Function of sodium diacetate
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 150ºC 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.
4. 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.
5. Sodium diacetate is better than potassium sorbate in inhibiting fungi and has better anti-mildew and anti-corrosion effect than benzoates (sodium benzoate).
6. Sodium diacetate has a mild acidity and overcomes the irritating odor of propionates (calcium propionate).
Application of sodium diacetate:
Sodium diactate,as a kind of preservative,is widely used in grain,food and feed industry.
1)Grain Preservatives SDA plays an important role in reducing grain to rot.
2)Food Preservatives SDA is the ideal substitute of Potassium Sorbet,Sodium Benzoate,Calcium Propionate,etc,widely used in processed food industry.
3)Feed Preservatives SDA and complex as fodder chemical fungicide, also is a kind of high efficient, safe, low cost preservatives,apply to all mouldprood and preservation of plant mixed feed and raw materials.
4)Used in breeding animals as Nutrient Additives
