Chinese name: sodium diacetate
Chinese Alias: sodium diacetate; SDA; a sodium diacetate; double sodium acetate
English name: Sodium diacetate
English Name: sodiumhydrogen diacetate
Molecular formula: C 4H7 NaO4
Molecular Weight: 142.09
Appearance: sodium diacetate sodium acetate and acetic acid molecular complexes, a white hygroscopic crystalline powder or crystalline solid with acetic acid smell, no poisonous, soluble in water and ethanol is heated to above 150 ℃ decomposition, combustible 1g present. about 1mL materials can be dissolved in water. 10% pH of the solution is 4.5 to 5.0.
Uses: Sodium diacetate is a versatile food chemicals, mainly used as antiseptics, antifungal agents, chelating agents, flavoring agents, PH adjusting agents, meat preservatives in food and feed industry, as well as composite mold The main raw material agent.
1 Dietary 0.1-0.2% 1-2 kg / tonne SDA can effectively prevent feed mildew, so feed store extended 1-2 months; in compound feed add 0.1-0.3% of SDA can feed preservative 3 -5 months.
2. as nutrition flavoring
Add feed particles in 0.05-0.2% of SDA, can feed protein utilization increased 11%, more than 10% of fish weight gain, piglet weight gain 6-8%, chicken, duck weight gain 6-10 %, 15% of beef cattle weight gain, feed intake generally 10-20% increase in the milk, add the appropriate amount of feed, can effectively improve the protein content of milk cows.
3. as a disinfectant
Add 0.1-0.2% in aquatic feed SDA, can effectively prevent homologous fish by microorganisms patients, can be used as a disinfectant clarification ponds; adding 0.05 to 0.3% of the SDA in poultry feed, can prevent chicken pull dysentery, and improve the survival rate of more than 10% of the brood.
4. Application of sodium diacetate in weaning feed
0.3% of dietary sodium diacetate make weaning ADG than the 10.8 percent increase does not add a significant difference; have a significant effect on weaning piglets added daily intake of sodium diacetate can significantly improve. weaning piglet feed conversion rate (10.5 percent increase), it may be mainly sodium diacetate improve the utilization of feed nitrogen and energy.
Packing & Storage
1. Sodium diacetate packaging plastic bags do within packaging, packaging brown paper bag, net weight is 25KG.
2. airtight storage, low temperature, moisture, sun, not with other alkaline substances and toxic mixed silage, feed additives in feed processing, high temperature should be avoided to prevent decomposition of sodium diacetate, reducing its consumption effects.
