Tri sodium phosphate CAS number is one of the 7601-54-9, English is in this report phosphate, trisodium phosphate can be regarded as to phosphoric acid as matrix, with three atom Na Na, the total replacement of the IT formula contains three hydrogen ions (H +, the product obtained. Because phosphoric acid H3PO4 is three yuan acid, its molecular formula has 3 hydrogen ion can be replaced by metal elements.

Application area:
1 the work of improving the quality of the metal ions, pH value, increase the role of ionic strength, and thus improve the food and water retention of the knot. China regulations can be used for cheese, the largest use of 5g/kg; in western ham, meat, fish, shrimp and crab in the maximum use of 3.0g/kg; in canned, fruit juice, beverage and dairy products in the maximum use of 0.5g/kg.
2. And in the chemical, textile, printing and dyeing, paper making, power and other industries as soft water and detergents, boiler antiscaling agent, dyeing paper softening agent, production of glossy paper with adhesive pH buffer, dye fixing agent, weave mercerized enhancer, wire anti brittle agent. Metallurgical industry used for chemical cleaning, decontamination, used as excellent photographic solution in accelerator. Detergent for tooth cleaning aent and bottle opener. Rubber latex coagulant. Syrup purification agent. Phosphate plays a role in improving theg quality of food processing, for example, in meat products have the ability to maintain the meat of the meat, improve the effect of the knot, in order to reduce the loss of nutrients in meat and preserve the meat tenderness. In food processing, also used as emulsifier, nutritional supplements, quality improvement agent. Is prepared with alkali raw materials used in the manufacture of pasta, also sugar refining and alpha starch. Also used as food bottles, cans and other detergents.
3. And solid phosphoric acid sodium (TSP) belongs to the strong base weak acid salt, has a strong alkaline and high solubility, chemical stability to long-term preservation, in the containment spray system (EAS) spray water added TSP substitute NaOH, can adjust the spray liquid pH value, effectively removed from the iodine gas leakage of cooling water release to secure shell, to avoid damage of alkali on the staff, easy accident after the clean-up.
Sodium pyrophosphate,Molecular Na4P2O7 and 10H2O, relative molecular mass 446.07. Also known as two phosphoric acid four sodium, there is no water and ten of the water content of the. Ten water is colorless or white crystal or crystalline powder, water is white powder, soluble in water, insoluble in ethanol and other organic solvents. And Cu2+, Fe, Mn2+ and other metal ion complexing ability, the water solution is stable at 70 degrees Celsius, boiling is hydrolyzed to two sodium hydrogen phosphate.

Material introduction:
Phosphoric acid four sodium; anhydrous sodium phosphate; ten sodium phosphate
Appearance: white powder or crystal
Chemical formula: Na4P2O7
Molecular weight: 265.9
No. CAS: 7722 -88-5
No. EINECS: 231-767-1
H.S CODE:28353990

Physical and chemical properties:
White powder or crystal. Relative density 2.534, melting point 880, boiling point 938. Colorless transparent crystal or white crystalline powder. Soluble in water, the solubility of 100g in water at 20 degrees C is 6.23, its aqueous solution is alkaline; insoluble in alcohol. The aqueous solution is stable at 70 degrees Celsius, and boiled is hydrolyzed to two sodium hydrogen phosphate. In dry air, the loss of crystal water at a temperature of 100. In the air easy to absorb moisture and moisture. With alkaline earth metal ions can generate complex; meet with Ag+ to generate white silver pyrophosphate.
Complexation reaction with metal ions. The pH value of the aqueous solution of 1% is 10.0-10.2. It has common polymeric phosphate connectivity, emulsification, dispersion, prevent lipid oxidation and enhances protein nodes, and it can also inhibit the oxidation of food and fermentation at high pH value

Preparation method:
Sodium hydrogen phosphate was prepared by two sodium phosphate solution with anhydrous hydrogen phosphate two, and then the high temperature dehydration polymerization was obtained. One step and two steps of two, drying and polymerization in one device is done by calling one step, drying and polymerization in the two device to complete the call two steps. One step process is simple, the process is short, but the quality is not very stable. Two - step equipment is more complex, longer process, product quality is more stable, the food industry with sodium phosphate more use of two - step method. Reaction type:

(1) Sibao duck, mushrooms duck wings and mushrooms stewed ducks and other poultry, canned food, in the heating process easy to release hydrogen sulfide, hydrogen sulfide and tank iron ions generated black iron sulfide, affecting product quality. The addition of compound phosphate has a good effect on chelating metal ions, which can improve the quality of the finished product.
(2) canned pork sausage, add compound phosphate (sodium phosphate 60%, sodium salt 40%) in chopped meat.
(3) for foreign fish surimi products, compound phosphate (sodium pyrophosphate, sodium tripolyphosphate, 60% 40%).
(4) can be used as a cheese melting agent, emulsifier, can make the cheese casein calcium release calcium ions, so that the viscosity of casein is increased, to get a soft, rich in the extension of the product. General is the sodium phosphate, phosphate and partial phosphate, such as composite use, the amount of not more than 0.9% (in P).
(5) for soy sauce, bean paste, the amount was about 0.005%~0.3%, which can prevent the browning of soybean paste, improve color.
