Ferrous gluconate
Ferrous gluconate, molecular formula is C12H22O14Fe · 2H2O, relative molecular mass is 482.18. In food can be used as color protection agent, nutrition enhancer, can be reduced by iron and gluconic acid. Ferrous gluconate is characterized by high bioavailability, good solubility in water, mild flavor and no astringency, and is more fortified in milk drinks, but it is also easy to cause changes in food color and flavor, which limits its application to a certain extent.

Nature
Ferrous gluconate is yellow-gray or light yellow-green crystalline granules or powder with a slight caramel odor. Soluble in water, 5% aqueous solution is acidic, almost insoluble in ethanol, theoretical iron content of 12%. Ferrous gluconate is easy to absorb, has no stimulation to the digestive system, no side effects, and has no effect on the sensory properties and flavor of food, and can be used as a drug to treat anemia.
identification method
(1) Add 0.65mL of glacial acetic acid and 1mL of newly distilled phenylhydrazine to 5mL of warm 10% sample solution, heat on a steam bath for 30min, and scrape the inner wall of the container with a glass rod after cooling to generate phenylhydrazine gluconate crystals.
(2)5% of this product solution is ferrous salt reaction (see ferrous sulfate identification method).
