Ferric pyrophosphate is a yellowish-white to yellow-brown powder that is slightly soluble in water and acetic acid, but can dissolve in inorganic acids, alkaline solutions, and citrate salts. This compound has a stable structure, is not easily oxidized, and is heat-resistant. These properties make it highly suitable for use as a food additive and in other applications. Ferric pyrophosphate contains up to 24% to 30% iron, making it an effective source of iron nutrition.
Ferric pyrophosphate (chemical formula Fe4(P2O7)3) is an important inorganic compound that plays a significant role in various industries due to its unique chemical properties and wide range of applications:
1. Food Additive and Nutritional Fortifier
·Enhancing Nutritional Value: Ferric pyrophosphate, as a source of iron, can be used in foods such as flour, biscuits, bread, dried milk powder, rice flour, and soy milk powder to enhance their nutritional value.
·Meeting the Needs of Different Groups: In foreign countries, ferric pyrophosphate is widely used in infant formula foods, health supplements, convenience foods, and functional fruit juice drinks to meet the iron nutritional needs of different groups.
·Improving Sensory Characteristics: Ferric pyrophosphate has no special odor, and its lighter color does not adversely affect the color or taste of the product.
2. Flame Retardant for Synthetic Fibers
By adding ferric pyrophosphate, the fire resistance of fiber materials can be significantly improved, helping them maintain stability during fires and reducing damage to life and property.
3. Anti-corrosive Pigment and Catalyst
·Anti-corrosive Pigment: Adding ferric pyrophosphate to anti-corrosion coatings can extend the lifespan of the coating and prevent metal materials from corroding.
·Catalyst: Ferric pyrophosphate serves as a catalyst in chemical reactions, enhancing reaction efficiency and reducing production costs.
4. Pharmaceutical Excipients
