Can sodium pyrophosphate also be used as a food additive? The manufacturer tells you

Food additives have been widely used in daily life. Under the condition of not exceeding the scope and quantity of use, food additives bring more high-quality choices for life. In many food ingredients, we can see the figure of food grade sodium pyrophosphate. Can we buy sodium pyrophosphate as food additive? The manufacturer tells you.


Sodium pyrophosphate, also known as tetrasodium phosphate, is divided into anhydrous and decahydrate. Decahydrate is colorless or white crystalline or crystalline powder, anhydrous is white powder, soluble in water, insoluble in ethanol and other organic solvents. The complex ability with Cu2+, Fe2+, Mn2+ and other metal ions is strong. The aqueous solution is stable below 70 ℃, and hydrolyzed to disodium hydrogen phosphate when boiling.


In the food industry, sodium hexametaphosphate, sodium pyrophosphate and sodium tripolyphosphate, as food quality improvers, have the functions of pH regulator, metal ion chelating agent, emulsifying dispersant and adhesive. Sodium pyrophosphate can also be divided into industrial grade and food grade. For example, the food grade sodium pyrophosphate with food additive production license of Chongqing Chuandong Chemical Group can be used as food additive.


Food grade sodium pyrophosphate is a kind of white powder, which can be fused when encountering water. It is used as a stabilizer and buffer in food processing. Food grade sodium pyrophosphate will be used in the production of soy sauce and juice. Food grade sodium pyrophosphate can improve the color of soy sauce and juice, making the color more bright.


Sodium pyrophosphate also has the function of softening water and dissolving insoluble salts of calcium and magnesium. It can be used in meat and aquatic products processing. It can improve water holding capacity, make meat fresh and tender, stabilize natural pigments, prevent fat corruption. In addition, it can also be used in yeast powder, cheese manufacturing, etc.


Food grade sodium pyrophosphate can also be used in starch manufacturing, etc., and is often used in combination with other condensed phosphates. Sodium pyrophosphate is generally added 0.5-3 ‰ in food processing, and the maximum amount of sodium pyrophosphate is 3% in aquatic products processing.

The manufacturer tells you the dispersing effect of sodium hexametaphosphate

The dispersing effect of sodium hexametaphosphate is due to its hydrolyzed anions adsorbed on the particle surface. In order to improve the dispersing effect, the hydrolysis degree of the dispersant can be selectively increased. It is believed that we all know that the function of dispersant is to increase the distance between the large particles to be dispersed in the solution and reduce the viscosity of the whole solution. However, the amount of   sodium hexametaphosphate   used in the dispersion of different substances is also different. In the process of material dispersion, the surface of large particles adsorbs the dispersant to form a double electric layer, and anions are closely adsorbed on the surface of particles, which is called surface ions. Ions with opposite charges in the medium are called anti ions. In the process of medium movement, particles and particles, as well as the electric double layer and the electric double layer have the same charge, which will generate elec

Non-antibiotic growth promoter potassium diformate helps pig industry return to its essence

  The high profitability of the pig industry will not last, and the future development of the industry still needs to return to the essence of pig raising. The non-antibiotic growth-promoting agent   potassium diformate  helps return to the essence of breeding and helps control the cost and quality of the pig industry. Biosecurity has become the access condition of today's pig industry. Potassium diformate has the following functions and functions to return the essence of pig farming to the breeding industry: (1) Adjust the palatability of feed and increase animal feed intake. (2) Improve the environment of the animal's digestive tract and lower the pH of the stomach and small intestine. (3) It has anti-bacterial and growth-promoting effects. The addition of potassium diformate can significantly reduce the content of anaerobic bacteria, Lactobacillus, Escherichia coli and Salmonella in each segment of the digestive tract. Improve the resistance of animals to diseases and reduce

The factory tells you food grade sodium tripolyphosphate/STPP requires heavy metal purification

Condiments, meat products, edible oil, dairy products, drinks, etc. are all necessities of daily life. Some food additives will be used in the production and processing process. The use of additives also makes people more concerned about "safety on the tip of the tongue".  Sodium tripolyphosphate/STPP  is widely used in food additives. Chongqing Chuandong Chemical Group will show you the main applications of sodium tripolyphosphate/STPP in the food industry: 1. Food grade sodium tripolyphosphate is used in meat products, fish sausage, ham, etc., which can improve the water holding capacity, increase the cohesiveness and prevent fat oxidation; 2. For fruit drinks and cool drinks, it can improve the juice yield, increase the viscosity and inhibit the decomposition of vitamin C. 3. It can prevent discoloration, increase viscosity, shorten fermentation period and adjust taste when used in soybean paste and soy sauce. 4. For ice cream, it can improve the expansion capacity, increa
