English description（英文原文，共 1205 字符）
Product Name:Sodium Hexametaphosphate
English Name:Sodium Hexametaphosphate
CAS No.:68915-31-1
Aliases:Graham's Salt, Sodium Polymetaphosphate, Hexasodium Metaphosphate
Molecular Formula:(NaPO3)6
Physical Properties:Colorless transparent glassy flakes or free-flowing crystalline powder, hygroscopic. Density approx. 2.484 g/cm³, decomposes at approx. 628°C. Readily soluble in water, insoluble in organic solvents such as ethanol; aqueous solution is weakly alkaline.
Uses:Used as a quality improver, pH regulator, metal ion chelating agent, binder and swelling agent in the food industry. It stabilizes natural pigments in beans, canned fruits and vegetables, and sweetened bean paste to protect food color. In canned meat and meat products, it emulsifies fat, maintains uniform texture, improves water-holding capacity and prevents fat rancidity. It also clarifies beer and prevents turbidity, and serves as an excellent scale-free water softener.
Technical Specifications:
Content of general phosphates (as P2O5) ≥ 68.0%
Content of inactive phosphates (as P2O5) ≤ 7.5%
Water insolubles ≤ 0.06%
pH value (1% aqueous solution) 5.8-6.5
Heavy metals (as Pb) ≤ 0.001%, arsenic (as As) ≤ 0.0003%
