Ferrous Gluconate Dihydrate powder Usage and Synthesis.

Ferrous gluconate is a color protectant and nutrient fortifier commonly used in foods. It is characterized by high bioavailability, good solubility, and a calm, non-astringent flavor.

Ferrous gluconate can be obtained by neutralizing reduced iron with gluconic acid, or by heating an aqueous solution of ferrous carbonate and gluconic acid. Ferrous gluconate has good solubility in water, but excessive fortification in milk beverages is likely to cause changes in food color and flavor.

Ferrous gluconate is used medically as a drug for the treatment of diseases such as anemia. Its pharmacological effects include increasing hemoglobin levels and improving the morphology of blood red blood cells. The dosage of Ferrous Gluconate needs to be based on the patient's specific condition, and the adverse reactions and interactions of the drug need to be noted.

When taking ferrous gluconate, you need to pay attention to the interaction with milk, tea and other foods. The proteins and phosphorus in milk can affect the absorption of iron, while the tannins in tea can form precipitates with iron and reduce the absorption of iron.

Uses and functions of Ferrous Gluconate Dihydrate powder.

Ferrous gluconate salt is a commonly used drug, mainly for the treatment of iron deficiency anemia.

In addition, it is used as a food additive to impart acidity, enhance the flavor of foods, prevent protein denaturation, improve undesirable bitter and astringent tastes, and replace salt to obtain low-sodium and sodium-free foods.

Ferrous gluconate salt has high bioavailability, good solubility, and a calm, non-astringent flavor, but it is more fortified in milk beverages and is also prone to cause changes in food color and flavor.

Preparation of Ferrous Gluconate Dihydrate powder.

Product Method of Bulk Ferrous Gluconate Dihydrate powder.

(1) Direct method. Calcium glucose and ferrous sulfate in the presence of a small amount of iron powder in the reaction at 90 ℃ for 10h, you can get the product, the yield of 97.8%. The method is simple, but the residual amount of calcium sulfate is too high and difficult to remove.

(2) Acid method. Add 1.2 mol/L calcium gluconate to the same amount of sulfuric acid solution under stirring, and react at 90 ℃ for 1h; after filtration to remove the precipitated calcium sulfate precipitate, pass the column at a flow rate equivalent to the volume of the resin per minute, and get about 35% of the gluconic acid solution, yield 97%.

Ferrous sulfate powder is added to calcium carbonate solution, stirring to dissolve and react to produce ferrous carbonate precipitate: after the end of the reaction is filtered, washed to get ferrous carbonate (do not drain, the surface retains a layer of water in order to isolate the air), yield 98%.

Then add the ferrous carbonate into the gluconic acid solution stirring reaction for 30min, the reaction of CO2 generated as an inert gas to play a protective role. The product ferrous gluconate solution was put into the crystallization tank, and add the crystal seed, about 3-5h crystallization is completed. Finally filtered and washed with ethanol, 50 ℃ vacuum drying that is the finished product, yield 98%.
