Sodium gluconate is a common and widely used organic sodium salt. Industrial grade sodium gluconate is commonly used in construction, chemical industry and other industries. In the construction industry, it is often used as a cement additive to reduce water and retard setting. In the chemical industry, it is often used as the basic raw material for producing other gluconate, gluconic acid and gluconolactone. It also has good application in chemical book electroplating, cleaning agent, film manufacturing, water quality treatment, etc. Food grade sodium gluconate is commonly used in the food and pharmaceutical industries. In the food industry, as a food additive, it can regulate taste, acidity, dehydration and solidification. In the pharmaceutical industry, it can regulate acid-base balance and maintain extracellular osmotic pressure.
Sodium gluconate is widely used in food and industry. Sodium gluconate can be used as 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, and aluminum oxide coloring in electroplating industry,used as high-efficiency retarder,high-efficiency water-reducing agent, etc. in the concrete industry.

For the food industry

Sodium gluconate can replace table salt: the salt taste of sodium gluconate is close to that of table salt, and the molecular weight of sodium is only 10.5%. Compared with table salt, the sodium content of the former is only 1/4 of the latter. Moreover, compared with other low-sodium salts, sodium gluconate has the advantages of no irritation, no bitterness, no salty taste, etc., and has become the best substitute for table salt. At present, it is widely used in unsalted soy sauce, bread and other food fields. In white bread, sodium gluconate completely replaces sodium chloride, which will not cause differences in bread volume, and will not affect its overall flavor and shelf life.

Sodium gluconate can improve food flavor: sodium gluconate has the functions of masking the bitter taste of food, shielding peculiar smell, improving taste, etc., and has a significant effect on the improvement of food flavor. By adding sodium gluconate to low-fat cheese, the original bitterness and astringency of low-fat cheese are eliminated, and the overall taste is improved. By comparing the flavors of lactone tofu made with sodium gluconate and gypsum as coagulants, it was found that the tofu made with sodium gluconate was more tender, with higher taste and nutritional value.

Sodium Gluconate Enhances the Nutritional Properties of Foods: Enhances the nutritional properties of foods. For example, through in-depth research on the phenomenon of cheese hardening, it was found that sodium gluconate can form a soluble complex with calcium ions and lactate ions in cheese, thereby increasing the solubility of calcium lactate, which not only effectively prevents cheese from hardening, but also ensures the nutritional quality of cheese.

Used as steel surface cleaner
If the steel surface needs to be plated with pot, chrome, tin and nickel for special purposes, such as manufacturing tinplate, galvanized sheet, surface chrome plating (electroplating), etc., the surface of the billet must be strictly cleaned to make the coating and steel surface Firmly combined, at this time, adding sodium gluconate to the cleaning agent will achieve a very ideal effect.
as cement admixture
After adding a certain amount of sodium gluconate to the cement, it can increase the plasticity and strength of the concrete, and has a retarding effect, that is, delaying the initial and final setting time of the concrete;

Used as a special cleaning agent for glass bottles
The professional glass bottle cleaning agent with sodium gluconate as the main formula can improve the following common problems: weak detergency, easy to block the nozzle and pipeline of the bottle washer; After trace residues are not ideal for food safety (such as phosphate residues); washing water discharges into a public nuisance.

Used as water stabilizer
Due to its excellent corrosion and scale inhibition properties, sodium gluconate is widely used as a water stabilizer, for example, as a treatment agent for circulating cooling water systems in petrochemical enterprises, low-pressure boilers, and cooling water systems for internal combustion engines. Because it has the following specific advantages: ⑴ has obvious coordination effect. It is suitable for formulas such as molybdenum, silicon, phosphorus, tungsten and nitrite. Due to the coordination effect, the corrosion inhibition effect is greatly improved. (2) The corrosion inhibition rate increases with the increase of temperature. Generally, the corrosion inhibition rate decreases with the increase of temperature, or even loses its effect completely. But sodium gluconate is just the opposite, and the corrosion inhibition rate increases with the increase of temperature within a certain range. (3) Strong anti-scaling ability: It has strong complexing ability for calcium, magnesium and iron salts, so it has strong anti-scaling ability, especially has excellent chelating effect on Fe3+, even in the whole PH range. ⑷ eliminate public nuisance. The use of sodium gluconate as a corrosion and scale inhibitor for circulating cooling water can eliminate pollution, which is an incomparable advantage of other corrosion and scale inhibitors currently used.
