Sodium Diacetate, E262 referred to as SDA, a white crystalline anhydrous molecular weight of 142.9 meters at the end, of acetic acid odor, moisture, soluble in water and alcohol, the crystal structure are hexahedral, melting point 96 ℃ -97 ℃, heated to above 150 ℃ decomposition.
Sodium Diacetate of the main features:
Mold corrosion better than acid salts, usually the amount is 0.3-3g/kg. Sodium Diacetate does not change the characteristic of the food, not food itself PH effect in the bodys metabolism, Sodium Diacetate produce CO2 and H2O, can be seen as part of the food, to maintain the original color, flavor and food nutrients. Use a wide range, Sodium Diacetate mold for various types of food preservation, but also in the pharmaceutical, tobacco, paper, fresh fruit, feed, etc. There are also a great application. Flexible operation, can also be sprayed or added directly dipping. Sour soft, propionate overcome the unique smell. Sodium Diacetate of the inhibitory mechanism of action and effects. Studies have shown, Sodium Diacetate is mainly effective penetration into the mold through the cell wall and interfere with the interaction of the enzyme, inhibiting the production of mold, so as to achieve efficient mold, corrosion and other functions, Sodium Diacetate for Aspergillus virus, black Rhizopus, Aspergillus, Trichoderma viride inhibitory effect than potassium sorbate.
Sodium Diacetate uses:
Sodium Diacetate and have a good mold, corrosion, and preservation of efficacy, but also can enhance the appetite, promote the conversion of feed absorption, increase feed protein utilization.
1, dietary Sodium Diacetate ,0.1-0 .2% 1-2 kg / tonne E262 may effectively prevent the moldy feed, feed store extended to 1-2 months; in the feed and ensilage add 0.1-0.3% Sodium Diacetate can feed preservative 3-5 months.
2, Sodium Diacetate to make nutrition a flavoring agent in the particles with 0.05-0.2% of dietary Sodium Diacetate, can feed protein utilization increased by 11%, 10% of fish weight gain, increased piglet weight gain of 6-8%, chicken, increased 6-10% by weight duck, beef cattle weight gain by 15%, 10-20% general increase in feed intake. Amount of feed in cows with added Sodium Diacetate, can effectively improve the protein content of cow milk.
3, Sodium Diacetate as a disinfectant, Sodium Diacetate in aquatic feed add 0.1-0.2% of the SDA, to be effective in prevention and treatment of fish with the original micro-organisms due to illness, Sodium Diacetate can be used for ponds to clarify the disinfectant; in poultry diets 0.05-0.3% of the Sodium Diacetate, pulled chicken can prevent dysentery, and improve brood survival rate of 10%.
