Food Grade Sodium phosphate tribasic dodecahydrate 10101-89-0

What is Sodium Phosphate Tribasic Dodecahydrate?

Sodium phosphate tribasic dodecahydrate is a hydrate of trisodium phosphate, belonging to the category of inorganic phosphates.

Its common chemical formula is:

Na3PO4⋅12H2O

Judging from the name:

· Sodium phosphate : refers to sodium phosphate;

· Tribasic : indicates trisodium salt, meaning that all three acidic hydrogen atoms in phosphoric acid are replaced by sodium.

· Dodecahydrate : This refers to a dodecyl hydrate, meaning that the crystal contains twelve water molecules of crystallization.

Food-grade sodium phosphate tribasic dodecahydrate is usually a white crystalline, granular, or powdered substance that is readily soluble in water and whose aqueous solution is distinctly alkaline.

It has the following characteristics:

· It has good water solubility ;

· It is highly alkaline ;

· It has a buffering effect ;

· It can complex or chelate with metal ions ;

· It can improve the water retention, emulsification, and stability of food processing systems ;

· Food-grade products have stricter controls on indicators such as heavy metals, arsenic, fluorides, and insoluble matter .

Uses of food-grade Sodium Phosphate Tribasic Dodecahydrate

1. Processed foods

Food-grade sodium phosphate tribasic dodecahydrate can be used as a food additive or processing aid in certain food processing systems. Consumers may be exposed to phosphate components in some processed foods.

The food items that may be involved include:

· Meat products;

· Surimi products;

· Processed seafood products;

· dairy;

· Baked goods;

· Convenience foods;

· Seasonings;

· Compound food ingredients.

2. Meat and seafood processing

Phosphates are commonly used in meat and seafood processing, primarily to improve processing performance. Sodium phosphate tribasic dodecahydrate, due to its alkaline and ion-regulating properties, may participate in certain compound phosphate systems.

Common scenarios include:

· Ham;

· sausage;

· Luncheon meat;

· Cured meat products;

· Frozen fish fillets;

· Shrimp;

· Fish Ball;

· Fish paste products such as crab sticks.

Its functions are usually related to water retention, improving tissue structure, increasing tenderness, and stabilizing the protein system.

3. Dairy and beverage processing

In some dairy products, non-dairy creamer, milk tea powder, compound beverages, or nutritional drinks, phosphates may be used to stabilize proteins, regulate pH, or improve solubility.

Possible involvement:

· Processing cheese;

· milk powder;

· Non-dairy creamer;

· Modified milk;

· Protein drinks;

· Complex nutritional beverage.

However, the types and amounts of phosphates permitted for use vary depending on the food category, and must comply with local food additive regulations.

4. Acidity regulators

Because trisodium phosphate aqueous solution is alkaline, it can be used to adjust the pH of food systems, helping to maintain a suitable acid-base environment for processing.

pH has a significant impact on food, for example:

· Protein solubility;

· Color stability;

· Flavor profile;

· Microbial stability;

· Gel formation;

· Stability of the processing.

5. Moisture-retaining agent

In meat and seafood products, phosphates can improve the water-holding capacity of proteins and reduce moisture loss during processing and freezing.

This helps:

· Improve the taste;

· Improve tenderness;

· Reduce cooking losses;

· Maintain product form;

· Improve freezing and thawing stability.

6. Stabilizers and emulsifying aids

In dairy products, sauces, and complex protein foods, phosphates can help stabilize the system and improve the dispersion of proteins, fats, and aqueous phases.

Possible applications:

· Processing cheese;

· Emulsified meat products;

· Sauces;

· Protein drinks;

· Compound food ingredients.

7. Chelating agents and quality improvers

Sodium phosphate tribasic dodecahydrate can react with certain metal ions, reducing the adverse effects of metal ions on color, flavor, or oxidation reactions.

In food, this effect helps to:

· Improve color stability;

· Reduce oxidative deterioration;

· Improve processing consistency;

· Improve product shelf life performance.

Summarize

Sodium phosphate tribasic dodecahydrate , also known as trisodium phosphate dodecahydrate , is an important inorganic phosphate with the chemical formula:

Na3PO4·12H20

Food-grade products can be used in specific food processing applications, with common functions including acidity adjustment, moisture retention, stabilization, emulsification assistance, and chelation. However, their use must comply with local food additive regulations and maximum usage requirements.

In daily life, we may come into contact with it or related phosphates through the following routes:
