Food Additive White TSPP Sodium Tripolyphosphate Anhydrous CAS 7722 88 5
Food Additive White 96.5% Min TSPP Sodium Tripolyphosphate Anhydrous CAS No.: 7722 88 5
Properties
White powder or crystal. The relative density is 2.534 and the melting point is 980 ℃. Colorless transparent crystal or white crystalline powder. It is easily soluble in water. At 20 ℃, the solubility of 100g water is 6.23g, and its aqueous solution is alkaline; Insoluble in alcohol. The aqueous solution is still stable below 70 ℃, and it is hydrolyzed to disodium hydrogen phosphate when boiled. It is easy to absorb moisture and deliquesce in the air. It can form complex with alkaline earth metal ions; White silver pyrophosphate is generated when it meets Ag +. Sodium pyrophosphate, with chemical formula of Na4P2O7, is a white crystalline powder, which is easy to absorb water and deliquesce in air, soluble in water, insoluble in ethanol and other organic solvents. It has strong complexation ability with Cu2 +, Fe3 +, Mn2 + and other metal ions. The aqueous solution is stable below 70 ℃, and it is hydrolyzed to disodium hydrogen phosphate when boiled
Application
It is used as quality improver, emulsifier, buffer and chelating agent in food industry. For lunch meat, sausage and other canned meat, it can improve the water holding capacity of meat products, reduce the loss of nutrients, improve the tenderness of meat, and improve the quality of finished products; As a melting agent of drying agent, emulsifier can release calcium from calcium caseinate in cheese, increase the viscosity of casein, and obtain soft and extensible products. For soy sauce and soybean paste processing, it can prevent browning, improve color, inhibit rancidity and fermentation of soybean milk; It can be used in juice, cool drink and cold drink processing to prevent oxidation and precipitation during storage; When used in ice cream processing, it has the effect of increasing its volume and emulsifying and dispersing.
Preparation method
Anhydrous disodium hydrogen phosphate is prepared by drying disodium hydrogen phosphate aqueous solution, and then dehydrated and polymerized at high temperature. It can be divided into one-step method and two-step method. One step method is used to dry and polymerize in one equipment, and two-step method is used to dry and polymerize in two equipment. The equipment of one-step process is simple, the process is short, but the quality is not stable. The two-step process has the advantages of complex equipment, long process and stable product quality. The reaction equation is as follows
Na2HP04·12H20→Na2HP04+12H20
2Na2HP04→NaP207+H20
