Calcium Pyrophosphate

Calcium Pyrophosphate (Ca₂P₂O₇) is a food-grade white, odorless, tasteless crystalline powder used in food applications as a source of calcium and phosphorus, as a mild abrasive in oral care, and as a dietary mineral supplement.We supply bulk Calcium Pyrophosphate sourced from leading China manufacturers, available in powder form for global food and beverage producers. Our Calcium Pyrophosphate is widely used in foods and beverages, tablets, dairy alternatives, infant formula mineral fortification and toothpaste as a mild polishing agent.

Introduction

Calcium Pyrophosphate is produced by the controlled thermal dehydration of calcium hydrogen phosphate (dicalcium phosphate) or by reacting calcium chloride with sodium pyrophosphate. In food applications it primarily serves as a mineral fortification source. It provides both calcium (~31%) and phosphorus (~22%) in a form with high bioavailability and low solubility that minimizes off-flavors and reactions.

It is listed as E450(vii) in the EU and is GRAS under FDA 21 CFR 182.8223. Its low water solubility makes it particularly useful in heat-treated dairy alternatives, fortified beverages where taste neutrality is critical, and powdered mixes. In oral care it functions as a gentle polishing agent in toothpaste formulations. Food-grade Calcium Pyrophosphate meets Food Chemicals Codex (FCC), JECFA, and Codex specifications.

Uses

Calcium and phosphorus fortification in foods and beverages
Nutritional supplement formulations and tablets
Dairy alternatives (plant milks, dairy-free products)
Infant formula mineral fortification
Toothpaste as a mild polishing agent
