ZINC LACTATE DIHYDRATE - Application
Open Data Verified Data
zinc lactate is a kind of zinc food fortifier with excellent performance and ideal effect. It plays an important role in the intelligence and physical development of infants and adolescents, and the absorption effect is better than that of inorganic zinc. Can be added to milk, milk powder, grain cereals and other products. China's regulations (are zinc): the amount of 30~60 mg/kg in dairy products, infant food usage of 25~70mg/kg; grain and its products in the use of 5~10 mg/kg; Drink in the use of 5~10 mg/kg; Children oral liquid dosage of 0.6~1. Og/kg (zinc lactate).

| dosage | China stipulates that zinc lactate can be used in dairy products, and the usage amount is 30-60 mg/kg (in terms of zinc, the same below); The usage amount in infant food is 25-70 mg/kg; The usage amount in cereals and their products is 5-10 mg/kg; The usage amount in drinking liquid is 5-10 mg/kg; the maximum dosage in children's oral liquid is 0.6~1.0 g/kg (calculated as zinc lactate). |
| use | zinc lactate can be used in the production of zinc supplement food, nutrition oral liquid, children's zinc supplement tablets and granules. it is a good food zinc fortifier and is widely used in cakes, beverages, various nutrient solutions, flour, nutrition salt, dairy products and bean products. it plays an important role in the intellectual and physical development of infants and adolescents, the absorption effect is better than that of inorganic zinc. Zinc lactate can also replace glycerin in tobacco products as a fragrance, antifreeze and moisturizer for cut tobacco; in cosmetics, it can also be used in facial cleanser, beauty cream, lotion, shampoo, and facial mask. |
| production method | 1. metathesis method adds 13.0g of calcium lactate (pentahydrate) and 12.1g of zinc sulfate (heptahydrate) to 100mL of water, stirring, heating and reflux reaction. After the reaction is over, filter while hot and wash with water to remove calcium sulfate precipitate (light blue and white powder). The filtrate is a milky white translucent liquid. When it is cooled and left to stand, white crystals will precipitate. Finally, 8g of white powder (melting point 276~27 7 ℃) was obtained by filtration, washing with water and drying with 64% yield. (C3H503)2Ca+ZnSO4→ (C3H5O3)2 Zn+CaSO4↓2. In the neutralization method, zinc oxide powder is added to the finished lactic acid solution for heating and stirring for 2~3h. The reactants are cooled and crystallized, filtered and separated, washed with water for several times, and then dried at 60~65 ℃ to obtain the finished product. This method is simple in process, good in quality, but high in cost. 2C3H6O3+ZnO→(C3H5O3)2Zn+H2O3. It can also be fermented from starch to obtain lactic acid, and then react with zinc salt to obtain zinc lactate. |
