The role and use of sodium gluconate

  Sodium gluconate, also known as sodium pentahydroxycaproate, is a white or light yellow crystalline powder, easily soluble in water, slightly soluble in alcohol, insoluble in ether.
  Sodium gluconate is a common and widely used organic acid sodium salt. Industrial grade sodium gluconate is often used in construction, chemical industry and other industries. In the construction industry, it is often used as a cement additive to reduce water and slow coagulation. In the chemical industry, it is used as the basic raw material for the production of other gluconates, gluconic acid and gluconolactone, and also has good applications in electroplating, cleaning agent, film manufacturing and water quality treatment. Food grade sodium gluconate is often used in the food and pharmaceutical industry. In the food industry, as a food additive, it plays a role in regulating taste, regulating acidity, dehydration, curing, etc. In the pharmaceutical industry, it can regulate acid-base balance and maintain extracellular osmotic pressure.
  Sodium gluconate is widely used in industry, sodium gluconate can be used in construction, textile printing and dyeing and metal surface treatment and water treatment industries as a high-efficiency chelating agent, steel surface cleaning agent, glass bottle cleaning agent, electroplating industrial aluminum oxide coloring, in the concrete industry as a high-efficiency retarder, high-efficiency water reducing agent.

  In the food industry：

  Sodium gluconate can replace table salt: the salt taste of sodium gluconate is close to table salt, and the molecular weight of sodium is only 10.5%, compared with table salt, the former sodium content is only 1/4 of the latter. Compared with other low sodium salts, sodium gluconate has the advantages of non-irritating, non-bitter, and salty taste, and has become the best substitute for salt. At present, it is widely used in salt-free soy sauce, bread and other food fields. In white bread, sodium gluconate completely replaces sodium chloride, which does not cause a difference in the volume of bread, and does not affect its overall flavor and shelf life.

  Sodium gluconate can improve food flavor: sodium gluconate has the effect of covering up the bitterness of food, shielding the odor, improving the taste and so on, and has a significant effect on the improvement of food flavor. By adding sodium gluconate to low-fat cheese, the original bitter and astringent taste of low-fat cheese was eliminated, and the overall taste was improved. By comparing the flavor of lactone tofu prepared with sodium gluconate and gypsum as coagulant, it is found that the tofu prepared with sodium gluconate is more tender, and has higher taste and nutritional value.
  Sodium gluconate can enhance the nutritional properties of food: can enhance the nutritional properties of food.
