Uses and synthesis of Sodium gluconate powderFood industry:
Acidity regulator: used to adjust the sourness of food and make it taste softer.
Preservative: can inhibit the growth of microorganisms and extend the shelf life of food.
Chelating agent: can chelate metal ions in food, prevent food from oxidation and deterioration, and maintain the color and flavor of food. For example, it can prevent canned fruits and vegetables from changing color.
Nutritional supplement: as a carrier of minerals such as calcium and magnesium, it improves their solubility and absorption rate in food.
Medical field:
Electrolyte supplement: used to supplement sodium ions in body fluids and maintain electrolyte balance. Commonly used in large-volume parenteral injections.
Drug excipient: used as an excipient in some drug preparations to increase the stability and solubility of drugs.
Industrial field:
Metal surface treatment: used for cleaning steel surfaces to remove rust and dirt.
Electroplating industry: as an additive to electroplating solution, it can improve the brightness and uniformity of the coating.
Concrete admixture: as a retarder, it delays the setting time of concrete and improves its working performance.
Water treatment: used as a water stabilizer to prevent scale formation.
Printing and dyeing industry: used as a color leveling agent to improve dyeing effects.
Functions of Sodium gluconate powder
Core function: ChelationThe most significant function of sodium gluconate is its powerful chelation. Chelation refers to the combination of molecules (here, gluconate ions) with metal ions to form a stable ring-shaped complex. This combination makes the metal ions lose their original activity, thus exerting a series of effects
Preparation method of Sodium gluconate powder.
Glucose oxidation method: Glucose is oxidized to gluconic acid by microbial fermentation or chemical oxidation, and then neutralized with sodium hydroxide to obtain sodium gluconate. This is the main production method at present.
Electrolytic oxidation method: Gluconic acid is prepared by electrolytic oxidation of glucose solution.
Production methodprocess of Sodium gluconate powder
Add the measured amount of calcium gluconate into the reaction kettle, add the aqueous sulfuric acid solution under stirring. After stirring for 1h, it was left to filter, and the slag was CaSO4, which was removed. The filtrate was added to the neutralisation kettle and neutralised by adding appropriate amount of Na2CO3 aqueous solution. Concentration, filtration, drying, qualified packaging Sodium gluconate CAS 527-07-1 .
Sodium gluconate powder is obtained by neutralising glucose with sodium base after fermentation. Add the measured gluconic acid into the reaction kettle, add a little excess of Na2CO3 aqueous solution under stirring to neutralise, stir under 50-60°C for 2h. Concentrate under reduced pressure, cool, crystallise, filter and dry to obtain Sodium gluconate Raw MaterialsWhy choose us?
