Calcium polyphosphate

International Numbering System (INS) for Food Additives: 544

Food additives Europe numbers: E544 

Calcium polyphosphate isn't a single, well-defined medical substance. Rather, it's a category of compounds that includes various phosphate salts containing calcium. These different types of calcium polyphosphates have various applications, some in medicine and some for other purposes. Here's a breakdown:

In Medicine:

  • Bone Health: Some forms of calcium polyphosphate are being explored as potential bone substitutes or implants due to their ability to promote bone growth [1]. This is still under research and not yet a mainstream medical use.
  • Other Potential Applications: Early research suggests possibilities in areas like:
    • Dentistry (to prevent cavities) [2]
    • Kidney dialysis (to control phosphate levels in the blood) [3]

Important Points:

  • More research is needed to confirm the effectiveness and safety of calcium polyphosphates for these potential medical uses.

In Food and Industry:

  • Food Additive: Certain calcium polyphosphates are used as food additives to:
    • Emulsify ingredients (help them mix together)
    • Prevent spoilage
    • Retain moisture

Safety:

  • The safety profile of specific calcium polyphosphates depends on the exact type and its intended use.
  • Generally recognized as safe (GRAS) by the US Food and Drug Administration (FDA) for certain uses as food additives [4].
