TetraSodium Pyrophoshapte
TetraSodium Pyrophoshapte or TSPP is a colorless inorganic salt or transparent, odorless crystal, with the chemical formula Na4P2O7, molecular weight 266 grams/mol.
In addition, TSPP also exists in a state containing 10 water molecules. TSPP is a salt that is slightly stronger than table salt and is non-flammable.
To create TetraSodium PyroPhosphate TSPP salt, H3PO4 reacts with Na2CO3, the resulting sodium phosphate is heated at 450oC. In addition, TetraSodium PyroPhosphate TSPP salt can also be produced by condensing Na2HPO4 .12H2O.

Physicochemical properties of TetraSodium Pyrophosphate
Physical properties
TetraSodium Pyrophosphate (TSPP) is a chemical compound with the formula Na ₄ P ₂ O ₇. This is a sodium salt of pyrophosphoric acid. Physical properties of TSPP include:
- TSPP is soluble in water, creating an alkaline solution.
- TSPP can absorb water from the air, so it should be stored in a dry place.
- For TSPP, melting temperature is not an important property, as it is usually used in powder or granule form.
Chemical properties
Tetrasodium Pyrophosphate (TSPP) also has specific chemical properties:
- TSPP is an alkaline salt, which means it can interact with acids to create an alkaline solution.
- TSPP can react with acids to produce pyrophosphoric acid and sodium salt, respectively.
- Able to form complexes with metal ions, especially calcium ions. This reduces water hardness and can be used in anti-scale applications.
- TSPP can interact with some metals to form complexes.
TetraSodium PyroPhosphate TSPP trong thực phẩm đóng một vai trò quan trọng trong việc ổn định hương vị và trạng thái của thực phẩm. Nó duy trì và ổn định độ pH cho thực phẩm, hạn chế sự thay đổi pH sản phẩm trong suốt quá trình chế biến.
Nó cũng là một chất phân tán, trợ phân tán các thành phần trong sản phẩm, đôi khi các thành phần này là không thể tự hòa trộn vào nhau và nằm ở 2 pha khác biệt nhưng nhờ vào tác dụng của TSPP mà tạo nên được sự đồng nhất trong thành phần cho sản phẩm, loại bỏ sự tách lớp.
Các mặt hàng hay sử dụng phụ gia này như kẹo dẻo, cốm phồng, các loại thức ăn nhanh, sản phẩm giả thịt, sản phẩm giả cua, đậu hũ…
Trong nha khoa, đặc biệt là kem đánh răng, TetraSodium PyroPhosphate TSPP được sử dụng như một trung tâm nhận biết và loại bỏ canxi và magiê từ nước bọt ở khoang miệng, làm cho 2 thành phần này không tiếp xúc và tồn tại trên răng, tác dụng làm giảm mảng bám trên răng giúp hạn chế các khả năng gây nên các bệnh về răng miệng
