Sodium gluconate is an organic substance composed of many hydroxyl groups, called sodium pentahydroxylate. The appearance is white or brown-yellow crystalline particles or powder. It is easily soluble in water, slightly soluble in ethanol, and insoluble in ether.
It has a wide range of industrial uses. Sodium gluconate can be used as a high-efficiency chelating agent in construction, textile printing and dyeing, metal surface treatment and water treatment industries, steel surface cleaning agent, glass bottle cleaning agent, aluminum oxide coloring in electroplating industry, and used in concrete industry As high-efficiency retarder, high-efficiency water reducer, etc.
In industry, substances containing glucose (such as grains) are generally used as raw materials, and gluconic acid is obtained from glucose by fermentation, and then neutralized by sodium hydroxide to obtain sodium gluconate. Electrolysis and oxidation can also be used. synthesis. Most of our country adopts chemical oxidation method-hypobromide oxidation method to produce and synthesize.
Sodium gluconate is not dangerous. It is non-toxic. Industrial glucose is whole sugar or food grade glucose. White lumpy solid, fragrant and sweet.
Sodium gluconate in food industry,as gelatinizing agent,thickener,deflocculant used in health food such as ice cream, beverage, form food, meat product, jam, etc.
