Can sodium tripolyphosphate be used as the water retainer?

Water retention agent refers to a kind of substance which can improve the stability of the product, maintain the water holding capacity of the food and improve the shape, flavor and color of the food in the process of food production and processing. In order to help maintain water content in food, substances added are usually used in meat and aquatic products processing to enhance water stability and high water holding capacity of phosphate. Sodium tripolyphosphate is one of the water retention agents.

Can sodium tripolyphosphate be used as the water retainer?

The answer is yes. Food-grade sodium triphosphate can keep the water holding capacity of meat, enhance the binding force, and maintain the nutritional composition and tenderness of meat in meat products. The mechanism of sodium tripolyphosphate improving water holding capacity of meat is as follows:
1.Sodium tripolyphosphate can increase the PH of meat and make it deviate from the isoelectric point of meat protein (PH5.5).
2.Sodium tripolyphosphate can chelate metal ions in meat, and make protein in muscle tissue chelate with calcium and magnesium ions.
3.Sodium tripolyphosphate can increase the ionic strength of meat, which is conducive to the transformation of muscle protein into loose state.
4.Sodium tripolyphosphate can dissociate actin from muscle protein.

The food grade sodium tripolyphosphate produced by Chuandong Chemical group has high purity, less impurities and more stable quality. More details of food grade sodium tripolyphosphate can be clicked to see.

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
