Why is the unit price of food grade sodium tripolyphosphate higher than that of industrial grade?

 Recently, the shortage of spot goods has intensified, which has entangled downstream manufacturers who want to purchase recently. Either they have not found a suitable manufacturer, or the price is not too expensive. Sodium tripolyphosphate, as a basic chemical material and related phosphorus containing products, plays an important role, and the relative price has also increased. Why is the unit price of food grade sodium tripolyphosphate higher than that of industrial grade?


First of all, it can be seen literally that the content and related indicators of industrial grade sodium tripolyphosphate meet the national standard. The main raw material of sodium tripolyphosphate is phosphate rock. In the production process, the price of wet process is slightly lower, while the sodium tripolyphosphate produced by thermal process is relatively higher.


The raw material of food grade sodium tripolyphosphate is based on the thermal process. As a food additive, it is standardized and standardized in food processing. The production of food grade sodium tripolyphosphate ensures safety in the long process from raw material production to transportation to sales to consumption.


The industrial application of sodium tripolyphosphate has the functions of chelation, suspension, evacuation, gelling, emulsification and pH buffer. It can be used as an important assistant for synthetic detergent, industrial water softener, tanning pretanning agent, dyeing assistant, organic synthetic catalyst, evacuation agent for pharmaceutical industry, etc. Sodium tripolyphosphate of Chuandong Chemical Group plays an important role in ceramic production.


Food safety is a major event. As food additive, sodium tripolyphosphate can also be used in milk and dairy products, frozen drinks, nuts, cocoa and chocolate products, wheat flour and its products, cooked meat products, baked food, expanded food, canned aquatic products, etc.


It can be seen that there is an essential difference between industrial grade and food grade sodium tripolyphosphate. Food grade can be used for industrial purposes, while industrial grade sodium tripolyphosphate must not be used for food purposes. Because there are no requirements for heavy metals such as arsenic and lead in the industrial grade product indicators, the unit price of food grade sodium tripolyphosphate is higher than that of industrial grade.

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
