Details:

Sodium Diacetate a molecular compound of acetic acid and Sodium Acetate. It is white hygroscopic crystalline solid with Acetic acid smelly. It decomposes when heated to 150℃ and is combustible.

Sodium diacetate is a compound with formula NaH(C2H3O2). It is a salt of acetic acid. It is a colorless solid that is used in seasonings and as an antimicrobial agent.

Application:

According to a patent, free acetic acid is built into the crystal lattice of neutral Sodium Acetate. The acid is firmly held as is evident from the negligible odor of the product. In solution it is split off into its constituents acetic acid and Sodium Acetate.

As a buffering agent, Sodium Diacetate is applied in meat products to control their acidity. Apart from that, Sodium Diacetate inhibits the growth of various microorganisms usually found in meat products, thus it can be used as a preservative and safeguard for food safety and shelf life extension. Moreover, Sodium Diacetate can be used as a flavoring agent, applied as a powdered seasoning, to impart a vinegar taste to meat products.

1. As a preservative

Feed add 1-2 kg/ton SDA 0.1 0.2% which can effectively prevent feed mildew, extend the shelf life of feed 1-2 months; 0.1-0.3% of the SDA is added in the compound feed can make feed antisepsis for 3 to 5 months.

2. As a nutritional seasoning

In granular compound feed add 0.05 to 0.2% of SDA, can make the protein utilization ratio increased by 11% in the feed, fish weight more than 10%, piglet weight increase of 6-8%. Adding in the milk feed, can effectively improve the cow milk protein content.

3. As a disinfectant

Add 0.1 to 0.2% of SDA in aquatic feed, can effectively control the same fish patients caused by microorganisms. It can be used in fish ponds as clarifier and disinfectant. Adding 0.05-0.3% of the SDA in the poultry feed, can control the chicken pull dysentery, and enhance the survival rate of the brood period of more than 10%.

4. The application of double sodium acetate in the weaned piglets feed

Adding 0.3% of double sodium acetate in fodder to weaning piglets weight than don't add up 10.8% with significant difference. For weanling piglets daily feed intake have a significant impact. Add weaning piglets of double sodium acetate can obviously improve the feed conversion rate (10.5%), may be largely of double sodium acetate can improve the feed utilization rate of nitrogen and energy.
