Other names:

SODIUM DIACETATE; 126-96-5; Sodium Hydrogen Diacetate; Dykon; Acid Acetate; Acetic Acid Sodium Salt; Sodium Acid Acetate

Not to be confused with sodium acetoacetate, a salt of acetoacetic acid or diacetic acid.

Physical and Chemical Properties:

1. Sodium diacetate is an unprescribed ADI and is recognized by the FDA as GRAS.

2. Sodium diacetateis white crystal, with acetic acid odor, easy to absorb moisture, easy to dissolve in water, heated to 150℃ above decomposition, with flammability, in cool dry conditions stable property.

3. Sodium diacetate mainly depends on the decomposition of molecular acetic acid to play an antibacterial effect; SDA has a good inhibition of bacteria and mold.

Functions and features:

1. Sodium diacetate does not change the characteristics of food, is not affected by the food itself PH, participates in the metabolism of human body, produces CO2 and hydrogen peroxide, can be regarded as part of food, maintain the original color, fragrance and nutritional components of food.

2. Sodium diacetate is better than potassium sorbate in inhibiting fungi and has better anti-mildew and anti-corrosion effect than benzoates (sodium benzoate).

3. Sodium diacetate has a mild acidity and overcomes the irritating odor of propionates (calcium propionate).

Packaging & Shipping

·Packaging and Storage:

1. Sodium diacetate is packed in plastic inner bags, and woven bags/kraft bags are used for outer packing. The net weight is 25kg.

 2. Storage in sealed, low temperature, moisture-proof, sunscreen environment, do not mix with other alkaline and toxic substances.

Product Application

·Application of Sodium diacetate in animal feeds:

1. Prevent feed mildew and prolong the storage period.

2. Improve the milk protein content of dairy cows and the utilization of protein in feed to increase the weight of fish and piglets.

3. Adding SDA to poultry feed can prevent pullorum and improve the survival rate of chickens.

4. Adding SDA to aquatic feed can effectively prevent and treat fish diseases caused by homologous microorganisms and can be used as clarifying disinfectant in fish ponds.

·Application of Sodium diacetate in foods:

As food preservative, sodium diacetate is safe, non-toxic, non-residual, non-carcinogenic and non-teratogenic, it has been recognized as "0" toxic substance by WHO.

Sodium diacetate is an ideal substitute for potassium sorbate, sodium benzoate, calcium propionate and other preservatives.

1- SDA is good anti - toxic effect in cereals and cereals.

2- SDA can be used in baking foods, such as bread, cakes, etc., to prevent mildew.

3- SDA is widely used in the flavoring of puffed food because of the function of preservative, sour agent and nutritive agent.

4-When used as a compound preservative (Polylysine 0.01%, chitosan 0.80%, sodium diacetate 0.30%, EDTA 0.01%) in chilled meats, SDA will greatly extend the shelf life.

5-Adding sodium diacetate into meat products, sausage and cured meat can prevent mildew, prolong the storage period and enhance the fresh and tender effect of meat products.

6- SDA can extend the shelf life of drinks, fruit juices, jams and jellies.

7-SDA can prevent or reduce bacterial contamination in process of making pickles.
