【Product Parameters】

1. Chemical Name: SODIUM DIACETATE

2. Molecular Formula : C₄H₇NaO₄·xH₂O

3. Molecular Weight: 142.09 (Anhydride)

4. CAS: 126-96-5

5. Properties: Sodium Diacetate is in the form of white crystalline particles or powder, has the characteristic smell of acetic acid, and is prone to deliquesce. It is highly soluble in water. Every 1 gram can be completely dissolved in 1 ml of water to form an acetic acid solution with a concentration of 42.25%; the pH value of a 10% aqueous solution is stable between 4.5-5.0. When the temperature rises to 150℃, Sodium Diacetate will decompose and has flammable properties.
6. Packaging: Sodium Diacetate adopts a double-layer packaging structure, with an inner layer of polyethylene bags and an outer layer of plastic woven bags. The net weight of a single bag is 25kg, ensuring the sealing and transportation safety of the product.
7. Storage and Transportation: Sodium Diacetate should be stored in a dry, clean and well-ventilated warehouse, away from direct sunlight and high temperature environment. During transportation, strict waterproof and moisture-proof measures must be taken. Throwing and heavy pressure are strictly prohibited during loading and unloading to prevent the packaging bag from being damaged, causing product leakage or deterioration. At the same time, it must be kept away from heat sources to avoid product decomposition or safety hazards caused by high temperature.

 

 

【Product Advantages】

Stable Antibacterial Effect
Sodium diacetate inhibits the growth of mold and bacteria by releasing free acetic acid. The antibacterial efficiency is increased by more than 40% in an environment with pH < 6.0, which is suitable for high-risk categories such as meat and baked products.

 

Safer To Use
Sodium hydrogen diacetate has a purity of ≥ 99% and is non-corrosive. Unlike liquid acetic acid, it has no irritation risk to equipment and manual operation, and is suitable for automated packaging and room temperature storage and transportation.

 

Seasoning Function
Sodium hydrogen diacetate contains edible acetic acid components, which have a slight sour taste and salty freshness in meat products and sauces. It can partially replace salt and vinegar to improve flavor coordination.

 

 

【Product Application】

Meat Products Industry
Sodium diacetate can directly inhibit the growth of common spoilage microorganisms such as Listeria and lactic acid bacteria. It is often used in cooked food, pickled products and cold cuts, effectively extending the refrigeration period of products by more than 7 days.

 

Baking Industry
Sodium diacetate can significantly reduce the risk of mold reproduction. It is often used in products with high water content such as bread and cakes to maintain texture stability and extend the shelf life to avoid premature mold or deterioration.

 

Seasoning Industry
Sodium hydrogen diacetate, as a pH regulator, can maintain the stability of vinegar, sauces, and compound seasoning powder systems. It also has a slight sour taste, enhances the flavor level and inhibits the growth of harmful bacteria.

 

Pre-prepared Food Industry
Sodium hydrogen diacetate is used in Chinese pre-prepared food to control the problem of microbial back-infiltration after pickling and heating, which can significantly improve the food safety and shelf life of cold chain distribution.

【Frequently Asked Questions】

Q: What payment methods do you accept?

A: T/T, L/C, Credit Card, PayPal, Western Union, Cash.

 

Q: What payment currencies do you accept?

A: USD, EUR, RMB.

 

Q: How is the product packed?

A: The inner layer is packed in polyethylene bags and the outer layer is packed in composite plastic woven bags. The net weight of each bag is 25 kg.

 

Q: How can the product be shipped?

A: It can be shipped by truck, train, sea, and air.

 

Q: What are the characteristics of the physical and chemical properties of sodium diacetate?
A: The melting point of sodium diacetate is 96-97℃, and it decomposes above 150℃. Its aqueous solution is weakly acidic, with a pH value of about 4.5-5.0. It has good stability in the air, but it is highly hygroscopic and easy to deliquesce, so it needs to be sealed for storage.

 

Q: What is the antibacterial working principle of sodium diacetate?
A: In an acidic environment, sodium diacetate releases acetic acid molecules. Acetic acid can penetrate the cell membrane of microorganisms, interfere with the pH balance in the cell, inhibit enzyme activity, and destroy protein synthesis in the cell, thereby achieving an antibacterial and preservative effect.

 

Q: How to properly store sodium hydrogen diacetate?
A: Sodium hydrogen diacetate should be sealed and stored in a cool, dry, ventilated place, avoiding direct sunlight and humid environment. The storage temperature should be controlled below 30℃ and the humidity should be lower than 65% to prevent deliquesce and failure.

 

Q: What are the advantages of sodium hydrogen diacetate compared with other preservatives?
A: Compared with benzoic acid and its salts, sodium hydrogen diacetate has lower toxicity and a wider antibacterial spectrum; compared with potassium sorbate, it has lower cost and more stable preservative effect in foods with high moisture content.

 

Q: How is sodium hydrogen diacetate prepared?
A: Sodium hydrogen diacetate is usually prepared by reacting acetic acid with sodium carbonate or sodium hydroxide. The finished product is obtained by precisely controlling the reaction temperature, raw material ratio and reaction time, and through concentration, crystallization, drying and other processes.

 

Q: What are the incompatibility taboos when using sodium diacetate?
A: It should not be mixed with alkaline substances, otherwise a neutralization reaction will occur, reducing the preservative effect; it cannot coexist with strong oxidants to avoid chemical reactions and affect safety.
