Sodium Gluconate has very complete functions and can be used as a water reducing agent, preservative, color leveling agent, etc. in food, construction, dyes and other industries. Sodium gluconate is easily soluble in water, both in cold water and in boiling water. , can be used as a heating agent in industrial production.
In the food industry, sodium gluconate can react with sodium bicarbonate to generate carbon dioxide after heating, which has a good bulking effect and can be used as a bulking agent for puffed food without peculiar smell. Sodium gluconate can be added in pastry making and fried food cooking to improve the softness of the food and increase the swelling effect. For example, as the most characteristic breakfast fried dough sticks in China, adding sodium gluconate in an appropriate amount during the frying process can improve the softness of the fried dough sticks and make them more delicious.
When sodium gluconate is used as a heating agent, it can be used as an energy-saving agent in industries that require heat energy. Sodium gluconate is soluble in boiling water, and the higher the temperature, the higher the solubility. When used as a heating agent , it must be used according to the amount. If the amount is too large, it will have the opposite effect of suppressing the heating. Use according to the amount, the best is the proportion range of 5% to 30%.
For industrial grade products, sodium gluconate is widely used as a cement retarder, which can effectively prevent solidification and agglomeration during commercial concrete transportation; etchant. For food-grade and pharmaceutical-grade products, sodium gluconate can adjust the acid-base balance of the human body, ensure the normal function of nerves, and effectively prevent the occurrence of low sodium syndrome.
It is used as food additives and pharmaceutical intermediates. Sodium gluconate has obvious coordination effect and is suitable for various formulations such as molybdenum, silicon, phosphorus, tungsten, nitrite, etc.; the corrosion inhibition rate increases with the increase of temperature; the scale inhibition ability is strong, and it has strong resistance to calcium, magnesium and iron salts. Strong complexing ability; as a corrosion and scale inhibitor for circulating cooling water, it is also a major advantage of sodium gluconate to achieve pollution control.
In industry, the substance containing glucose is generally used as the raw material, and gluconic acid is first prepared from glucose by fermentation method, and then neutralized by sodium hydroxide to obtain sodium gluconate, and electrolysis and oxidation synthesis can also be used. According to the different types of fermentation enzymes used, the fermentation method can be divided into two minutes, one is using the enzyme of Aspergillus Niger, the other is acid, the latter method forms lactones by dehydrogenation of glucose, and then decomposes the esters. Sodium gluconate can also be obtained directly from glucose fermentation.
At this time, the composition of the fermentation base can be: glucose 250-350 g/L, magnesium sulfate heptahydrate 0.2-0.3 g/L, diammonium hydrogen phosphate or urea 0.4-0.5 g/L. This matrix must be sterilized. During the fermentation process, the temperature is controlled at 30-32 degrees, the pH is controlled at 5.5-6.5 by means of 30%-50% sodium hydroxide, and the fermentation process lasts for 40-100 hours. Then, microorganisms are removed by filtration and washing, activated carbon is decolorized, filtered again, and the result is concentrated or spray-dried to obtain the finished product.
