The factory tells you the principle of sodium hexametaphosphate in food processing

 Phosphorus is an essential element of life. It exists in many forms in the body, but the common form is phosphate. Phosphate is a molecule consisting of phosphorus and oxygen (PO43-), which is added to various foods like salt. Phosphate can be used as preservative, thickener and starter. Sodium hexametaphosphate is a kind of food additive which is widely used in food processing.


In the past, because illegal additives have cast a great shadow on food additives, Chuandong Chemical today gives you a correct understanding of the role of sodium hexametaphosphate in food processing.


1. Sealing of metal ions

Sodium hexametaphosphate can chelate with metal ions Ca2+, Mg2+, Cu2+, Fe2+ in solution to form soluble chelates, which can prevent food from discoloration and spoilage, prevent or delay the oxidation of unsaturated fat, inhibit the growth of microorganisms and play a role of antisepsis and bacteriostasis.


2. Emulsification and Dispersion

Sodium hexametaphosphate can disperse or stabilize the incompatible substances in water to prevent the adhesion and condensation of suspension, such as emulsification of fat and protein.


3. Buffering effect

Sodium hexametaphosphate can effectively stabilize the liquid phase in the medium within a certain range of PH value, which can make food taste more delicious, so it is widely used as a food regulator.


4. Protein Action

Food grade sodium hexametaphosphate can enhance protein and glue globulin, so it can increase water and water retention of meat products, improve water penetration, promote the softening of food and improve the quality of food, and maintain the good flavor of food.


Manufacturers producing food additives need to pass a series of food safety certifications before they can be put into production. Chongqing Chuandong Chemical Group is a manufacturer with food additive production license. The food grade sodium hexametaphosphate is produced by using thermal-process food grade phosphoric acid and soda ash. It has less heavy metal content.

What role will industrial grade sodium hexametaphosphate manufacturers play in the future coating industry?

图片
The keyword in 2019 is environmental protection and safety. In 2020, environmental protection and safety hurricanes will be more violent. In the manufacturing industry, whether it's packaging, printing, furniture, shipping industry or the phosphate raw material manufacturing enterprises like Chongqing Chuandong Chemical Group that produce  industrial grade sodium hexametaphosphate , it's a good choice to withstand the environmental storm and the obvious environmental protection conditions of the enterprise itself. Take the paint industry for example, the current paint market can be found that although the domestic paint industry has achieved rapid development and formed a certain industry scale, but in the domestic high-end paint market, the domestic paint brands or enterprises are indeed few, and the domestic high-end paint market is still occupied by most of the market share of imported brands. In fact, all industries need to use coatings, and environmental protection coating

What is the use of calcium formate industrial grade in construction? The manufacturer tells you

  With the development of the city's economy, the construction of highways, bridges, tunnels, and civil construction projects will require stricter use of early strength agents. Especially in winter, in order to improve the construction period, the cement mortar needs to be raised as soon as possible and put into use.   Calcium formate industrial grade   is a good early strength agent. Although both calcium formate and calcium chloride are calcium salts, relatively speaking, the performance of calcium formate is more stable. Because the formic acid in calcium formate is a weak acid. The solution will be weakly alkaline during the hydrolysis in the aqueous solution. It can be widely used in mortar. Calcium formate industrial grade is now a newly developed low temperature early strength accelerator in China, which has been widely used in various construction cement mortars. The earliest known and used chlorine salt early strength agent in construction, but the chloride salt early str

The effect of calcium supplement with feed grade calcium formate is good when crops are short of calcium

  Is it true that crops also need calcium supplements? it is true. Crops are plants, like humans and animals, that need rich trace elements to help them grow. When crops are calcium-deficient, plant growth is hindered, and the internodes are shorter, so they are generally shorter than normal plants and have soft tissues. Since calcium has such a big effect, is it good to use   feed grade calcium formate   to supplement calcium? The meristems such as the apical buds, lateral buds, and root tips of crops with calcium-deficient plants first appear nutrient deficiency, which is perishable, the young leaves are curled and deformed, and the leaf edges begin to turn yellow and become necrotic. For example, calcium deficiency can cause leaf scorch disease in cabbage, cabbage and lettuce; tomato, pepper, watermelon, etc. have heart rot; apples have bitter pox and water heart disease. No matter how much is useless, the crops are short of calcium. If we want to achieve the actual effect, what sho
