Sodium gluconate is an organic compound, the sodium salt of gluconic acid. Molecular formula – NaC6H11O7, structural form – HOCH2(CHOH)4COONa. Alias: sodium gluconate, sodium D-gluconate. It is obtained by processing cellulose.
Colorless small crystalline powder. Slightly soluble in water, soluble in ethanol. Easily reacts with acids and bases.
Sodium gluconate is considered a harmless additive that not only enhances taste, but also increases hunger and stimulates people to eat more. In addition, in large doses, the substance can cause allergies, headache, dizziness, irritation and rash, tachycardia, increased sweating. Regular consumption can become addictive, and foods without this additive start to look dull.
Most commonly used as food additive E576. It belongs to the category of flavor enhancers. It enhances taste by increasing the sensitivity of the tongue receptors, saturating the taste of protein products (meat, fish, mushrooms). It is required in the manufacture of semi-finished products, soy sauce, bouillon cubes, potato chips, meat and fish seasonings. In restaurants and fast food restaurants, it is used in its pure form as a seasoning. Also used as a styling agent, emulsifier, acidity regulator. Boosts the power of antioxidants to help bind and produce indigestible excess iron, calcium and heavy metals.
In the food industry – washing membranes for ultrafiltration separation of milk; cleaning food bottles; descaling beer brewing tanks.
Included in laundry detergents and household detergents, bleach, shampoos.
Sodium Gluconate produces professional alkaline cleaners for industrial removal of organic and inorganic deposits; rust, carbon and silicate deposits on glass surfaces. Adding sodium gluconate to liquid products helps to use them in water of any hardness. In addition, the agent enhances the action of other components, reducing their corrosiveness and increasing their solubility in water.
Improves the plasticity of solutions in building and concrete mixtures. Due to the addition of sodium gluconate, the concrete sets more slowly and requires less water to prepare the mortar. Ready-made concrete containing reagent additives is characterized by an increase in strength.
In the petroleum industry, it is used for cementing wells, extending service life, strengthening drill strings, protecting well walls from pressure and corrosion from surrounding formations, and preventing fluid loss in the well. The substance is used to prevent “loading” of the well (salt deposits impair the permeability of the well to oil and gas; the agent keeps the salt in a soluble form). When used in drilling fluids containing alkaline agents, the addition of sodium gluconate protects the cast iron and steel components of the drill bit and drill string from corrosion.
In metallurgy – in the smelting of steel and aluminium, in the pickling of steel.
In pharmacology and medicine as a regulator of water-salt balance. Dropper for anti-shock detoxification treatment; frostbite, burns, massive blood loss; restoration of electrolyte balance; in the treatment of peritonitis.
