Food additives have been widely used in daily life. Under the condition of not exceeding the scope and quantity of use, food additives bring more high-quality choices for life. In many food ingredients, we can see the figure of food grade sodium pyrophosphate. Sodium pyrophosphate can also be used as a food additive.

Sodium pyrophosphate, also known as tetrasodium phosphate, is divided into anhydrous and decahydrate. Decahydrate is colorless or white crystalline or crystalline powder, anhydrous is white powder, soluble in water, insoluble in ethanol and other organic solvents. The complex ability with Cu²⁺, Fe²⁺, Mn²⁺ and other metal ions is strong. The aqueous solution is stable below 70 ℃, and hydrolyzed to disodium hydrogen phosphate when boiling.

In the food industry, sodium hexametaphosphate, sodium pyrophosphate and sodium tripolyphosphate, as food quality improvers, have the functions of pH regulator, metal ion chelating agent, emulsifying dispersant and adhesive. Sodium pyrophosphate can also be divided into industrial grade and food grade. For example, the food grade sodium pyrophosphate with food additive production license of Chuandong chemical group can be used as food additive.

Food grade sodium pyrophosphate is a kind of white powder, which can be fused when encountering water. It is used as a stabilizer and buffer in food processing. Food grade sodium pyrophosphate will be used in the production of soy sauce and juice. Food grade sodium pyrophosphate can improve the color of soy sauce and juice, making the color more bright.

Sodium pyrophosphate also has the function of softening water and dissolving insoluble salts of calcium and magnesium. It can be used in meat and aquatic products processing. It can improve water holding capacity, make meat fresh and tender, stabilize natural pigments, prevent fat corruption. In addition, it can also be used in yeast powder, cheese manufacturing, etc.

Food grade sodium pyrophosphate can also be used in starch manufacturing, etc., and is often used in combination with other condensed phosphates. Sodium pyrophosphate is generally added 0.5-3 ‰ in food processing, and the maximum amount of sodium pyrophosphate is 3% in aquatic products processing.
