succinate to improve their taste and texture.
- Canned and Processed Vegetables: Items like canned beans, olives, and pickled cucumbers benefit from sodium succinate, which provides flavor consistency and can act as a buffer.
- Frozen Foods: It is added to various frozen meals to help maintain food quality and flavor during storage.
- Sauces and Condiments: Soy sauce, certain salad dressings, and other savory sauces may contain sodium succinate to round out their flavor profile.
Umami Enhancement: A Key Function
One of the most notable characteristics of sodium succinate is its powerful synergistic effect when combined with other umami agents like monosodium glutamate (MSG). The combination produces a much richer and more complex flavor sensation than either compound used alone. This allows food manufacturers to use a lower concentration of both additives to achieve the desired flavor intensity, potentially reducing overall sodium content in the product while maintaining palatability. Its unique "shellfish taste" is often specifically sought after to complement seafood flavor profiles.
Sodium Succinate vs. Monosodium Glutamate (MSG)
While both are known for their umami-enhancing properties, sodium succinate and MSG differ in their flavor profile, how they are used, and the overall effect they produce. The following table compares these two popular food additives:
| Feature | Sodium Succinate (E367) | Monosodium Glutamate (MSG) |
|---|---|---|
| Flavor Profile | Distinct shellfish-like taste; primarily a harmonizing agent that rounds out other flavors. | More of a pure, impactful umami taste that acts on the back of the tongue. |
| Synergy | Strong synergistic effect with MSG and other umami agents, making it possible to use less of each for the same flavor effect. | Synergistic with succinates and other flavor enhancers, but acts as a powerful enhancer on its own. |
| Function | Acts as a pH buffer, flavor harmonizer, and preservative aid, in addition to umami enhancement. | Primarily and most famously used as a flavor enhancer to create a savory effect. |
| Usage | Often used in conjunction with MSG in savory dishes, sauces, and instant products. | Can be used alone or with other enhancers across a very wide range of savory foods. |
How to Identify Sodium Succinate on Food Labels
For consumers who wish to identify the presence of sodium succinate in their food, the best course of action is to check the ingredient list on packaged products. It may be listed as "sodium succinate", "disodium succinate", or by its European food additive code "E367". However, since it is often a minor ingredient used in combination with others, it may also be part of a broader "flavoring" or "seasoning mix" ingredient. Looking for the specific name or code is the most reliable method.
Conclusion
While a precursor acid naturally exists in living organisms, sodium succinate as a flavor additive is found almost exclusively in processed, packaged, and preserved foods. Its primary role is to enhance savory umami flavors, regulate acidity, and improve the overall palatability of products like soups, snacks, and cured meats. Recognized as safe for consumption within regulated limits by authorities like the FDA, it is a versatile tool for food manufacturers seeking to create a richer and more satisfying taste experience for consumers. Those curious about its use can check food labels for "sodium succinate" or its E-number, E367. For additional information on sodium succinate, its properties, and applications, you can consult reliable sources like the FDA's substance database.

Safety and Regulation
Like all food additives, sodium succinate is subject to strict regulatory oversight to ensure its safety for consumption. Organizations such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) have evaluated it and deemed it safe for its intended use when used within specified limits. These regulations ensure that the concentration of additives in food does not pose a health risk. As with any source of sodium, those on sodium-restricted diets should be mindful of their intake from all processed food sources, including those containing sodium succinate.
Responsible Usage in Food Manufacturing
The multi-functional nature of sodium succinate makes it a valuable additive for food manufacturers. By effectively boosting umami and stabilizing flavor, it allows for the use of less sodium chloride (table salt) to achieve a desirable taste. This supports efforts to produce healthier food products with reduced sodium content without sacrificing flavor. Its pH buffering and mild preservative properties further enhance product quality and shelf life, providing significant benefits to the food industry.
What is the takeaway about sodium succinate?
In summary, sodium succinate is a safe and regulated food additive found primarily in processed foods. It is used to enhance umami flavor, harmonize tastes, and regulate pH levels. It is not a staple in natural, unprocessed foods but is crucial for creating the complex savory profiles found in many packaged products. Awareness of its function and presence allows consumers to make more informed dietary choices.
Final Word on Natural vs. Added Succinate
It is important to distinguish between the small amounts of succinate that occur naturally in certain fermented items and the manufactured sodium succinate added to processed foods. The latter is what contributes to the distinct umami taste and other functional properties in packaged goods. While naturally present succinates are a part of a food's inherent chemistry, the added form is a deliberate ingredient used to achieve a specific flavor outcome.
