Ferrous Gluconate (CAS 299-29-6, food grade), with the molecular formula C₁₂H₂₂FeO₁₄·nH₂O (n=0 or 2), has a theoretical iron content of 11.6%. It appears as a grayish-yellow or light yellow-green crystalline powder with a faint caramel-like burnt odor. It is highly soluble in water, with a solubility of approximately 8 g/100 mL at room temperature.
- As a nutritional supplement (iron fortifier), ferrous gluconate is widely used in grain products, dairy products, infant and toddler foods, beverages, and health supplements. It also serves as a color adjunct in food applications.
- In the pharmaceutical field, ferrous gluconate is favored for treating iron-deficiency anemia in children due to its pleasant taste and low gastrointestinal irritation, making it suitable for long-term use.
Usage
As a color protectant and nutrient enhancer in the food industry, it has the characteristics of high bioavailability, good water solubility, and mild flavor. It is commonly used for strengthening dairy beverages.
