Product Categories:

Minerals; food additives; nutrition fortifiers; biochemical reagents-carbohydrates; salt of an organic acid; Organic-metal salt

Chemical Properties:

Light blue crystal or powder, odorless. Melting point is 155~157℃. It is very soluble in water but hardly soluble in ethanol. Mouse oral LD500.419g/kg (Harbin Medical University). Purpose Copper Gluconate   is a good nutritional fortifier. It can be used in formula foods for infants and young children in my country. The usage amount is 7.5-10mg/kg (calculated as copper, the same below); in dairy products, it is 5.7-7.5mg /kg.

  1. D-gluconate glucose as a raw material, it is fermented and oxidized by black mold to generate gluconic acid, and then reacts with copper carbonate (or basic copper carbonate) to generate copper gluconate. This method has huge production equipment, high concentration energy consumption, and difficulty in purification and crystallization. In the direct method, copper gluconate is formed by the direct reaction of calcium gluconate and copper sulfate. The process of this method is simple, but the residual calcium sulfate is difficult to remove. The chemical oxidation method uses glucose as a raw material, oxidizes it to gluconic acid with ozone, and obtains zanolactone gluconate after concentration under reduced pressure and dehydration, and then reacts with copper carbonate to produce copper gluconate.
  2. D-gluconate of calcium gluconate to an equimolar sulfuric acid solution, reacts at 60-90°C for 1 to 2 hours, and filters the precipitated calcium sulfate while it is hot to obtain a colorless or light yellow gluconic acid solution (relative to Density 1.12 ~   1.16). 4g of barium hydroxide aqueous solution and 1.5g of oxalic acid aqueous solution were added dropwise to the above gluconic acid solution, stirred and reacted for 15 minutes to remove residual Ca2+ and S02-. The purified solution is passed through anion and cation exchange resin to obtain a colorless and transparent gluconic acid solution.
  3. D-gluconate 1 mol crystalline copper sulfate solution is mixed with 2 mol sodium hydroxide solution, reacted at 40-60°C for 0.5-1h, filtered, and the filter cake is washed with water to obtain black copper oxide crystals. The copper oxide crystals were added to the gluconic acid solution in batches, reacted for 1 hour, filtered to remove unreacted materials, and allowed to cool and stand for 3 to 5 hours before crystals were precipitated. Add an appropriate amount of 95% ethanol, stir to form a paste, and filter.
  4. D-gluconate the filter cake is vacuum dried at 50°C to obtain a finished product with a yield of 90% to 92.5%.
