Uses
1. It is used for the production of zinc supplement food, nutritional oral liquid, children zinc supplement tablets and granules.
2. Zinc lactate is a zinc food fortifier with excellent performance and ideal effect. It plays an important role in the intellectual and physical development of infants and adolescents, and its absorption effect is better than that of inorganic zinc. It can be added to various products such as milk, milk powder, and cereals. China's regulations (both in terms of zinc): the dosage in dairy products is 30-60 mg/kg; the dosage in infant food is 25-70 mg/kg; the dosage in cereals and their products is 5-10 mg/kg; drinking liquid The dosage for medium use is 5-10mg/kg; the dosage for children's oral liquid is 0.6-1.0g/kg (calculated as zinc lactate).

Precautions
China's "Hygienic Standards for the Use of Food Nutrition Fortifiers" (GB14880-1994) stipulates: Cereals and their products, 90-180 mg/kg; liquid and milk beverages, 22.5-45 mg /kg; dairy products, 135~270 mg/kg; infant food, 112.5~315 mg/kg. my country's "Hygienic Standard for the Use of Food Additives" (GB2760-1996) stipulates: oral liquid for children, 600~1000 mg/kg.
Drug testing
① Take 5 mL of this product solution (10 g/100 mL), put it in a test tube, add 1 mL of bromine test solution (20%) and 0.5 mL of dilute sulfuric acid (1+10), heat it on a water bath, and use Stir the glass rod until the yellow color subsides, add 4 g of ammonium sulfate and mix well, and gradually add 0.2 mL of 10% sodium ferricyanide dilute sulfuric acid solution and 1 mL of concentrated ammonia solution along the tube wall to form two liquid layers. After standing for 30min, a dark green ring appeared at the interface of the two liquid layers.
② Take 5 mL of this product solution (10 g/100 mL), add the newly prepared potassium ferrocyanide test solution (10 g/100 mL), white precipitate will occur, separate, and the precipitate will not dissolve in dilute hydrochloric acid.
③ Take 5 mL of this product solution (10 g/100 mL), acidify it with 10% dilute sulfuric acid, add 1 drop of copper sulfate solution (1 g/L) and a few drops of 5% mercuric ammonium thiocyanate solution, and a purple precipitate will be formed .
