| Sugar acid | Gluconic acid is also called dextrogluconic acid. Under the action of weak oxidants or enzymes, the aldehyde group in the molecule is oxidized to carboxyl A sugar acid formed. Its 6-phosphate is an intermediate of the oxidative decomposition of glucose in the organism (pentose phosphate pathway). It forms soluble salts with metal ions such as calcium and zinc as nutrients and drugs. |
| uses | calcium salt, ferrous salt, bismuth salt and other salts of gluconic acid can be used as medicine; the metal complexes of this product are widely used in alkaline systems The masking agent for metal ions; aqueous solution is used as a food sour agent; the preparation of sake; bottle washing agent; de-lactis for dairy equipment, etc. Protein coagulants and food preservatives. Used to produce gluconate such as sodium gluconate, potassium gluconate, calcium gluconate, etc. Used as protein coagulant and food preservative |
| Preparation method | ① Glucose can be oxidized to produce gluconic acid [1]. [1] can be prepared under the action of weak oxidants (such as bromine water); under the action of strong oxidants, in addition to the aldehyde group being oxidized to form a carboxyl group, the primary alcohol group is also oxidized to a carboxyl group to form glucosaric acid. ② citric acid is used as raw material, and aftromycin strain is used for fermentation at 25~30 ℃ at pH = 3.5 or above to obtain [1]. At the same time, oxalic acid is produced. Then use calcium hydroxide to separate and remove oxalic acid. fig. 2 is a chemical reaction roadmap for preparing gluconic acid from citric acid. ③Glucose is electrolytically oxidized in alkaline solution to produce [1]. ④ calcium gluconate (or sodium) is decomposed with sulfuric acid, refined by ion exchange resin, evaporated and concentrated to obtain [1]. |
| Production method | Gluconic acid can be produced by glucose oxidation or biological fermentation. |
