The sodium–potassium pump, a critical enzyme for regulating sodium and potassium levels in cells. Sodium ions (Na +) are necessary in small amounts for some types of plants, [1] but sodium as a nutrient is more generally needed in larger amounts [1] by animals, due to their use of it for generation of nerve impulses and for maintenance of electrolyte balance and fluid balance.
Sodium erythorbate (C 6 H 7 NaO 6) is a food additive used predominantly in meats, poultry, and soft drinks. Chemically, it is the sodium salt of erythorbic acid.
Food Industry: Sodium Gluconate is used as a food additive for various purposes, including as a sequestrant to prevent metal ions from affecting the color, flavor, or stability of food products. Construction: Sodium Gluconate is employed in the construction industry as a concrete admixture. It acts as a water reducer and retarder, enhancing the ...
The sodium ion (Na +) is an important electrolyte in neuron function, and in osmoregulation between cells and the extracellular fluid. This is accomplished in all animals by Na + /K +-ATPase, an active transporter pumping ions against the gradient, and sodium/potassium channels. [104]
Sulfites used in food processing (but not as a preservative) are required to be listed if they are not incidental additives (21 CFR 101.100(a)(3)), and if there are more than 10 ppm in the finished product (21 CFR 101.100(a)(4)) On July 8, 1986, sodium bisulfite (and other sulfites : "The chemicals affected by the order are sulfur dioxide ...
The sodium–potassium pump is a critical enzyme for regulating sodium and potassium levels in cells. Potassium is the main intracellular ion for all types of cells, while having a major role in maintenance of fluid and electrolyte balance. [1] [2] Potassium is necessary for the function of all living cells and is thus present in all plant and ...
A sequestrant is a food additive which improves the quality and stability of foods. [1] A sequestrant forms chelate complexes with polyvalent metal ions, especially copper, iron and nickel. This can prevent the oxidation of the fats in the food. Sequestrants are therefore a type of preservative.
Ion exchange is widely used in the food and beverage industry, hydrometallurgy, metals finishing, chemical, petrochemical, pharmaceutical technology, sugar and sweetener production, ground- and potable-water treatment, nuclear, softening, industrial water treatment, semiconductor, power, and many other industries.
