Gluconic Acid
Gluconic acid is an aldonic acid formed by replacing the aldehyde group at position 1 of glucose with a carboxyl group. Type D is produced in large quantities by gluconic acid fermentation of the mold Aspergillus niger (Asp-ergilus niger, etc.), Acetobacter xylinum, and Gluconobacter (Acetobacterxylinum, Gluconobacter, etc.). Glucose oxidase derived from Penicillium notatum can oxidize β-D-glucose to δ-gluconolactone.
Product Usage
Protein coagulant and food preservative. Used to produce gluconate such as sodium gluconate, potassium gluconate, calcium gluconate, etc.
production method
Gluconic acid can be produced by glucose oxidation or biological fermentation.
Sugar acid
Gluconic acid is also known as dextro-gluconic acid. Under the action of weak oxidants or enzymes, the aldehyde group in the molecule is oxidized to a carboxyl group to form a sugar acid. Its 6-phosphate is an intermediate in the oxidative decomposition of glucose in the body (pentose phosphate pathway). It forms a soluble salt with metal ions such as calcium and zinc, which can be used as a nutrient and medicine.
