Sodium Diacetate

Sodium Diacetate E262 (CAS No: 126-96-5) Supplier in Europe

Sodium diacetate is a compound frequently used in various industries, especially food manufacturing. It serves a dual role as a preservative and a flavoring agent, making it invaluable in extending shelf life and enhancing the taste of products.

Its efficacy as an antimicrobial agent is particularly noteworthy, helping to inhibit the growth of pathogens such as E. coli and Listeria.

This compound is a blend of acetic acid and sodium acetate.

Its ability to lower pH levels and act as a buffering agent increases its versatility across different applications.

Consumers may not always realize it, but sodium diacetate is a key ingredient in many common foods, including baked goods, snacks, and dressings as E262.

Beyond food, sodium diacetate is also used in other sectors.

It can serve as an anti-caking agent in chemical formulations, due to its ability to absorb moisture.

This diverse range of uses underscores its importance in multiple industries.

Chemical Properties

Sodium diacetate (E262 food additive)  is a compound known for its specific molecular composition and distinct physical and chemical properties. It exhibits stable behavior under various conditions, making it valuable in a range of applications.

Composition and Structure

Sodium diacetate is composed of sodium, acetic acid, and water.

The chemical formula is C2H5NaO2

This compound combines one molecule of sodium acetate and one molecule of acetic acid through hydrogen bonding.

The structure consists of a sodium ion (Na^+) and a diacetate ion formed from two acetate ions (CH_3COO^-).

These ions interact through electrostatic forces, creating a crystalline solid.

These structural features are essential for its antimicrobial and preservative functions.

Physical Properties

Sodium diacetate appears as a white, crystalline powder. It has a molecular weight of approximately 142.09 g/mol.

This compound is hygroscopic, meaning it readily absorbs moisture from the air.

Its melting point is about 324°C, and it is highly soluble in water, exhibiting a solubility of roughly 450 g/L at 20°C.

It has a mildly acidic taste and odor, owing to the presence of acetic acid.

These physical properties are crucial for its effective use in food preservation.

Chemical Stability

Sodium diacetate is chemically stable under normal conditions. It does not react easily with other substances, making it a reliable additive in food processing.

This stability persists over a wide range of pH levels, ensuring consistency in its preservative function.

Exposure to excessive heat or moisture can cause it to decompose, releasing acetic acid.

Therefore, it should be stored in a cool, dry place to maintain its stability.

Its resistance to bacterial and fungal growth highlights its effectiveness in extending the shelf life of perishable products.

Applications

Sodium diacetate serves as a multifunctional ingredient, primarily used in the food industry, as a preservation and antimicrobial agent, and in various industrial applications to enhance product quality and shelf life.

Food Industry

In the food industry, sodium diacetate is commonly used as a flavoring agent and pH regulator.

It imparts a tangy flavor to snacks, baked goods, and sauces.

Additionally, sodium diacetate helps maintain an optimal pH balance, which can improve the taste and texture of food products.

This compound is especially popular in seasonings for chips and crackers, providing a vinegar-like flavor.

It is also used in pickling solutions to enhance acidity.

Preservation and Antimicrobial Agent

As a preservation and antimicrobial agent, sodium diacetate plays a crucial role in extending the shelf life of perishable products.

It inhibits the growth of fungi, mold, and bacteria, ensuring safety and longer shelf availability.

The effectiveness of sodium diacetate is particularly notable in bake products and cheese, where it delays spoilage.

It’s also employed in meat and poultry products to inhibit microbial growth, improving both the safety and longevity of these items.

Industrial Uses

Beyond food, sodium diacetate has important industrial applications.

In agriculture, it serves as a E262 feed additive to maintain the health of livestock by acting as an antimicrobial agent.

In addition, it finds use in pharmaceutical formulations as a buffering agent to maintain stable pH levels.

Sodium diacetate is also utilized in cleaning solutions and water treatment, where its antimicrobial properties help maintain sanitation and purity.
