Characteristics of sodium acetate
Apr 24, 2021
Sodium formate (English Name: sodium formate; Formal acid sodium salt, also known as sodium formic acid, contains two crystal water in the crystal, so it is also known as sodium formate dihydrate, sodium formate dihydrate and sodium formate hydrate. Sodium formate is one of the simplest organic carboxylate, which is white crystal or powder with a slight smell of formic acid. Slightly deliquescent and hygroscopic. It is soluble in about 1.3 phr water and glycerol, slightly soluble in ethanol and octanol, and insoluble in ether. Its aqueous solution is alkaline. When heated, sodium formate decomposes into hydrogen and sodium oxalate, and then forms sodium carbonate. Sodium formate is mainly used in the production of sodium formate, oxalic acid and formic acid. In leather industry, it is used as camouflage acid in chrome tanning process, catalyst and stabilizer, reducing agent in printing and dyeing industry. Sodium formate is harmless to human body and irritates eyes, respiratory system and skin. The molecular formula is cho2na and the chemical structure formula is hcoona and hcoona · 2H2O[ 1-2]
With the recent two years, China's chemical industry manufacturers such as sodium acetate strict control, whether from the mode of production or use process, products with strong environmental pollution, have varying degrees of control. On the contrary, we encourage and support the use of sodium acetate and other products that have little impact on the environment, so as to make it more widely used. Therefore, we will introduce the advantages of sodium acetate in detail.
Sodium acetate
1. Widely used
Sodium acetate is suitable for all kinds of food crops, all kinds of food, feed, fruit, vegetables, meat, egg food, etc. It can not only restrain the mildew of feed, but also enhance the palatability of livestock and poultry to feed, improve feed utilization rate, increase milk yield of dairy cows, milk fat rate, lean meat rate of fattening pigs and litter rate of sows; For grains with high moisture content, only spraying 0.02% sodium diacetate solution can prolong the storage period of grains for about four months; When added to food, it can not only prevent mildew and keep fresh, but also increase the flavor of food.
2. Nutrient property
The unique characteristic of SDA is that sodium acetate can increase the nutrient value of feed. In animal production, increasing sodium acetate feed can reduce feed to meat ratio, improve lean meat rate and milk fat rate of pigs, and then improve feed reward. SDA can improve the utilization rate of protein in forage silage.
3. Palatability
In food, sodium acetate can not only act as preservative, but also as chelating agent, which can prolong the shelf life of food; Improve and maintain food flavor together. The sour taste of sodium acetate in feed conceals the uncomfortable smell of increased component drugs and various trace elements, which makes many livestock prefer to eat mixed feed containing SDA, and then improve feed intake and daily gain, greatly improving the input-output ratio.
4. The price is low
The contents of acetic acid and sodium acetate in sodium diacetate were only decreased by 0.32% and 1.38% when it was stored in a cool and dry place for one year. Although its antibacterial effect is half of that of potassium sorbate, its price is one fourth of that of potassium sorbate.
5. High efficiency
Adding 0.15% ～ 0.75% SDA solution to newly harvested grain or forage can effectively prevent mildew. The antiseptic effect of SDA is better than that of propionate and sorbic acid, which are widely used now. However, the increase of SDA is lower than that of propionate, but its price is only 2 / 3 of propionate.
6. No risk
The LD50 of sodium acetate was 3.31g/kg; The LD50 of rats was 4.96g/kg; ADI was 0-15mg / kg per person per day. The final metabolites of SDA in the body are carbon dioxide and water, no residue, no toxic and side effects, no carcinogenic and pathogenic factors; A moderate intake of acetic acid is also beneficial to human and animal health, and it is listed as a nutrient type anti mildew preservative used in food and feed in the world. Therefore, SDA is a kind of environment-friendly product, which will be the best choice for food, grain and feed fungicides.
