Water retention agent sodium tripolyphosphate food additive adds luster to life

With the increasing consumption power of people, food is becoming more and more colorful. Food moisture retention agent plays an important role in food industry. Sodium tripolyphosphate is one of the food additive water retention agents.


Water retention agent of food is a kind of food additive which is helpful to keep the stable water content in food. It belongs to the quality improver, mainly refers to the phosphate used in meat and aquatic products processing to enhance water stability and improve water retention. Condensed phosphates are hydrophilic substances, which can stabilize the water content in food.


Food additive sodium tripolyphosphate can improve the PH value of meat, chelate the metal ions in meat and increase the ionic strength of meat. Dissociation of some meat proteins can keep the maximum water content of meat products, improve the binding power, tenderize the meat quality and maintain more nutrients. It is an important additive for meat products, especially for minced meat, sausage, meat stuffing, etc.


Sodium tripolyphosphate is hydrolyzed in aqueous solution. The hydrolysis rate varies with the temperature and PH of the solution. The hydrolysates are pyrophosphate and right acid salt. The addition of sodium tripolyphosphate in the internal food can improve the product quality, such as regular appearance, fresh meat, bright color, etc. It can separate calcium pectinate and calcium oxalate on the surface of fruits and vegetables, and promote the softening of skin.


Water retention agent of food additive sodium tripolyphosphate adds luster to life. The water retention agent sodium tripolyphosphate produced by Chongqing Chuandong Chemical Group has stable quality and few impurities.

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
