Disodium Succinate Hexahydrate, also known as Sodium Succinate Dibasic Hexahydrate or Succinic Acid Disodium Salt Hexahydrate, is the hydrated crystalline form of disodium succinate. Its CAS Number is 6106-21-4.

This white to almost white crystalline powder or solid has a slightly salty taste and functions primarily as a flavor enhancer. It is the hexahydrate version (most commonly used in food), distinct from the anhydrous form (CAS 150-90-3). It is highly water-soluble and insoluble in ethanol.

Benefits of Disodium Succinate Hexahydrate

Powerful Umami Enhancement:
Significantly boosts savory, seafood, and meat-like tastes, especially when combined with MSG, disodium inosinate/guanylate (I+G), or hydrolyzed vegetable proteins.

Synergistic Flavor Boost:
Amplifies overall flavor profile without overpowering other ingredients.

High Solubility:
Excellent dissolution in water-based systems for even distribution in soups, sauces, snacks, and seasonings.

Natural Profile:
Derived from succinic acid (a TCA cycle intermediate), offering a clean-label appeal in many markets.

Stability:
Performs well in various pH ranges and processing conditions common in food manufacturing.

 

Applications and Uses of Disodium Succinate Hexahydrate

Disodium Succinate Hexahydrate is approved for use as a flavor enhancer and flavoring agent or adjuvant in food products.

  • Seasonings and spice blends
  • Instant noodles, soups, and broths
  • Seafood-flavored snacks and products
  • Meat products and processed foods
  • Sauces, gravies, and condiments
  • Savory snacks (chips, crackers)
  • Flavor systems for vegetarian/plant-based alternatives

It is particularly effective in enhancing “seafood taste” and umami when used in combination with other enhancers.

 

Frequently Asked Questions (FAQs)

Q: Is Disodium Succinate Hexahydrate safe for food use?
A: Yes, it is recognized as safe for use as a flavor enhancer and flavoring agent/adjuvant.

Q: What is the main function of Disodium Succinate Hexahydrate in food?
A: It serves primarily as a flavor enhancer, especially to intensify umami and seafood-like tastes. It works synergistically with MSG, I+G, and other enhancers.

Q: What is the difference between the hexahydrate and anhydrous forms?
A: The hexahydrate (C₄H₄Na₂O₄·6H₂O) contains six water molecules and is the most commonly used form in food due to better handling and solubility characteristics. The anhydrous form (C₄H₄Na₂O₄) is less frequently used.

Q: How should it be stored?
A: Store in tightly closed containers in a cool, dry place away from moisture and light to prevent clumping or degradation.
