Ferric pyrophosphate
Excellent Acid and Alkali Solubility: Demonstrates ready solubility in inorganic acids, alkaline solutions, and citric acid, facilitating its use in food fortification and nutritional supplements.
Sensory Neutrality: Effectively releases iron in the gastric environment without altering the taste or appearance of food products, thereby ensuring high consumer acceptability.
High Hygroscopicity and Stability: Exhibits moisture-absorbing properties while remaining stable under standard ambient conditions, making it suitable for diverse industrial applications.
Controlled Release Profile: Its insolubility in cold water enables targeted iron release primarily in acidic conditions, allowing for precise bioavailability.
Ferric pyrophosphate presents as a yellow-white, odorless powder with a faint metallic taste. It is soluble in mineral acids, alkaline solutions, and citric acid, yet remains insoluble in cold water. This selective solubility profile makes it particularly valuable for food fortification and iron supplements, as it remains stable in food matrices but dissociates in gastric acid to release bioavailable iron, thereby minimizing undesirable sensory changes to food products. Its stability and low hygroscopicity further support its use in various industrial applications where moisture resistance is required.
