Trisodium Phosphate Anhydrous food grade food additive

Trisodium phosphate

Chinese name: Trisodium phosphate

Foreign name: trisodium phosphate anhydrous

Chemical formula: Na3PO4·12H2O or Na3PO4

When the crystals of trisodium phosphate dodecahydrate loses twelve crystal waters at 100 ° C, they become anhydrate (Na3PO4).

Executive Standard: HG/T2517-2009

1. Appearance white or yellowish crystal.

2. The chemical composition of industrial trisodium phosphate should meet the following requirements.

Application field

• The quality improving agent of the work has the effects of improving the complex metal ions of the food, the pH value, and increasing the ionic strength, thereby improving the cohesiveness and water holding capacity of the food. China regulations can be used for cheese, large use 5g / kg; in Western ham, meat, fish, shrimp and crab. Large use of 3.0g / kg; in cans, juice, beverages and dairy products. Large use It is 0.5g/kg.

• Used as softener and detergent in boiler, chemical, textile, printing and dyeing, papermaking, power generation, boiler anti-scaling agent, soft water agent in paper dyeing, pH-based buffer for producing Adhesive for wax paper, printing and dyeing Fixing agent, mercerizing enhancer for fabric, anti-brittle agent for line making. The metallurgical industry is used as a chemical degreasing, decontamination, and as an excellent accelerator in photographic developing solutions. Detergent for tooth cleaners and bottlers. A coagulant for rubber latex. Sugar juice purifier. Phosphate plays a role in quality improvement in food processing. For example, in meat products, it maintains the water holding capacity of the meat and enhances the binding force to reduce the loss of nutrients in the meat and preserve the tenderness of the meat. It is also used as an emulsifier, a nutritional supplement, and a quality improver in food processing. It is a raw material for the preparation of edible alkali water, and is also used for the manufacture of sugar and the production of α-starch. It is also used as a detergent for food Bottles, cans, and the like.

• Solid trisodium phosphate (TSP) is a strong base weak acid salt with strong alkalinity and high solubility. It is chemically stable and can be stored for a long time. It is added in the spray water of the safe shell spray system (EAS). Instead of NaOH, TSP can adjust the pH of the spray solution, effectively remove the iodine gas released from the leaked cooling water to the containment, avoiding the damage of the strong alkali to the staff, and easy to clean after the accident.

Store in a cool, ventilated warehouse. Keep away from fire and heat. The package is sealed and must not be in contact with air. Moisture-proof and sun-proof. It should be stored separately from acids and the like. It should be lightly loaded and unloaded during handling to prevent damage to packaging and containers. The warranty period is 24 months.
