Can food additive sodium tripolyphosphate retain water and improve meat quality in aquatic products processing?

 Aquatic products need water retention, which is a little different from other products. Sometimes when water is retained, it will be consumed greatly after cooked processing or thawing. As we all know, once the water loss of aquatic products has a great impact on the taste, the product has slag, has no original taste, and the color is very bad. When food additive sodium tripolyphosphate is used in aquatic products processing, can it still keep water and improve meat quality without color loss?


Sodium tripolyphosphate is mainly used in aquatic products processing to keep water in food during food processing, which can improve the color, flavor, morphology, anti-oxidation and water retention of food. For the production and processing of shrimp, sodium tripolyphosphate is used in the soaking process. It is soaked in aqueous solution for more than 1 hour, and the standard is 1PPM. The finished product will not exceed the standard.


The advantages of sodium tripolyphosphate for aquatic products processing are:

1. Fast dissolution and strong permeability.

2. Keep water and increase weight, reduce the loss of nutrients in the processing process, and improve the product yield.

3. Dissociate actin, prevent meat oxidation, increase the ionic strength of meat, keep fresh and protect color, significantly improve the quality, shape and flavor of food, and protect the fresh and tender taste of products.

4. Inhibit the growth of microorganisms, improve the stability and water holding capacity of products, and prolong the fresh-keeping and storage period of products.


With the development of economy and the improvement of residents' material living standards, consumers' demand for aquatic products has changed from single output to quality and output. Ice wet refrigeration, micro freezing refrigeration, rapid freezing preservation and cold sea water preservation technology will be gradually and widely used in aquatic products industry. Therefore, the food additive sodium tripolyphosphate as water retaining agent is also widely used in aquatic products processing enterprises, and gradually began to carry out intensive processing, promoting the optimization and upgrading of the industrial structure of aquatic products.

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
