Sodium gluconate CAS 527-07-1

Sodium gluconate is widely used in food and industry. It can be used as an efficient chelating agent in industries such as construction, textile printing and dyeing, metal surface treatment, and water treatment. It can also be used as a steel surface cleaning agent, glass bottle cleaning agent, aluminum oxide coloring agent in electroplating industry, and as an efficient retarder and water reducer in the concrete industry. Sodium gluconate used in the food industry can replace table salt: the taste and quality of sodium gluconate are similar to table salt, and the molecular weight of sodium only accounts for 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 bitter taste, and a salty and pungent taste, making it the best substitute for table salt. Currently widely used in the food industry such as salt free soy sauce and bread. In white bread, sodium gluconate completely replaces sodium chloride, which does not cause a difference in bread volume, nor does it affect its overall flavor and shelf life. Sodium gluconate can improve food flavor: Sodium gluconate has the effects of masking bitterness, blocking off odors, and improving taste, and has a significant effect on improving food flavor. By adding sodium gluconate to low-fat cheese, the original bitterness and astringency of low-fat cheese are eliminated, improving the overall taste. By comparing the flavor of lactone tofu made with sodium gluconate and gypsum as coagulants, it was found that tofu made with sodium gluconate was more tender, with higher taste and nutritional value. Sodium gluconate can enhance the nutritional properties of food: it can enhance the nutritional properties of food. Through in-depth research on the phenomenon of cheese hardening, it was found that sodium gluconate can form soluble complexes with calcium ions and lactate ions in cheese, thereby increasing the solubility of calcium lactate. This not only effectively prevents cheese hardening, but also ensures the nutritional quality of cheese. Used as a steel surface cleaning agent. When steel surfaces require plating bowl, chrome plating, tin plating, nickel plating to adapt to special purposes, such as manufacturing tinplate, galvanized sheet, surface chrome plating (electroplating), etc., the surface of the steel billet needs to be strictly cleaned to firmly bond the coating material with the steel surface. At this time, adding sodium gluconate to the cleaning agent will achieve very ideal results. Adding a certain amount of sodium gluconate to cement as a cement admixture can increase the plasticity and strength of concrete, and has a blocking effect, which delays the initial and final setting time of concrete; The professional cleaning agent for glass bottles, mainly formulated with sodium gluconate, can improve the following common problems: weak descaling ability, easy blockage of the nozzle and pipeline of the bottle washing machine; Poor stain removal ability for bottle stickers and bottleneck rust; Trace residues after washing are not ideal for food safety (such as phosphate residues); The discharge of washing water is a public hazard. As a water quality stabilizer, sodium gluconate is widely used due to its excellent corrosion and scale inhibition effects, such as as as a treatment agent for circulating cooling water systems, low-pressure boilers, internal combustion engine cooling water systems, etc. in petrochemical enterprises. Because it has the following specific advantages: ⑴ It has a significant coordinating effect. Suitable for formulas such as molybdenum, silicon, phosphorus, tungsten, nitrite, etc. Due to the coordination effect, the corrosion inhibition effect is greatly improved. The corrosion inhibition rate increases with increasing temperature. The corrosion inhibition rate of general corrosion inhibitors decreases with increasing temperature, and may even completely lose their effectiveness. But sodium gluconate, on the contrary, has a corrosion inhibition rate that increases with temperature within a certain range. ⑶ Strong scale inhibition ability: It has a strong chelating ability for calcium, magnesium, and iron salts, so its scale inhibition ability is very strong, especially for Fe3+, which has excellent chelating effect and even works within the entire pH range. ⑷ Eliminate public hazards. The use of sodium gluconate as a corrosion and scale inhibitor for circulating cooling water achieves the elimination of pollution, which is an advantage that other corrosion and scale inhibitors currently in use cannot compare to.
