Introduction

1. Standard background and revision notes

This standard GB 1886.338-2021 "National Food Safety Standard Food Additive Trisodium Phosphate" replaces the previous version GB 25565-2010. The main modifications include:

Definition of the scope of modification
Trisodium phosphate dodecahydrate indicator is adjusted to be measured on an ignition dry basis
Test methods are optimized, such as the detection of fluorine adopts GB/T 5009.18, and the detection of lead and arsenic adopts the new standard method

2. Standard framework and comparison table

Item	Trisodium phosphate anhydrous	Trisodium phosphate monohydrate	Trisodium phosphate dodecahydrate
Molecular formula	Na₂PO₄	Na₃PO₄·H₂O	Na₃PO₄·12H₂O
Relative molecular mass	163.94	181.96	380.14

3. Interpretation of technical requirements

Sensory requirements

Trisodium phosphate should be white powder or crystals, which should be confirmed by visual inspection and touch.

Physical and chemical indicators

Including the limit requirements of phosphate content, moisture and other impurities to ensure product purity.

4. Implementation suggestions and precautions

Manufacturers need to be equipped with professional testing equipment, such as pH meters and high-temperature furnaces.
Strictly control the source of purchases to ensure the quality of raw materials
Regularly carry out employee training to grasp the changes in the new version of the standard
