Potassium Metaphosphate in Food

Molecular Formula：(KPO₃)n

CAS NO.: 7990-53-6

EINECS NO.: 232-212-6

Potassium Metaphosphate (KPO3) is a white crystalline powder that is used in the production of ceramics, glass, and fertilizers. It is also used as a food additive and as a component in some dental cements. Potassium metaphosphate is a source of phosphorus and potassium, two essential nutrients for plant growth. It is typically produced by heating potassium dihydrogen phosphate (KH2PO4) to high temperatures, causing it to lose water and form the metaphosphate. Potassium metaphosphate is considered safe for use in food and dental applications, but excessive ingestion or inhalation can cause irritation to the respiratory system.

Potassium metaphosphate (MKP) is a food additive that is commonly used as a buffering agent, emulsifier, and stabilizer in food products. It is a white, odorless powder that is soluble in water and has a pH of 6-8.

MKP is commonly used in the food industry to improve the texture, flavor, and appearance of food products. It is used in processed meats, dairy products, baked goods, and beverages. In processed meats, MKP is used to improve the texture and prevent the formation of a gel-like substance. In dairy products, it is used to prevent the separation of solids and liquids and to improve the texture. In baked goods, it is used to improve the texture and to increase shelf life.

MKP is generally recognized as safe by the US Food and Drug Administration (FDA) and is approved for use in food products. However, excessive consumption of MKP can lead to health problems such as kidney damage, high blood pressure, and electrolyte imbalances. Therefore, it is important to consume MKP in moderation and to follow the recommended daily intake levels.
